Two deposition sites were established on the east side of the park: one at an elevation of 2,902 meters near Bear Lake for nutrients and pesticides, and one at an elevation of 3,159 meters in the Loch Vale watershed for mercury. Concentrations of nutrients in summer precipitation at Bear Lake ranged from less than 0.007 to 1.29 mg N/L (milligrams of nitrogen per liter) for ammonium and 0.17 to 4.59 mg N/L for nitrate and were similar to those measured at the Loch Vale National Atmospheric Deposition Network station, where nitrogen concentrations in precipitation are among the highest in the Rocky Mountains. Atrazine, dacthal, and carbaryl were the most frequently detected pesticides at Bear Lake, with carbaryl present at the highest concentrations (0.0079 to 0.0952 ?g/L (micrograms per liter), followed by atrazine (less than 0.0070 to 0.0604 ?g/L), and dacthal (0.0030 to 0.0093 ?g/L). Mercury was detected in weekly bulk deposition samples from Loch Vale in concentrations ranging from 2.6 to 36.2 ng/L (nanograms per liter). \r\n\r\nConcentrations in summer precipitation were combined with snowpack data from a separate study to estimate annual deposition rates of these contaminants in 2002. Annual bulk nitrogen deposition in 2002 was 2.28 kg N/ha (kilograms of nitrogen per hectare) at Bear Lake and 3.35 kg N/ha at Loch Vale. Comparison of wet and bulk deposition indicated that dry deposition may account for as much as 28 percent of annual nitrogen deposition, most of which was deposited during the summer months. Annual deposition rates for three pesticides were estimated as 45.8 mg/ha (milligrams per hectare) of atrazine, 14.2 mg/ha of dacthal, and 54.8 mg/ha of carbaryl. Because of much higher pesticide concentrations in summer precipitation than in winter snow, between 80 to 90 percent of the annual pesticide deposition occurs during summer. Mercury deposition to Loch Vale was estimated at 7.1 ?g/m2 (micrograms per square meter) of which nearly 70 percent of the annual mercury deposition occurred during summer. Despite the fact that most precipitation at high-elevations falls during winter, these results emphasize the importance of monitoring precipitation chemistry during summer to improve estimates of contaminant deposition to high-elevation ecosystems in Rocky Mountain National Park.\r\n\r\nAir-parcel back trajectories were calculated using an atmospheric transport model to identify potential source regions for contaminants reaching the park. The results indicate that during the winter, the most likely source of contami-nants is from areas northwest of the park, but during summer, contaminants are most likely coming from sources to the southwest and east.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri034241","usgsCitation":"Mast, M.A., Campbell, D.H., Ingersoll, G.P., Foreman, W., and Krabbenhoft, D.P., 2003, Atmospheric deposition of nutrients, pesticides, and mercury in Rocky Mountain National Park, Colorado, 2002 (Online Only): U.S. Geological Survey Water-Resources Investigations Report 2003-4241, 15 p., https://doi.org/10.3133/wri034241.","productDescription":"15 p.","onlineOnly":"Y","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":177674,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4702,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri034241/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Colorado","otherGeospatial":"Rocky Mountain National Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -105.93017578125,\n              40.14109012528468\n            ],\n            [\n              -105.48110961914062,\n              40.14109012528468\n            ],\n            [\n              -105.48110961914062,\n              40.57224011776902\n            ],\n            [\n              -105.93017578125,\n              40.57224011776902\n            ],\n            [\n              -105.93017578125,\n              40.14109012528468\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","edition":"Online Only","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d878","contributors":{"authors":[{"text":"Mast, M.

The contamination resulted from artillery use and weapons testing at various ranges upgradient of the pond.The diffusion samplers were constructed with a high-grade cellulose membrane that allowed diffusion of explosive compounds, such as RDX (Hexahydro-1,3,5-trinitro-1,3,5-triazine) and HMX (Octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine), into deionized water inside the samplers. Laboratory tests confirmed that the cellulose membrane was permeable to RDX and HMX. One transect of 22 diffusion samplers was installed and retrieved in August-September 2001, and 12 transects with a total of 108 samplers were installed and retrieved in September-October 2001.  \r\n\r\nThe diffusion samplers were buried about 0.5 feet into the pond-bottom sediments by scuba divers and allowed to equilibrate with the ground water beneath the pond bottom for 13 to 27 days before retrieval. Water samples were collected from temporary well points driven about 2-4 feet into the pond bottom at 21 sites in December 2001 and March 2002 for analysis of explosives and perchlorate to confirm the diffusion-sampling results. \r\n\r\nThe water samples from the diffusion samplers exhibited numerous chromatographic peaks, but evaluation of the photo-diode-array spectra indicated that most of the peaks did not represent the target compounds. The peaks probably are associated with natural organic compounds present in the soft, organically enriched pond-bottom sediments. The presence of four explosive compounds at five widely spaced sites was confirmed by the photo-diode-array analysis, but the compounds are not generally found in contaminated ground water near the ranges. No explosives were detected in water samples obtained from the drive points. Perchlorate was detected at less than 1 microgram per liter in two drive-point samples collected at the same site on two dates about 3 months apart. The source of the perchlorate in the samples could not be related directly to other contamination from Camp Edwards with the available information. \r\n\r\nThe results from the diffusion and drive-point sampling do not indicate an area of ground-water discharge with concentrations of the ordnance-related compounds that are sufficiently elevated to be detected by these sampling methods. The diffusion and drive-point sampling data cannot be interpreted further without additional information concerning the pattern of ground-water flow at Snake Pond and the distributions of RDX, HMX, and perchlorate in ground water in the aquifer near the pond.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri034133","usgsCitation":"LeBlanc, D.R., 2003, Diffusion and drive-point sampling to detect ordnance-related compounds in shallow ground water beneath Snake Pond, Cape Cod, Massachusetts, 2001-02: U.S. Geological Survey Water-Resources Investigations Report 2003-4133, 25 p., https://doi.org/10.3133/wri034133.","productDescription":"25 p.","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":4957,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri034133/","linkFileType":{"id":5,"text":"html"}},{"id":177139,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Massachusetts ","otherGeospatial":"Cape Cod","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.7958984375,\n              41.582579601430346\n            ],\n            [\n              -69.85107421874999,\n              41.582579601430346\n            ],\n            [\n              -69.85107421874999,\n              42.21224516288584\n            ],\n            [\n              -70.7958984375,\n              42.21224516288584\n            ],\n            [\n              -70.7958984375,\n              41.582579601430346\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d69f","contributors":{"authors":[{"text":"LeBlanc, Denis R. 0000-0002-4646-2628 dleblanc@usgs.gov","orcid":"https://orcid.org/0000-0002-4646-2628","contributorId":1696,"corporation":false,"usgs":true,"family":"LeBlanc","given":"Denis","email":"dleblanc@usgs.gov","middleInitial":"R.","affiliations":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true}],"preferred":true,"id":246159,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

MeHg production potential was also greatest during this period and decreased during spring and fall. This temporal trend was related both to an increase in gross MeHg degradation, driven by increasing temperature, and to a build-up in pore water sulfide and solid phase reduced sulfur driven by increased sulfate reduction during the warmer seasons. MeHg production decreased sharply with depth at two of three sites, both of which exhibited a corresponding increase in reduced sulfur compounds with depth.

