This belt, which is about 50 miles long, extends from the region just west of Boulder southwestward across the Front Range. From 1859, when placer gold was discovered in Idaho Springs and lode gold in Central City, through 1959, ores valued at about <span>$</span>200 million were shipped from a 50-square-mile area that includes the Idaho Springs and adjacent districts to the north, west, and southwest. The adjacent Central City district, which produced ores valued at more than <span>\\$</span>100 million, is clearly the most important district in the mineral belt. The Idaho Springs district from 1860 to 1959 produced ores valued at about $65 million, and the districts to the west and southwest produced smaller amounts. Gold has accounted for about 60 percent of the value of the ore, but in some areas silver provides the chief values, and copper, lead, and zinc add value to the ores in most areas. Mining activity in the Idaho Springs and adjacent districts was at its 'heyday' in the late 1800's, it declined sharply after 1914, it was somewhat renewed during the 1930's, and it greatly declined during World War II. In the 1950's uranium prospecting stimulated some mining activity. No uranium was produced, however, and at the close of the decade only one mine--the Bald Eagle--was being worked for its precious- and base-metal ores. In this report, 135 mines and prospects are described. The mines and prospects described are those that were accessible at the time of this study, as well as a few inaccessible properties for which some information was available. Most of the data for the inaccessible or unimportant properties were obtained from Bastin and Hill (1917) and Spurr, Garrey, and Ball (1908). The following list shows, in alphabetical order, the names of about 325 openings of mines and prospects, their coordinate location on the district map (fig. 1), the page of this report on which their description starts, and the number of the illustration, if any, referring to them.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston,

This natural phenomenon of flooding has occurred on the Delaware River in the past and will occur in the future. T' o resulting inundation of large areas can cause property damage, business losses and possible loss of life, and may result in emergency costs for protection, rescue, and salvage work. For optimum development of the river valley consistent with the flood risk, an evaluation of flood conditions is necessary. Basic data and the interpretation of the data on the regimen of the streams, particularly the magnitude of floods to be expected, the frequency of their occurrence, and the areas inundated, are essential for planning and development of flood-prone areas.</p><p>This report presents information relative to the extent, depth, and frequency of floods on the Delaware River and its tributaries in the vicinity of Belvidere, N.J. Flooding on the tributaries detailed in the report pertains only to the effect of backwater from the Delaware River. Data are presented for several past floods with emphasis given to the floods of August 19, 1955 and May 24, 1942. In addition, information is given for a hypothetical flood based on the flood of August 19, 1955 modified by completed (since 1955) and planned flood-control works.</p><p>By use of relations presented in this report the extent, depth, and frequency of flooding can be estimated for any site along the reach of the Delaware River under study. Flood data and the evaluation of the data are presented so that local and regional agencies, organizations, and individuals may have a technical basis for making decisions on the use of flood-prone areas. The Delaware River Basin Commission and the U.S. Geological Survey regard this program of flood-plain inundation studies as a positive step toward flood-damage prevention. Flood-plain inundation studies, when followed by appropriate land-use regulations, are a valuable and economical supplement to physical works for flood control, such as dams and levees. Both physical works and flood-plain regulations are included in the comprehensive plans for development of the Delaware River basin.</p><p>Recommendations for land use, or suggestions for limitations of land use, are not made herein.

