The goal in operating these networks has been to obtain sufficient data for estimating flood frequency at ungaged sites with the equivalent accuracy expected from 10 years of observed flood records. In some areas the networks have accumulated sufficient data to satisfy these accuracy goals. A review of these networks, looking toward possible reduction of the number of gages, is now timely. Continued operation of a few selected gages may be desirable to provide a longer time-sample base for improving the flood-frequency estimating equation and(or) to expand the area over which the equations apply.</p><p>In 1974, Thomas Maddock III developed a rational method for selecting gages to be retained in a reduced hydrologic network. This method of network analysis seeks the optimum set of gages to be retained for a given level of annual operating costs with the information content of the reduced network being the factor optimized. Application of Maddock's method demonstrated that a considerable number of gages could be eliminated from a network without grossly decreasing its information content.</p><p>Maddock's method of analysis is described in detail for a hypothetical network of gages. The method also is applied to actual networks in Montana, Illinois, and Georgia.</p><p>The analysis of networks in Montana illustrates the basic approach to selecting an optimal subset from the existing set of gages. The Illinois analysis demonstrated that by retaining only 26 percent of the gages, nearly 63 percent of the original information is retained in the reduced network. Application of the procedure shows how the design of networks in Georgia may be modified because of hydrologic considerations to meet budgetary constraints.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri7530","usgsCitation":"Carrigan, P.H., and Golden, H.G., 1975, Optimizing information transfer in a stream-gaging network: U.S. Geological Survey Water-Resources Investigations Report 75-30, v, 25 p., https://doi.org/10.3133/wri7530.","productDescription":"v, 25 p.","numberOfPages":"34","costCenters":[],"links":[{"id":157924,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1975/0030/report-thumb.jpg"},{"id":349792,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1975/0030/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aefe4b07f02db69138d","contributors":{"authors":[{"text":"Carrigan, Philip Hadley Jr.","contributorId":86768,"corporation":false,"usgs":true,"family":"Carrigan","given":"Philip","suffix":"Jr.","email":"","middleInitial":"Hadley","affiliations":[],"preferred":false,"id":196506,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Golden, Harold G.","contributorId":103244,"corporation":false,"usgs":true,"family":"Golden","given":"Harold","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":196507,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The aquifer is only a few feet thick along the Fall Line, where it is near or at the surface, but it thickens and dips to the east. At Franklin where the top of the aquifer is 220 feet (67 metres) below sea level, it is about 600 feet (180 metres) thick. Thirty five miles (56 kilometres) east of Franklin, along the eastern boundary of the model area, the top is about 900 feet (270 metres) below sea level, and the thickness is estimated to be 2,000 feet (610 metres). The aquifer consists of an alternating series of permeable and semipermeable beds, which contain various mixtures of sand, gravel, silt and clay. The sediments are continental stream deposits in the western and central parts of the area, but grade to marine deposits in the eastern part. Transmissivity is zero at or near the Fall Line, and increases eastward to 19,000 cubic feet per day per foot (1,800 cubic metres per day per metre) at Franklin. Further eastward, trans-missivity probably increases slightly, but then decreases as the marine phase is reached. The aquifer is.overlain by a semiper-meable'confining layer and is underlain by relatively impermeable rocks of the pre-Cretaceous basement.</p><p>The model used is the finite-difference digital type described by Pinder (1970). Historical water levels of the aquifer were simulated from 1891 to December 1, 1972. The 1891 water-level surface was developed by running a steady-state version of the Pinder model. Simulation runs from 1891 to 1941, 1970, and 1972 are in good agreement with historical water levels. A modeling factor was used as a multiplier for varying the coefficients of transmissivity and vertical permeability of the confining layer without altering the initial (1891) surface used to start the modeling runs. This technique should be helpful in the development of other models of artesian aquifers.</p><p>Predicitive runs show that, if pumpage continues to increase as it has in the past, serious dewatering of the aquifer will occur at Franklin and possibly at other centers of increased pumpage.

Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.

The model was not fully amenable to use on Plantation Canal because: (1) it did not consider photosynthetic production, nitrification, and benthic oxygen demand as sources and sinks of oxygen; (2) the model assumptions of complete mixing, transport, and steady state were not met; and (3) the data base was inadequate because it consisted of only one set of data for each case.