The rapid rate of economic development, demographics and poverty are believed to be the underlying forces responsible for the change. Accurate and up-to-date information to support the above statement is, however, not available. The available data, if any, are outdated and are not comparable for various technical reasons. Time series analysis of land cover change and the identification of the driving forces responsible for these changes are needed for the sustainable management of natural resources and also for projecting future land cover trajectories. We analysed the multi-temporal and multi-seasonal NOAA Advanced Very High Resolution Radiometer (AVHRR) satellite data of 1985/86 and 1992 to (1) prepare historical land cover maps and (2) to identify areas undergoing major land cover transformations (called &lsquo;hot spots&rsquo;). The identified &lsquo;hot spot&rsquo; areas were investigated in detail using high-resolution satellite sensor data such as Landsat and SPOT supplemented by intensive field surveys. Shifting cultivation, intensification of agricultural activities and change of cropping patterns, and conversion of forest to agricultural land were found to be the principal reasons for land use/land cover change in the Oudomxay province of Lao PDR, the Mekong Delta of Vietnam and the Loei province of Thailand, respectively. Moreover, typical land use/land cover change patterns of the &lsquo;hot spot&rsquo; areas were also examined. In addition, we developed an operational methodology for land use/land cover change analysis at the national level with the help of national remote sensing institutions.</p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/0143116031000139827","usgsCitation":"Giri, C., Defourny, P., and Shrestha, S., 2003, Land cover characterization and mapping of continental southeast Asia using multi-resolution satellite sensor data: International Journal of Remote Sensing, v. 24, no. 21, p. 4181-4196, https://doi.org/10.1080/0143116031000139827.","productDescription":"16 p.","startPage":"4181","endPage":"4196","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":307055,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"21","noUsgsAuthors":false,"publicationDate":"2010-06-07","publicationStatus":"PW","scienceBaseUri":"55d6fa34e4b0518e3546bc4d","contributors":{"authors":[{"text":"Giri, Chandra cgiri@usgs.gov","contributorId":2403,"corporation":false,"usgs":true,"family":"Giri","given":"Chandra","email":"cgiri@usgs.gov","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":569014,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Defourny, Pierre","contributorId":146809,"corporation":false,"usgs":false,"family":"Defourny","given":"Pierre","email":"","affiliations":[],"preferred":false,"id":569015,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Shrestha, Surendra","contributorId":145742,"corporation":false,"usgs":false,"family":"Shrestha","given":"Surendra","email":"","affiliations":[],"preferred":false,"id":569016,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Few long-term, continuous-record streamflow-gaging stations with small drainage areas were available from which to develop the equations; therefore, 24 partial-record gaging stations were established in this investigation. A mathematical technique for estimating a standard low-flow statistic, August median streamflow, at partial-record stations was applied by relating base-flow measurements at these stations to concurrent daily flows at nearby long-term, continuous-record streamflow- gaging stations (index stations). Generalized least-squares regression analysis (GLS) was used to relate estimates of August median streamflow at gaging stations to basin characteristics at these same stations to develop equations that can be applied to estimate August median streamflow on ungaged streams. GLS accounts for varying periods of record at the gaging stations and the cross correlation of concurrent streamflows among gaging stations. Twenty-three partial-record stations and one continuous-record station were used for the final regression equations.\r\n\r\nThe basin characteristics of drainage area and mean basin elevation are used in the calculated regression equation for ungaged streams to estimate August median flow. The equation has an average standard error of prediction from -38 to 62 percent. A one-variable equation uses only drainage area to estimate August median streamflow when less accuracy is acceptable. This equation has an average standard error of prediction from -40 to 67 percent. Model error is larger than sampling error for both equations, indicating that additional basin characteristics could be important to improved estimates of low-flow statistics. \r\n\r\nWeighted estimates of August median streamflow, which can be used when making estimates at partial-record or continuous-record gaging stations, range from 0.03 to 11.7 cubic feet per second or from 0.1 to 0.4 cubic feet per second per square mile. Estimates of August median streamflow on ungaged streams in the eastern part of Aroostook County, within the range of acceptable explanatory variables, range from 0.03 to 30 cubic feet per second or 0.1 to 0.7 cubic feet per second per square mile. Estimates of August median streamflow per square mile of drainage area generally increase as mean elevation and drainage area increase.","language":"ENGLISH","doi":"10.3133/wri034225","usgsCitation":"Lombard, P., Tasker, G.D., and Nielsen, M.G., 2003, August Median Streamflow on Ungaged Streams in Eastern Aroostook County, Maine: U.S. Geological Survey Water-Resources Investigations Report 2003-4225, 20 p., https://doi.org/10.3133/wri034225.","productDescription":"20 p.","costCenters":[],"links":[{"id":179355,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":5125,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri034225/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4ce4b07f02db626368","contributors":{"authors":[{"text":"Lombard, Pamela J. 0000-0002-0983-1906","orcid":"https://orcid.org/0000-0002-0983-1906","contributorId":23899,"corporation":false,"usgs":true,"family":"Lombard","given":"Pamela J.","affiliations":[],"preferred":false,"id":246388,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tasker, Gary D.","contributorId":95035,"corporation":false,"usgs":true,"family":"Tasker","given":"Gary","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":246389,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nielsen, Martha G. 0000-0003-3038-9400 mnielsen@usgs.gov","orcid":"https://orcid.org/0000-0003-3038-9400","contributorId":4169,"corporation":false,"usgs":true,"family":"Nielsen","given":"Martha","email":"mnielsen@usgs.gov","middleInitial":"G.","affiliations":[{"id":37947,"text":"Upper Midwest Water Science Center","active":true,"usgs":true}],"preferred":true,"id":246387,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The majority of the mills and tailings sites are not recorded in the literature. All tailings impoundments show evidence of substantial amounts of erosion.