The hydrologic inventory presents gains or accretions to the water supply, as inflow, equated with loss by water demands, as outflow. The difference is the ground-water storage change. Items of inflow include precipitation, surface and subsurface inflow, irrigation return, and sewage effluent. Items of outflow include surface and subsurface outflow, evapotranspiration, and water pumped for irrigation and other uses. \r\n\r\nGround-water storage changes occurred as depletions of the shallow water body beneath the eastern and central parts of the Lompoc plain and beneath the upland part of the Lompoc subarea to the north and east. The estimated annual depletion of storage averaged 3,000 acre-feet. \r\n\r\nA near balance between inflow and outflow is indicated by a calculated difference of 5,000 acre-feet of accretion and an observed depletion of ground water in storage of about 3,000 acre-feet. The difference of 8,000 acre-feet between the two values, considering the magnitude of total inflow and outflow--110,000 and 105,000 acre-feet, is not significant. For the period of inventory, more water was discharged from the basin by flow in the Santa Ynez River than by pumping from wells. \r\n\r\nThe near balance between inflow and outflow for a period of near-average climatic conditions, in general, substantiates a previous estimate that perennial pumpage is as much as about 20,000 acre-feet. However, water in storage will be depleted if the progressive change in the ratio of irrigation pumpage to other pumpage continues. Even though the hydrologic balance is maintained, changes in chemical quality of the ground water, due to recycling of irrigation water and inflow of poor-quality connate water from the consolidated rocks, indicate that chemical equilibrium has not been reached. Perennial supply under the 1957-62 conditions of inventory is estimated to be between 24,000 and 26,000 acre-feet.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr6642","usgsCitation":"Evenson, R.E., 1966, Hydrologic inventory of the Lompoc subarea, Santa Ynez River basin, Santa Barbara County, California, 1957-62: U.S. Geological Survey Open-File Report 66-42, Report: iv, 27 p.; 1 Plate: 30.86 × 18.94 inches, https://doi.org/10.3133/ofr6642.","productDescription":"Report: iv, 27 p.; 1 Plate: 30.86 × 18.94 inches","costCenters":[],"links":[{"id":110342,"rank":700,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_52174.htm","linkFileType":{"id":5,"text":"html"},"description":"52174"},{"id":86949,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1966/0042/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":86948,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1966/0042/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":173956,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1966/0042/report-thumb.jpg"}],"country":"United States","state":"California","county":"Santa Barbara County","otherGeospatial":"Santa Ynez River basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -120.66284179687499,\n              34.57895241036948\n            ],\n            [\n              -120.3387451171875,\n              34.57895241036948\n            ],\n            [\n              -120.3387451171875,\n              34.70549341022544\n            ],\n            [\n              -120.66284179687499,\n              34.70549341022544\n            ],\n            [\n              -120.66284179687499,\n              34.57895241036948\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a498c","contributors":{"authors":[{"text":"Evenson, R.

These data are provided in the form of gaging-station and other flood records and as flood profiles. Flood-frequency data are used to compute the 25- and 50-year recurrence interval discharges along the Little Sioux River from mile 24 to the Minnesota State line. The profiles of these two floods are computed and presented together with the profiles of the floods that occurred in 1965 and certain prior years. Less complete data are presented for the Ocheyedan and Maple Rivers, tributaries of the Little Sioux River.</p>\n<p>Stage and discharge tabulations at 8 gaging stations for the 1965 flood can be used for volumetric computation. The same data can also be used to determine the time the flood was above a selected stage.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Iowa City","doi":"10.3133/ofr67196","issn":"0094-9140","collaboration":"Prepared in cooperation with the Iowa State Highway Commission","usgsCitation":"Schwob, H.H., 1966, Little Sioux River Basin floods: U.S. Geological Survey Open-File Report 67-196, iv, 60 p., https://doi.org/10.3133/ofr67196.","productDescription":"iv, 60 p.","numberOfPages":"66","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":351,"text":"Iowa Water Science Center","active":true,"usgs":true}],"links":[{"id":287433,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr67196.JPG"},{"id":287431,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1967/0196/report.pdf"}],"country":"United States","state":"Iowa, Minnesota","otherGeospatial":"Little Sioux River, Maple River, Ocheyedan River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -95.0372314453125,\n              43.775060351224695\n            ],\n            [\n              -95.03173828125,\n              43.58834891179792\n            ],\n            [\n              -95.0372314453125,\n              43.32118142926663\n            ],\n            [\n              -95.0372314453125,\n              43.052833917627936\n            ],\n            [\n              -95.1416015625,\n              42.88803956056295\n            ],\n            [\n              -95.3118896484375,\n              42.87596410238254\n            ],\n            [\n              -95.4656982421875,\n              42.84375132629021\n            ],\n            [\n              -95.3778076171875,\n              42.69051116998241\n            ],\n            [\n              -95.3778076171875,\n              42.52879629320373\n            ],\n            [\n              -95.350341796875,\n              42.3016903282445\n            ],\n            [\n              -95.7513427734375,\n              42.187829010590825\n            ],\n            [\n              -95.987548828125,\n              42.05745022024682\n            ],\n            [\n              -96.207275390625,\n              42.004407212963585\n            ],\n            [\n              -96.2457275390625,\n              42.05337156043361\n            ],\n            [\n              -96.240234375,\n              42.224449701009725\n            ],\n            [\n              -96.26220703125,\n              42.391008609205045\n            ],\n            [\n              -96.26220703125,\n              42.5611728553181\n            ],\n            [\n              -96.17980957031249,\n              42.80346172417078\n            ],\n            [\n              -96.0040283203125,\n              42.92022922733792\n            ],\n            [\n              -95.877685546875,\n              42.99661231842139\n            ],\n            [\n              -95.965576171875,\n              43.12504316740127\n            ],\n            [\n              -95.888671875,\n              43.201171681272456\n            ],\n            [\n              -95.8062744140625,\n              43.26120612479979\n            ],\n            [\n              -95.811767578125,\n              43.36512572875844\n            ],\n            [\n              -95.8941650390625,\n              43.54058479482877\n            ],\n            [\n              -95.92163085937499,\n              43.69965122967144\n            ],\n            [\n              -95.811767578125,\n              43.75522505306928\n            ],\n            [\n              -95.0372314453125,\n              43.775060351224695\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a62e4b07f02db63647e","contributors":{"authors":[{"text":"Schwob, Harlan H.","contributorId":23974,"corporation":false,"usgs":true,"family":"Schwob","given":"Harlan","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":192023,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Sip,ce that time the systematic collection of streamflow data. has expanded. In 1915 the Texas Board of Water Engineers (now the Texas Water Development Board) entered into a cooperative agreement with the U. S. Geological Survey for the purpose of expanding the network of stream-gaging stations in Texas. Sites were selected for stream-gaging stations to obtain hydrologic data for water supply and flood control. Therefore, the stream-gaging stations were located principally on major streams. Today, after three-quarters of a century.of hydrologic data collection, peak discharge data on small streams are still deficient in Texas. The Geological Survey and the Texas Highway Department, therefore, have entered into a cooperative program to collect peak discharge data on small streams for the purpose of deriving flood-frequency data needed for the economical design of culverts and small bridges. </p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Austin,

Extensive land use and land-treatment changes have taken place in the 12.2-square-mile Corey Creek study basin, whereas such changes in the 10.2-square-mile Elk Run basin, which is adjacent to the northeast, have been relatively slight. Elk Run basin, which is topographically and hydrologically similar to Corey Creek basin, was used as an external control for the Corey Creek basin study. \r\n\r\nMultiple-regression analysis showed that of all the variables, runoff correlated most highly with the sediment yield of each basin. \r\n\r\nSurveys at selected cross-sections of the two streams indicated that most channel changes were in the banks rather than in the bed. At points where the stream channel slope was greater than 70 feet per mile, the average annual change in cross-sectional area at the measured ranges was less than +--2.5 square feet. Filling of the stream channel occurred where the slope was 70 feet per mile or less, and such filling was greater in Corey Creek than in Elk Run. \r\n\r\nTrend analyses of data from both basins indicated no persistent changers in quantity of runoff, precipitation, or runoff intensity (peakedness), although similar analyses indicated significant changes in the rate of suspended-sediment discharge from both basins. During the period September 1957 to September 1960, sediment discharge from Corey Creek basin decreased by 11 percent relative to the sediment discharge from Elk Run. All, or most, of this decrease was the result of a decrease in sediment discharge during the May to October growing seasons. No significant trends were detected in data collected d-ring the November to April dormant season. \r\n\r\nA factor, termed the relative erosion potential, was formulated for evaluating the effects of changes in the hydrologic cover conditions. This factor was adjusted for- the effects of diversion terrace construction in the Corey Creek basin. A rank correlation test of the