The aquifers now developed are in the upper 1,000 feet of a regionally extensive series of southwesterly dipping basalt flows of the Columbia River Group. Most of the aquifers are confined. Those in the depth range of about 500 to 1,000 feet are the chief source of ground water pumped from irrigation wells. Transmissivity of these aquifers ranges from less than 2,700 feet squared per day to more than 40,000 feet squared per day, and storage coefficients range from 0.0015 to 0.006. Shallower aquifers are generally much less permeable, but they are a source of recharge to deeper aquifers with lower artesian heads; vertical leakage occurs along joints in the basalt and down uncased wells, which short circuit the aquifer system. For model analysis, the deeper, pumped aquifers were grouped and treated as a single layer with drawdown-dependent leakage from an overlying confining layer. Verification of the model was achieved primarily by closely matching observed pumpage-related head declines ranging from about 10 feet to more than 40 feet over the 4-year period from March 1967 to March 1971. \r\n\r\nProjected average annual rates of decline in the Odessa-Lind area during the 14-year period from March 1967 to March 1981 are: from 1 to 9 feet per year if pumpage is maintained at the 1970 rate of 117,000 acre-feet per year; or, from 3 to 33 feet per year if 1970 pumpage is increased to 233,000 acre-feet per year, which includes 116,000 acre-feet per year covered by water-right applications held in abeyance. In each case, projected drawdown on the northeast side of a major ground-water barrier is about double that on the southwest side because of differences in transmissivity and storage coefficient and in sources of recharge.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wsp2036","usgsCitation":"Luzier, J., and Skrivan, J.A., 1975, Digital-simulation and projection of water-level declines in basalt aquifers of the Odessa-Lind area, east-central Washington: U.S. Geological Survey Water Supply Paper 2036, iv, 48 p., https://doi.org/10.3133/wsp2036.","productDescription":"iv, 48 p.","costCenters":[],"links":[{"id":27813,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2036/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":137723,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2036/report-thumb.jpg"},{"id":413776,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25528.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Washington","otherGeospatial":"Odessa-Lind area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -119.35,\n              47.417\n            ],\n            [\n              -119.35,\n              46.906\n            ],\n            [\n              -118.333,\n              46.906\n            ],\n            [\n              -118.333,\n              47.417\n            ],\n            [\n              -119.35,\n              47.417\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64ae35","contributors":{"authors":[{"text":"Luzier, J.