\r\nAt least 11 tailings dams were breached by flood waters, carrying fluvial tailings 1 to 15 km down canyons and across alluvial fans. Most of the tailings sites are dry most of the year, but some are near streams. Tailings that are wet for part of the year do not appear to be reacting significantly with those waters because physical factors such as clay layers and hard-pan cement appear to limit permeability and release of metals to surface waters. The major impact of mill tailings on surface-\r\nwater quality may be brief flushes of runoff during storm events that carry acid and metals released from soluble mineral crusts. Small ephemeral ponds and puddles that tend to collect in trenches and low areas on tailings impoundments tend to be acidic and extremely enriched in metals, in part through cycles of evaporation. Ponded water that is rich in salts and metals could be acutely toxic to unsuspecting animals. Rare extreme storms have the potential to cause catastrophic failure of tailings\r\nimpoundments, carry away metals in stormwaters, and transport tailings as debris flows for 1 to 15 km. In most situations\r\nthese stormwaters and transported tailings could impact wildlife but probably would impact few or no people or domes-tic water wells. Because all identified historic tailings sites are several kilometers or more from the Humboldt River and major tributaries, tailings probably have no measurable impact on water quality in the main stem of the Humboldt River.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Geoenvironmental investigations of the Humboldt River basin, northern Nevada","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/b2210D","usgsCitation":"Nash, J.T., and Stillings, L., 2003, Historic mills and mill tailings as potential sources of contamination in and near the Humboldt River basin, northern Nevada (Version 1.0): U.S. Geological Survey Bulletin 2210, vi, 36 p., https://doi.org/10.3133/b2210D.","productDescription":"vi, 36 p.","temporalStart":"1995-01-01","temporalEnd":"2000-12-31","costCenters":[],"links":[{"id":177997,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":390441,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_61751.htm"},{"id":4767,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/bul/b2210-d/","linkFileType":{"id":5,"text":"html"}}],"scale":"0","country":"United States","state":"Nevada","otherGeospatial":"Humboldt River basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -119,\n              39.1667\n            ],\n            [\n              -115,\n              39.1667\n            ],\n            [\n              -115,\n              42\n            ],\n            [\n              -119,\n              42\n            ],\n            [\n              -119,\n              39.1667\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a58e4b07f02db62ed70","contributors":{"authors":[{"text":"Nash, J.

They are concerned that pumping of water from the N aquifer will induce leakage from the overlying D aquifer, resulting in the degradation of water quality in the N aquifer. Water samples from the D aquifer contained higher concentrations of dissolved solids than samples from the N aquifer; however, ground waters in the D and N aquifers evolve similarly along their respective flow paths.\r\n\r\nThe ground-water composition in the D aquifer results from interaction with limestone and sandstone sediments. The ground water evolves from a calcium magnesium bicarbonate type in the recharge area to a sodium bicarbonate type in downgradient areas. 34S data indicate sulfate reduction occurs when ground water comes in contact with lignite seams in the Dakota Sandstone. Adjusted 14C ages for ground water in the D aquifer range from 4,000 to 33,000 years. d18O and d2H data indicate that most of the recharge occurred when the climate was cooler and more humid than at present. 3H data indicate that localized recharge has occurred in some areas in recent time.\r\n\r\nLeakage between the D and N aquifers has been occurring for thousands of years. The area of highest leakage occurs in the southern areas of Black Mesa, where the N aquifer is thin, the predevelopment hydraulic gradient is small, and the vertical head differences between the D and N aquifers are small. Induced leakage from ground-water development in the last several decades could take centuries to detect geochemically because of the increased vertical difference between the potentiometric surfaces of the D and N aquifers, and possibly because of increases in the hydraulic gradient in the N aquifer that would increase flow rates, causing dilution.\r\n\r\n87Sr/86Sr data are consistent with the leakage of ground water from the D aquifer into the N aquifer in the southern part of Black Mesa. 87Sr/86Sr values for the N and D aquifers are similar in this area; statistical means are -2.74 ? and -2.49 ?, respectively, N aquifer 87Sr/86Sr values are more radiogenic than D aquifer values in the northern part of Black Mesa; statistical means are -0.14 ? and -2.49 ?, respectively.","language":"ENGLISH","doi":"10.3133/wri034189","usgsCitation":"Truini, M., and Longsworth, S.A., 2003, Hydrogeology of the D aquifer and movement and ages of ground water determined from geochemical and isotopic analyses, Black Mesa area, northeastern Arizona: U.S. Geological Survey Water-Resources Investigations Report 2003-4189, vi, 38 p. : ill.