adjusted relative erosion potential versus the growing season Corey Creek-Elk Run suspended-sediment discharge ratio resulted in a correlation coefficient, r=0.71, significant at the 3 percent level. The least-squares regression equation derived from the .same data. was Y=0.276 X - 6.89. \r\n\r\nwhere Y was the Corey Creek-Elk Run sediment-discharge ratio and X was the adjusted relative erosion potential. The correlation coefficient was 0.65. significant at the 12 percent level. Standard error of estimate was 0.44. or about ?20 percent of the observed variation in the sediment-discharge ratio.","language":"English","publisher":"U.S. Government Printing Office","doi":"10.3133/wsp1532C","usgsCitation":"Jones, B.L., 1966, Effects of agricultural conservation practices on the hydrology of Corey Creek basin, Pennsylvania, 1954-60: U.S. Geological Survey Water Supply Paper 1532, v, 55 p. :ill. ;24 cm., https://doi.org/10.3133/wsp1532C.","productDescription":"v, 55 p. :ill. ;24 cm.","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":27395,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/1532c/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":138483,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/1532c/report-thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4ae4b07f02db624b61","contributors":{"authors":[{"text":"Jones, Benjamin L.","contributorId":78313,"corporation":false,"usgs":true,"family":"Jones","given":"Benjamin","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":144491,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The western part of the county is in the Bighorn Mountains, and the eastern part is in the Powder River structural basin. Principal streams are the Powder and Tongue Rivers, which are part of the Yellowstone River system. The climate is semiarid, and the mean annual precipitation at Sheridan is about 16 inches. \r\n\r\nRocks of Precambrian age are exposed in the central part of the Bighorn Mountains, and successively younger rocks are exposed eastward. Rocks of Tertiary age, which are the most widespread, are exposed throughout a large part of the Powder River structural basin. Deposits of Quaternary age underlie the flood plains and terraces along the larger streams, particularly in the western part of the basin. \r\n\r\nAquifers of pre-Tertiary age are exposed in the western part of the county, but they dip steeply and are deeply buried just a few miles east of their outcrop. Aquifers that might yield large supplies of water include the Bighorn Dolomite, Madison Limestone, Amsden Formation, and Tensleep Sandstone. The Flathead Sandstone, Sundance Formation, Morrison Formation, Cloverly Formation,. Newcastle Sandstone, Frontier Formation, Parkman Sandstone, Bearpaw Shale, .and Lance Formation may yield small or, under favorable conditions, moderate supplies of water. \r\n\r\nFew wells tap aquifers of pre-Tertiary age, and these are restricted to the outcrop area. The meager data available indicate that the water from the Lance Formation, Bearpaw Shale, Parkman Sandstone, Tensleep Sandstone and Amsden Formation, and Flathead Standstone is of suitable quality for domestic or stock purposes, and that water from the Tensleep Sandstone and Amsden Formation and the Flathead Sandstone is of good quality for irrigation. Samples could not be obtained from other aquifers of pre-Tertiary age; so the quality of water in these aquifers could not be determined. \r\n\r\nAdequate supplies of ground water for stock or domestic use can be developed throughout much of the report area from the Fort Union and Wasatch Formations of Tertiary age; larger supplies might be obtained from the coarse-grained sandstone facies of the Wasatch Formation near Moncreiffe Ridge. Four aquifer tests were made at wells tapping formations of Tertiary age, and the coefficients of permeability determined ranged from 2.5 to 7.9 gallons per day per square foot. The depths to which wells must be drilled to penetrate an aquifer differ within relatively short distances because of the lenticularity of the aquifers. Water in aquifers of Tertiary age may occur under water-table, artesian, or a combination of artesian and gas-lift conditions. \r\n\r\nWater from the Fort Union is usable for domestic purposes, but the iron and dissolved-solids content impair the quality at some localities. Water from the Fort Union Formation is not recommended for irrigation because of sodium and bicarbonate content. The water is regarded as good to fair for stock use. Water from the Wasatch Formation generally contains dissolved solids in excess of the suggested domestic standards, but this water is usable in the absence of other supplies. The development of irrigation supplies from the Wasatch Formation may be possible in some areas, but the water quality should be carefully checked. Water of good to very poor quality for stock supplies is obtained, depending upon the location. Hydrogen sulfide, commonly present in water of the Fort Union and Wasatch Formations, becomes an objectionable characteristic when the water is used for human consumption. \r\n\r\nDeposits of Quaternary age generally yield small to moderate supplies of water to wells. Two pumping tests were conducted, and the coefficients of permeability of the aquifers tested were 380 and 1,100 gallons per day per square foot. Usable supplies of ground water can be developed from the deposits of Quaternary age, principally along the valleys of perennial strea","language":"ENGLISH","publisher":"U. S. Govt. Print.