Although\r\nseveral total petroleum systems may exist in the province,\r\nonly one composite total petroleum system, the Cretaceous-Tertiary Composite Total Petroleum System, was defined\r\nwith one assessment unit, the Coastal Plain and Offshore Assessment Unit, having sufficient data to allow quantitative assessment.\r\nThe primary source rocks for the Cretaceous-Tertiary Composite Total Petroleum System are the Cenomanian-Turonian marine shales. The Turonian shales can be as much\r\nas 150 meters thick and contain Type II organic carbon ranging from 3 to 10 weight percent. In the Senegal Province, source rocks are mature even when situated at depths relatively shallow\r\nfor continental passive margin basins. Reservoir rocks consist\r\nof Upper Cretaceous sandstones and lower Tertiary clastic and carbonate rocks. The Lower Cretaceous platform carbonate rocks (sealed by Cenomanian shales) have porosities ranging from 10 to 23 percent. Oligocene carbonate rock reservoirs exist, such as the Dome Flore field, which contains as much\r\nas 1 billion barrels of heavy oil (10? API, 1.6 percent sulfur)\r\nin place. The traps are a combination of structural closures\r\nand stratigraphic pinch-outs.\r\nHydrocarbon production in the Senegal Province to date has been limited to several small oil and gas fields around\r\nCape Verde (also known as the Dakar Peninsula) from Upper Cretaceous sandstone reservoirs bounded by normal faults, of which three fields (two gas and one oil) exceed the minimum size assessed in this study (1 MMBO; 6 BCFG).

This report describes a study to evaluate the effect these disturbances have had on stream channels in eastern Nebraska. \r\n\r\nTwo sets of survey data were collected approximately 2 years apart during 1996-99 at 151 primary sites. Additionally, historical streambed-elevation data (dating back to the 1890s) were compiled from several sources for the primary sites and 45 supplemental sites, and relevant disturbances were identified for each of eight basin groupings. Streambed-elevation data sets were used to estimate the amount of change to the streambed at the sites over the time period of the data. Recent channel widening was documented for 73 of the primary sites by comparing the two survey sets.\r\n\r\nThe majority of observed streambed-gradation responses appear to be related to the various straightening efforts and to the effects of grade-control structures in the study area. Channel responses were complicated by the presence of multiple disturbances. However, in many cases, the streambed-elevation data sets provide a reliable representation of the past streambed gradation, with some sites showing 6 to 7 meters of degradation since they were straightened. Many sites that had been straightened showed considerable degradation following the disturbance. This indicates that eastern Nebraska stream channels can regain equilibrium mainly through the slope adjustment process of head-ward-progressing degradation.\r\n\r\nBank failures were documented at sites in all eight of the basin groupings analyzed, and widening rates were computed at 64 of 73 sites. Observed bank widening in the Big Blue River Basin, a relatively unstraightened basin, indicates that other disturbances besides stream-channel straightening may be causing channel responses in the basin and possibly in the entire study area.","language":"ENGLISH","doi":"10.3133/wri034003","usgsCitation":"Rus, D.L., Dietsch, B.J., and Simon, A., 2003, Streambed adjustment and channel widening in eastern Nebraska: U.S. Geological Survey Water-Resources Investigations Report 2003-4003, 63 p., 34 figs., https://doi.org/10.3133/wri034003.","productDescription":"63 p., 34 figs.","costCenters":[],"links":[{"id":4570,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri034003/","linkFileType":{"id":5,"text":"html"}},{"id":178254,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a4f77","contributors":{"authors":[{"text":"Rus, David L. 0000-0003-3538-7826 dlrus@usgs.gov","orcid":"https://orcid.org/0000-0003-3538-7826","contributorId":881,"corporation":false,"usgs":true,"family":"Rus","given":"David","email":"dlrus@usgs.gov","middleInitial":"L.","affiliations":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true}],"preferred":true,"id":242303,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dietsch, Benjamin J. 0000-0003-1090-409X bdietsch@usgs.gov","orcid":"https://orcid.org/0000-0003-1090-409X","contributorId":1346,"corporation":false,"usgs":true,"family":"Dietsch","given":"Benjamin","email":"bdietsch@usgs.gov","middleInitial":"J.","affiliations":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true}],"preferred":true,"id":242304,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Simon, Andrew","contributorId":78334,"corporation":false,"usgs":true,"family":"Simon","given":"Andrew","email":"","affiliations":[],"preferred":false,"id":242305,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Data for this study were obtained from about 2,100 surface- and ground-water samples that were analyzed for Kjeldahl nitrogen and Kjeldahl phosphorus in the course of routine operations at the USGS National Water Quality Laboratory (NWQL). These samples were analyzed independently for total nitrogen and total phosphorus using an alkaline persulfate digestion method developed by the NWQL Methods Research and Development Program. About half of these samples were collected during nominally high-flow (April-June) conditions and the other half were collected during nominally low-flow (August-September) conditions. The number of filtered and whole-water samples analyzed from each flow regime was about equal.By operational definition, Kjeldahl nitrogen (ammonium + organic nitrogen) and alkaline persulfate digestion total nitrogen (ammonium + nitrite + nitrate + organic nitrogen) are not equivalent. It was necessary, therefore, to reconcile this operational difference by subtracting nitrate + nitrite concentra-tions from alkaline persulfate dissolved and total nitrogen concentrations prior to graphical and statistical comparisons with dissolved and total Kjeldahl nitrogen concentrations. On the basis of two-population paired t-test statistics, the means of all nitrate-corrected alkaline persulfate nitrogen and Kjeldahl nitrogen concentrations (2,066 paired results) were significantly different from zero at the p = 0.05 level. Statistically, the means of Kjeldahl nitrogen concentrations were greater than those of nitrate-corrected alkaline persulfate nitrogen concentrations. Experimental evidence strongly suggests, however, that this apparent low bias resulted from nitrate interference in the Kjeldahl digestion method rather than low nitrogen recovery by the alkaline persulfate digestion method. Typically, differences between means of Kjeldahl nitrogen and nitrate-corrected alkaline persulfate nitrogen in low-nitrate concentration (< 0.1 milligram nitrate nitrogen per liter) subsets of filtered surface- and ground-water samples were statistically equivalent to zero at the\r\np =level.Paired analytical results for dissolved and total phosphorus in Kjeldahl and alkaline persulfate digests were directly comparable because both digestion methods convert all forms of phosphorus in water samples to orthophosphate. On the basis of two-population paired t-test statistics, the means of all Kjeldahl phosphorus and alkaline persulfate phosphorus concentrations (2,093 paired results) were not significantly different from zero at the p = 0.05 level. For some subsets of these data, which were grouped according to water type and flow conditions at the time of sample collection, differences between means of Kjeldahl phosphorus and alkaline persulfate phosphorus concentrations were not equivalent to zero at the p = 0.05 level. Differences between means of these subsets, however, were less than the method detection limit for phosphorus (0.007 milligram phosphorus per liter) by the alkaline persulfate digestion method, and were therefore analytically insignificant.This report provides details of the alkaline persulfate digestion procedure, interference studies, recovery of various nitrogen- and phosphorus-containing compounds, and other analytical figures of merit. The automated air-segmented continuous flow methods developed to determine nitrate and orthophosphate in the alkaline persulfate digests also are described.

Continuous monitoring data indicated that each spring responds differently to storms. Water quality and discharge at Wilson Spring, which is located in the Central Basin karst region of Tennessee, changed rapidly after rainfall. Water quality and discharge also varied at Cascade Spring; however, changes did not occur as frequently or as quickly as changes at Wilson Spring. Water quality and discharge at Big Spring at Rutledge Falls changed little in response to storms. Cascade Spring and Big Spring at Rutledge Falls are located in similar hydrogeologic settings on the escarpment of the Highland Rim. \r\n\r\nNonisokinetic dip-sampling methods were used to collect VOC samples from the springs during base-flow conditions. During selected storms, automatic samplers were used to collect water samples at Cascade Spring and Wilson Spring. Water samples were collected as frequently as every 15 minutes at the beginning of a storm, and sampling intervals were gradually increased following a storm. VOC samples were analyzed using a portable gas chromatograph (GC). VOC samples were collected from Wilson, Cascade, and Big Springs during 600, 199, and 55 sampling times, respectively, from February 2000 to May 2001. \r\n\r\nChloroform concentrations detected at Wilson Spring ranged from 0.073 to 34 mg/L (milligrams per liter).

Concentrations of cis-1,2-dichloroethylene (cis-1,2-DCE) detected at Cascade Spring ranged from 0.30 to 1.8 ?g/L (micrograms per liter) and gradually decreased between November 2000 and May 2001. In addition to the gradual decrease in cis-1,2-DCE concentrations, some additional decreases were detected during storms. VOC samples collected at weekly intervals from Big Spring indicated a gradual decrease in trichloroethylene (TCE) concentrations from approximately 9 to 6 ?g/L between November 2000 and May 2001. Significant changes in TCE concentrations were not detected during individual storms at Big Spring. \r\n\r\nQuality-control samples included trip blanks, equipment blanks, replicates, and field-matrix spike samples. VOC concentrations measured using the portable GC were similar to concentrations in replicate samples analyzed by the USGS National Water Quality Laboratory (NWQL) with the exception of chloroform and TCE concentrations. Chloroform and TCE concentrations detected by the portable GC were consistently lower (median percent differences of ?19.2 and ?17.4, respectively) than NWQL results. High correlations, however, were observed between concentrations detected by the portable GC and concentrations detected by the NWQL (Pearson?s r > 0.96). VOC concentrations in automatically collected samples were similar to concentrations in replicates collected using dip-sampling methods. More than 80 percent of the VOC concentrations measured in automatically collected samples were within 12 percent of concentrations in dip samples.","language":"ENGLISH","doi":"10.3133/ofr03355","usgsCitation":"Williams, S.D., and Farmer, J., 2003, Volatile organic compound data from three karst springs in middle Tennessee, February 2000 to May 2001: U.S. Geological