Many hydrologic data that aided water users in the past can be applied to present water problems and will be helpful for solving many similar problems in the future. Most of the water problems of Louisville, a water-rich area, concern management and are associated with the distribution of supplies, the quality of water, drainage, and waste disposal. \r\n\r\nThe local hydrologic system at Louisville is dominated by the Ohio River and the glacial-outwash deposits beneath its flood plain. The water-bearing limestones in the uplands are ,secondary sources of water. The average flow of the Ohio River at Louisville, 73 billion gallons per day, and the potential availability of 370 million gallons per day of ground water suitable for industrial cooling purposes minimize the chance of acute water shortage in the area. Under current development, use of water averages about 211 million gallons per day, excluding about 392 million gallons of Ohio River water circulated daily through steampower plants and returned directly to the river. Optimum use and control of the water resources will be dependent on solving several water problems. The principal sources of water are in the Ohio River bottom land, whereas the new and potential centers of use are in the uplands. Either water must be piped to these new centers from the present sources or new supplies must be developed. Available data on streamflow and ground water are adequate to plan for the development of small local supplies. \r\n\r\nSince the completion of floodwalls and levees in 1953, widespread damage from flooding is a thing of the past in the Louisville area. Some local flooding of unprotected areas and of lowlands along tributary streams still takes place. The analyses of streamflow data are useful in planning for protection of these areas, but additional streamflow records and flood-area mapping are needed to best solve the problem. Droughts are a problem only to users of small water supplies in the uplands, where additional water either can be imported or developed locally. \r\n\r\nPollution and undesirable chemical quality of water for some uses are the most serious drawbacks to the optimum development of the water resources in Louisville and Jefferson County. Available chemical analyses of ground water are useful for determining its suitability for various uses, but additional data are needed to guide management decisions. Sources of contamination should be inventoried and water samples analyzed periodically to monitor changes in quality.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Contributions to the hydrology of the United States, 1965","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wsp1819C","usgsCitation":"Bell, E.A., 1966, Summary of hydrologic conditions of the Louisville area, Kentucky: U.S. Geological Survey Water Supply Paper 1819, Report: iv, 36 p.; 6 Plates: 37.50 × 19.00 inches or smaller, https://doi.org/10.3133/wsp1819C.","productDescription":"Report: iv, 36 p.; 6 Plates: 37.50 × 19.00 inches or smaller","costCenters":[],"links":[{"id":392337,"rank":9,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25021.htm"},{"id":25615,"rank":405,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1819c/plate-6.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":25614,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1819c/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":25616,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/1819c/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":25613,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1819c/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":25612,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1819c/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":25611,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1819c/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":25610,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1819c/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":137994,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/1819c/report-thumb.jpg"}],"country":"United States","state":"Kentucky","city":"Louisville","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -85.87188720703125,\n              38.005902055387054\n            ],\n            [\n              -85.51071166992188,\n              38.005902055387054\n            ],\n            [\n              -85.51071166992188,\n              38.35350340353833\n            ],\n            [\n              -85.87188720703125,\n              38.35350340353833\n            ],\n            [\n              -85.87188720703125,\n              38.005902055387054\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b04e4b07f02db69905c","contributors":{"authors":[{"text":"Bell, Edwin