Survey Open-File Report 2003-355, 69 p., https://doi.org/10.3133/ofr03355.","productDescription":"69 p.","costCenters":[],"links":[{"id":4666,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr03355/","linkFileType":{"id":5,"text":"html"}},{"id":175260,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49abe4b07f02db5c5a4d","contributors":{"authors":[{"text":"Williams, Shannon D. swilliam@usgs.gov","contributorId":4133,"corporation":false,"usgs":true,"family":"Williams","given":"Shannon","email":"swilliam@usgs.gov","middleInitial":"D.","affiliations":[{"id":24708,"text":"Lower Mississippi-Gulf Water Science Center","active":true,"usgs":true}],"preferred":true,"id":246652,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Farmer, James","contributorId":37407,"corporation":false,"usgs":true,"family":"Farmer","given":"James","email":"","affiliations":[],"preferred":false,"id":246653,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In the Nelson area, rocks ranging in age from Middle Proterozoic through Cretaceous are exposed on three major thrust plates in which rocks have been telescoped eastward. Rocks within the thrust plates are folded and broken by thrust faults of smaller displacement than the major bounding thrust faults. Middle and Late Tertiary sedimentary and volcaniclastic rocks unconformably overlie the pre-Tertiary rocks. A major normal fault displaces rocks of the western half of the quadrangle down on the west with respect to strata of the eastern part. Alluvial and terrace gravels and local landslide deposits are present in valley bottoms and on canyon walls in the deeply dissected terrain.\r\n      Different stratigraphic successions are exposed at different structural levels across the quadrangle.  In the northeastern part, strata of the Middle Cambrian Flathead Sandstone, Wolsey Shale, and Meagher Limestone, the Middle and Upper Cambrian Pilgrim Formation and Park Shale undivided, the Devonian Maywood, Jefferson, and lower part of the Three Forks Formation, and Lower and Upper Mississippian rocks assigned to the upper part of the Three Forks Formation and the overlying Lodgepole and Mission Canyon Limestones are complexly folded and faulted. These deformed strata are overlain structurally in the east-central part of the quadrangle by a succession of strata including the Middle Proterozoic Greyson Formation and the Paleozoic succession from the Flathead Sandstone upward through the Lodgepole Limestone. In the east-central area, the Flathead Sandstone rests unconformably on the middle part of the Greyson Formation. The north edge, northwest quarter, and south half of the quadrangle are underlain by a succession of rocks that includes not only strata equivalent to those of the remainder of the quadrangle, but also the Middle Proterozoic Newland, Greyson, and Spokane Formations, Pennsylvanian and Upper Mississippian Amsden Formation and Big Snowy Group undivided, the Permian and Pennsylvanian Phosphoria and Quadrant Formations undivided, the Jurassic Ellis Group and Lower Cretaceous Kootenai Formation. Hornblende diorite sills and irregular bodies of probable Late Cretaceous age intrude Middle Proterozoic, Cambrian and Devonian strata. No equivalent intrusive rocks are present in structurally underlying successions of strata. In this main part of the quadrangle, the Flathead Sandstone cuts unconformably downward from south to north across the Spokane Formation into the upper middle part of the Greyson Formation. Tertiary (Miocene?) strata including sandstone, pebble and cobble conglomerate, and vitric crystal tuff underlie, but are poorly exposed, in the southeastern part of the quadrangle where they are overlain by late Tertiary and Quaternary gravel.\r\n      The structural complexity of the quadrangle decreases from northeast to southwest across the quadrangle. At the lowest structural level (Avalanche Butte thrust plate) exposed in the canyon of Beaver Creek, lower and middle Paleozoic rocks are folded in northwest-trending east-inclined disharmonic anticlines and synclines that are overlain by recumbently folded and thrust faulted Devonian and Mississippian rocks. The Mississippian strata are imbricated adjacent to the recumbent folds. In the east-central part of the quadrangle, a structurally overlying thrust plate, likely equivalent to the Hogback Mountain thrust plate of the Hogback Mountain quadrangle adjacent to the east (Reynolds, 20xx), juxtaposes recumbently folded Middle Proterozoic and unconformably overlying lower Paleozoic rocks on the complexly folded and faulted rocks of the Avalanche Butte thrust plate.

Streams in this watershed drain\nthe northern flank of the Coeur d’Alene mining district,\none of the world’s largest producers of silver and one\nof the country’s major historical producers of lead and\nzinc for more than 100 years. Effective cleanup of\nthese streams will depend on accurate characterization\nof metal concentrations in streams and various sources\nof these metals.\nCadmium, lead, and zinc loads entering Beaver\nCreek and its major tributary, Carbon Creek, were\nquantified, and source areas for these metals were\nassessed during May and June 2002. Metal loads were\ncalculated for main-stem and surface-inflow sites by\ncombining measured streamflow with dissolved cadmium,\nlead, and zinc concentrations analyzed in waterquality\nsamples collected during three synoptic sampling\nevents. To assess the effects of surface and shallow\nsubsurface inflows on the gain or loss of streamflow\nand metal loads, Beaver and Carbon Creeks were\ndivided into subreaches. Four subreaches were defined\non Beaver Creek using five main-stem sampling sites\n(UBC3, UBC5, UBC8, BC10, and BC14); two subreaches\nwere defined on Carbon Creek using three\nmain-stem sampling sites (CC2, CC6, and CC9).