Allen","contributorId":84340,"corporation":false,"usgs":true,"family":"Bell","given":"Edwin","email":"","middleInitial":"Allen","affiliations":[],"preferred":false,"id":143021,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The uppermost bedrock in the basin is limestone and shale of Permian age and sandstone, shale, and limestone of Cretaceous age. Bedrock is exposed in many places in the lower one-third of the basin but elsewhere is buried beneath a thin to thick mantle of younger sediments, mostly of Quaternary age. These younger sediments are largely fluvial and eolian deposits but also include some glacial till. Consisting in large part of sand and gravel, the fluvial deposits are an important source of ground-water supplies throughout much of the upper two-thirds of the basin. Loess, an eolian deposit of clayey silt, is by far the most widespread surficial deposit. The climate is continental. Temperatures ranging from -38 ? F to 118 ? F have been recorded in the basin. Average annual precipitation as low as 10.31 and as high as 49.32 inches has been recorded. During most years in the period 1956-62, when nearly all the water-quality data were obtained, annual precipitation and annual runoff were greater than normal. Flow-duration data indicate, however, that the flow distribution for the period was near normal. The Little Blue River has the same suspended-sediment characteristics as nearly all unregulated streams in the Great Plains--a wide range in concentrations, low concentrations during low-flow periods, and high concentrations during almost all periods of significant overland runoff. The maximum instantaneous concentration normally occurs many hours before maximum water discharge during any given rise in stage; the maximum daily mean concentration during any given year normally occurs at a moderate stream stage, not during a major flood. \r\n\r\nSuspended-sediment data for Little Blue River near Deweese, Nebr., which receives drainage from the upstream third of the basin, approximately, show that during the 1!}57-61 water years concentrations of 100 ppm (parts per million) or less prevailed about 42 percent of the time and concentrations of 1,000 ppm or less prevailed about 85 percent of the time. Observed concentrations ranged from 2 to 21,000 ppm: daily mean concentrations ranged from 2 to 13,800 ppm.\r\n\r\nThe discharge-weighted suspended-sediment concentration was computed as about 2,800 ppm at Little Blue River near Deweese, about 3,300 ppm near Fairbury (Endicott), and about 3,000 ppm at Waterville. These stations receive drainage from about one-third, two-thirds, and nearly all the basin, respectively. Water-utilization problems resulting from high concentrations are not significant in the basin ; use of water from the Little Blue River is quantitatively negligible. Concentrations and, consequently, discharges of sediment are greater at a given water discharge on a rising stage than at the same discharge on the falling stage of the same runoff event. Also, a wide range in sediment discharge occurs at similar water discharges during different runoff events. Daily sediment discharges at Little Blue River near Deweese ranged from about 1,400 to 16,000 tons at daily mean water discharges of about 500 cfs (cubic feet per second) and from almost 7,500 to 28,000 tons at water discharges of about 1,000 cfs. \r\n\r\nThe estimated long-term sediment discharge at Little Blue River near Deweese is about 400,000 tons per year: near Fairbury, about 1,200,000 tons per year: and at Waterville, about 1.900,000 tons per year. The high sediment discharge from the downstream part of the basin is due to greater precipitation and runoff--not to higher concentrations of suspended sediment--in the downstream parts of the basin. \r\n\r\nNearly all the suspended sediment is silt and clay. The streambed material is mainly medium sand to gravel. The median particle size of bed material observed was about 0.73 mm near Deweese and about 0.77 mm near Fairbury. A few computations of total sediment discharge of Little Blue River near Deweese indicate that suspended-sedim","language":"ENGLISH","publisher":"U.S. G.P.O.,","doi":"10.3133/wsp1819H","usgsCitation":"Mundorff, J.C., and Waddell, K., 1966, Fluvial sediment and chemical quality of water in the Little Blue River basin, Nebraska and Kansas: U.S. Geological Survey Water Supply Paper 1819, v, 45 p. :ill., maps ;24 cm., https://doi.org/10.3133/wsp1819H.","productDescription":"v, 45 p. :ill., maps ;24 cm.","costCenters":[],"links":[{"id":137766,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/1819h/report-thumb.jpg"},{"id":28270,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/1819h/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49d6e4b07f02db5de61f","contributors":{"authors":[{"text":"Mundorff, J.