\nDuring each of the synoptic sampling events, concentrations\nof cadmium and zinc were highest in samples\ncollected at the Carlisle Mine adit between sites\nCC2 and CC6. During two of the three synoptic sampling\nevents, the concentration of lead was highest in\nsamples collected from a left-bank seep downgradient\nfrom the Idora Mill between sites UBC3 and UBC5.\nThe largest identified cadmium and zinc source to\nBeaver Creek is the surface inflow from Carbon Creek\n(between sites UBC8 and BC10), which accounted for\n45 to 72 percent of the main-stem cadmium load and\n49 to 89 percent of the main-stem zinc load in Beaver\nCreek. Another large source of cadmium and zinc to\nBeaver Creek is subsurface flow through the tiered\nflotation tailings pile near Carbon Center (between\nsites BC10 and BC14) into Beaver Creek.\nAmounts of lead contributed by source areas to\nBeaver Creek vary with streamflow conditions. During\nhigh streamflow, the largest source of lead to Beaver\nCreek is the remobilization of fine-grained (less than\n0.45-micrometer), lead-enriched particulates from the\nstreambed throughout the study area. During low\nstreamflow, bank seepage of subsurface water into\nBeaver Creek in the subreach downgradient from the\nIdora Mill (between sites UBC3 and UBC5) is the\nmajor source of lead to Beaver Creek. During each\nsynoptic sampling event, Carbon Creek is a major\nsource of lead to Beaver Creek.\nThe Carlisle Mine adit (between CC2 and CC6)\nis the largest source of cadmium and zinc to Carbon\nCreek and, ultimately, to Beaver Creek, and accounted\nfor 57 to 88 percent of the total main-stem cadmium\nload and 56 to 88 percent of the total main-stem zinc\nload in Carbon Creek during each of the synoptic sampling\nevents. Another source of cadmium and zinc to\nCarbon Creek is resurfacing cadmium- and zincenriched\nhyporheic flow (possibly originating from\nthe Carlisle adit or the Carlisle Mill) between sites\nCC6 and CC9.\nAs in Beaver Creek, amounts of lead contributed\nto Carbon Creek by source areas vary with streamflow\nconditions. During high streamflows, increased discharge\nfrom the Carlisle Mine adit appears to be the\nlargest source of lead to Carbon Creek; during low\nstreamflows, resurfacing lead-enriched hyporheic flow\nappears to be the major source of lead to Carbon Creek.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri034206","collaboration":"Prepared in cooperation with U.S. Forest Service and Bureau of Land Management","usgsCitation":"Ott, D.S., and Clark, D.W., 2003, Quantification of metal loads and assessment of metal sources in upper Beaver Creek watershed, Shoshone County, Idaho, May and June 2002: U.S. Geological Survey Water-Resources Investigations Report 2003-4206, iv, 32 p., https://doi.org/10.3133/wri034206.","productDescription":"iv, 32 p.","numberOfPages":"38","temporalStart":"2002-05-01","temporalEnd":"2002-06-30","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":262374,"rank":800,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/2003/4206/report.pdf"},{"id":262375,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/2003/4206/report-thumb.jpg"}],"country":"United States","state":"Idaho","county":"Shoshone","city":"Ferguson","otherGeospatial":"Idora Mill","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.001284,47.397354 ], [ -116.001284,47.641544 ], [ -115.598701,47.641544 ], [ -115.598701,47.397354 ], [ -116.001284,47.397354 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a87e4b07f02db64e90e","contributors":{"authors":[{"text":"Ott, Douglas S. dott@usgs.gov","contributorId":3552,"corporation":false,"usgs":true,"family":"Ott","given":"Douglas","email":"dott@usgs.gov","middleInitial":"S.","affiliations":[],"preferred":true,"id":246677,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Clark, David W.","contributorId":77146,"corporation":false,"usgs":true,"family":"Clark","given":"David","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":246678,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

During the early alkalic and shield stages, two or more elongate rift zones may develop as flanks of the volcano separate. Mantle-derived magma rises through a vertical conduit and is temporarily stored in a shallow summit reservoir from which magma may erupt within the summit region or be injected laterally into the rift zones. The ongoing activity at Kilauea's Pu?u ?O?o cone that began in January 1983 is one such rift-zone eruption. The rift zones commonly extend deep underwater, producing submarine eruptions of bulbous pillow lava.</p>\n<br/>\n<p>Once a volcano has grown above sea level, subaerial eruptions produce lava flows of jagged, clinkery ?a?a or smooth, ropy pahoehoe. If the flows reach the ocean they are rapidly quenched by seawater and shatter, producing a steep blanket of unstable volcanic sediment that mantles the upper submarine slopes. Above sea level then, the volcanoes develop the classic shield profile of gentle lava-flow slopes, whereas below sea level slopes are substantially steeper. While the volcanoes grow rapidly during the shield stage, they may also collapse catastrophically, generating giant landslides and tsunami, or fail more gradually, forming slumps. Deformation and seismicity along Kilauea's south flank indicate that slumping is occurring there today.</p>\n<br/>\n<p>Loading of the underlying Pacific Plate by the growing volcanic edifices causes subsidence, forming deep basins at the base of the volcanoes. Once volcanism wanes and lava flows no longer reach the ocean, the volcano continues to submerge, while erosion incises deep river valleys, such as those on the Island of Kaua?i.

Water samples were collected primarily from domestic wells in Texas and eastern New Mexico. Depths of wells sampled ranged from 100 to 500 feet, with a median depth of 201 feet. Depths to water ranged from 34 to 445 feet below land surface, with a median depth of 134 feet. Of 240 properties or constituents measured or analyzed, 10 exceeded U.S. Environmental Protection Agency public drinking-water standards or guidelines in one or more samples - arsenic, boron, chloride, dissolved solids, fluoride, manganese, nitrate, radon, strontium, and sulfate. Measured dissolved solids concentrations in 29 samples were larger than the public drinking-water guideline of 500 milligrams per liter. Fluoride concentrations in 16 samples, mostly in the southern part of the study area, were larger than the public drinking-water standard of 4 milligrams per liter. Nitrate was detected in all samples, and concentrations in six samples were larger than the public drinking-water standard of 10 milligrams per liter. Arsenic concentrations in 14 samples in the southern part of the study area were larger than the new (2002) public drinking-water standard of 10 micrograms per liter. Radon concentrations in 36 samples were larger than a proposed public drinking-water standard of 300 picocuries per liter. Pesticides were detected at very small concentrations, less than 1 microgram per liter, in less than 20 percent of the samples. The most frequently detected compounds were atrazine and breakdown products of atrazine, a finding similar to those of National Water-Quality Assessment aquifer studies across the Nation. Four volatile organic compounds were detected at small concentrations in six water samples. About 70 percent of the 48 primarily domestic wells sampled contained some fraction of recently (less than about 50 years ago) recharged ground water, as indicated by the presence of one or more pesticides, or tritium or nitrate concentrations greater than threshold levels.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston,

The U.S. Geological Survey collected wetland sediment samples from 11 sites in the Lauderick Creek area for microbial analyses, and used existing data to evaluate biodegradation processes and rates. The bacterial and methanogen communities in the Lauderick Creek wetland sediments were similar to those observed in a previous U.S. Geological Survey study at the West Branch Canal Creek wet-land area, Aberdeen Proving Ground. Evaluation of the degradation rate of 1,1,2,2-tetrachloroethane and the daughter compounds produced also showed similar results for the two wetlands. How-ever, a vertical profile of contaminant concentra-tions in the wetlands was available at only one site in the Lauderick Creek area, and flow velocities in the wetland sediment are unknown. To better evaluate natural attenuation processes and rates in the wetland sediments at Lauderick Creek, chemi-cal and hydrologic measurements are needed along ground-water flowpaths in the wetland at additional sites and during different seasons. Nat-ural attenuation in the wetlands, enhanced biore-mediation, and constructed wetlands could be feasible remediation methods for the chlorinated volatile organic compounds discharging in the Lauderick Creek area. The similarities in the microbial communities and biodegradation pro-cesses at the Lauderick Creek and West Branch Canal Creek areas indicate that enhanced bioreme-diation techniques currently being developed for the West Branch Canal Creek wetland area would be transferable to this area.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri034119","usgsCitation":"Lorah,

The Ozark aquifer is composed of, in order of increasing age, the Cotter Dolomite, Jefferson City Dolomite, Roubidoux Formation, Gasconade Dolomite, Eminence Dolomite, and Potosi Dolomite. Sedimentary strata are nearly horizontal, except along folds and collapse zones where dips can be steep. The basin is cut by numerous faults, most of which trend generally northwest-southeast. The Jefferson City Dolomite and the Cotter Dolomite generally yield little water to wells. Wells completed in the Roubidoux Formation and Gasconade Dolomite commonly yield from several tens to several hundred gallons per minute of water. The Eminence Dolomite may form a weak hydrologic barrier to vertical ground-water flow between the overlying Gasconade Dolomite and the underlying Potosi Dolomite. The Potosi Dolomite is the most permeable formation in the Ozark aquifer. Wells completed in the Potosi Dolomite may yield from several hundred to 1,000 gallons per minute of water.\r\n\r\nWater-table contours indicate several areas of high permeability karst terrain in the upper Gasconade River Basin. Ground-water levels may be as deep as 300 feet below the land surface beneath upland areas where karst features are prevalent. Although the Jefferson City Dolomite and the Roubidoux Formation are the uppermost bedrock formations in the upland areas of the FLWMR, the water table generally is deep enough to occur in the underlying Gasconade Dolomite throughout most of the FLWMR. Discharge from springs [311 ft3/s (cubic feet per second)] represented 56 percent of the August 1999 discharge of the Gasconade River at Jerome, Missouri (552 ft3/s).\r\n\r\nFrom 1993 through 1997, annual pumpage from all public water-supply wells in the upper Gasconade River Basin ranged from 1,820 Mgal [million gallons; an average daily rate of 4.99 Mgal/d (million gallons per day)] in 1993 to 2,030 Mgal (an average daily rate of 5.56 Mgal/d) in 1997. Including an estimated 4 Mgal/d from domestic wells, the average daily pumping rate for all wells is estimated to range from 8.99 Mgal/d in 1993 to 9.56 Mgal/d in 1997. During the same period, annual pumpage from the Big Piney River, which supplies most of the water used at the FLWMR, ranged from 1,136 Mgal (an average of 3.11 Mgal/d) in 1997 to 1,334 Mgal (an average of 3.65 Mgal/d) in 1995, and as a percentage of total water use in the upper Gasconade River Basin, ranged from about 24.5 percent in 1997 to about 28.8 percent in 1993.","language":"ENGLISH","doi":"10.3133/wri034165","usgsCitation":"Mugel, D.N., and Imes, J.L., 2003, Geohydrologic framework, ground-water hydrology, and water use in the Gasconade River basin upstream from Jerome, Missouri, including the Fort Leonard Wood Military Reservation: U.S. Geological Survey Water-Resources Investigations Report 2003-4165, v, 86 p. : col. ill., maps (some col.) ; 28 cm., https://doi.org/10.3133/wri034165.","productDescription":"v, 86 p. : col. ill., maps (some col.) ; 28 cm.","costCenters":[],"links":[{"id":4787,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri034165/","linkFileType":{"id":5,"text":"html"}},{"id":174218,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1be4b07f02db6a8e79","contributors":{"authors":[{"text":"Mugel, Douglas N. dmugel@usgs.gov","contributorId":290,"corporation":false,"usgs":true,"family":"Mugel","given":"Douglas","email":"dmugel@usgs.gov","middleInitial":"N.","affiliations":[{"id":396,"text":"Missouri Water Science Center","active":true,"usgs":true}],"preferred":true,"id":246871,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Imes, Jeffrey L. jimes@usgs.gov","contributorId":2983,"corporation":false,"usgs":true,"family":"Imes","given":"Jeffrey","email":"jimes@usgs.gov","middleInitial":"L.","affiliations":[],"preferred":true,"id":246872,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