As petroleum reservoirs they commonly have poor performance histories. They contain the sediments of a depositional system comprised of three closely associated depositional subenvironments: dune, interdune, and extradune. Sediments of each subenvironment have different textural properties which resulted from different depositional processes. Dune sediments are usually more porous and permeable than interdune or extradune sediments and may be better quality reservoirs than interdune or extradune sediments. Interdune sediments are here restricted to those nondune sediments deposited in the relatively flat areas between dunes. Extradune sediments (a new term) include all deposits adjacent to a dune field and are mainly subaqueous deposits. Dune sediments may be enveloped by extradune sediments as the depositional system evolves resulting in a texturally inhomogeneous reservoir having poor fluid migration properties.\r\n\r\nThis model of textural inhomogeneity in eolian blanket sandstones. was applied to the Weber (Tensleep) Sandstone in Brady, Wertz, and Lost Soldier fields, Sweetwater County, Wyoming. Data were obtained from both outcrop and subsurface and included environmental interpretation, textural analysis, and plotting of the distribution of depositional subenvironments. As predicted from the model, the texture of dune sediments in Brady field differed markedly from interdune and extradune sediments. The predicted geometric distribution of subenvironments was confirmed in Lost Soldier and Wertz fields. However, secondary cementation and fracturing there has obscured the original porosity and permeability contrasts. The porosity and permeability distribution, a characteristic depending partly on depositional processes, could impede fluid migration in the reservoir and significantly reduce recovery of hydrocarbons.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr75363","usgsCitation":"Wrucke, C.T., 1975, Lithology and chemical analyses of core and cuttings from USGS drill hole near Gold Acres, Lander County, Nevada: U.S. Geological Survey Open-File Report 75-363, 28 leaves :map ;27 cm., https://doi.org/10.3133/ofr75363.","productDescription":"28 leaves :map ;27 cm.","costCenters":[],"links":[{"id":149518,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0363/report-thumb.jpg"},{"id":45693,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0363/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db635c16","contributors":{"authors":[{"text":"Wrucke, Chester T.","contributorId":21145,"corporation":false,"usgs":true,"family":"Wrucke","given":"Chester","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":173220,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Although the Develco discriminators were designed for this application and a matching Develco compensation discriminator was purchased, effective use of this system for subtractive compensation has been blocked by the inadequate (frequency dependent) matching of the phase of the compensation signal to that of the data signal at the point compensation is carried out in the data discriminators. John Van Schaack has ameliorated the phase mismatch problem by an empirical alteration of the compensation discriminator input bandpass filter. We have selected a set (of eight) Develco discriminators and adjusted their compensation signal input levels to minimize spurious signals (noise) originating from tape speed irregularities. The sensitivity of the data discriminators was adjusted so that deviations of +125 Hz and -125 Hz produced output signals of +2.00 volts and -2.00 volts, respectively. The eight data discriminators are driven by a multiplex signal on a single tape track (subcarriers 680, 1020, 1360, 1700, 2040, 2380, 2720, and 3060 Hz). The Develco-supplied compensation discriminator requires an unmodulated 3125 Hz signal on a separate tape track.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr75663","usgsCitation":"Eaton, J.P., 1975, Notes on some experiments on the application of subtractive compensation to USGS seismic magnetic tape recording and playback systems: U.S. Geological Survey Open-File Report 75-663, ii, 36 p., https://doi.org/10.3133/ofr75663.","productDescription":"ii, 36 p.","onlineOnly":"Y","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":379,"text":"Menlo Park Science Center","active":false,"usgs":true}],"links":[{"id":142676,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_75_663.gif"},{"id":257112,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1975/0663/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afce4b07f02db6969dc","contributors":{"authors":[{"text":"Eaton, Jerry P.","contributorId":22341,"corporation":false,"usgs":true,"family":"Eaton","given":"Jerry","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":158158,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

A 25-year period from 1949 through 1973 was simulated using monthly time intervals. Based on this simulation, it is concluded that (1) the proposed change in water use would be adequate to maintain a permanent pool of the proposed size, (2) surface-water diversions by most other canals in the study area would increase slightly under the proposed plan, (3) the flow of the Arkansas River at the Colorado-Kansas State line would increase slightly under the proposed plan, and (4) the ground-water system would not be significantly affected by the proposed change in water-use plan.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr75214","collaboration":"Prepared in cooperation with the Colorado Water Conservation Board","usgsCitation":"Luckey, R.R., 1975, Hydrologic effects of reducing irrigation to maintain a permanent pool in John Martin Reservoir, Arkansas River Valley, Colorado: U.S. Geological Survey Open-File Report 75-214, iv, 13 p., https://doi.org/10.3133/ofr75214.","productDescription":"iv, 13 p.","costCenters":[],"links":[{"id":148982,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0214/report-thumb.jpg"},{"id":346207,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0214/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Colorado","otherGeospatial":"Arkansas River Valley, John Martin Reservoir","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-102.7445,37.6428],[-103.0766,37.6417],[-103.183,37.6424],[-103.2917,37.6426],[-103.4039,37.6423],[-103.5092,37.6432],[-103.5778,37.6432],[-103.6016,37.6437],[-103.8109,37.644],[-103.8929,37.644],[-103.9661,37.6439],[-104.0591,37.6436],[-104.0597,37.7316],[-104.3518,37.8148],[-104.3889,37.8248],[-104.4978,37.8556],[-104.6074,37.886],[-104.6527,37.8982],[-104.7175,37.8949],[-104.9375,37.8834],[-104.9545,37.8822],[-104.9737,37.881],[-105.0017,37.8794],[-105.0041,37.8794],[-105.0093,37.879],[-105.0122,37.8799],[-105.0209,37.8859],[-105.0313,37.8919],[-105.0295,37.8964],[-105.03,37.9],[-105.0346,37.9055],[-105.0468,37.9115],[-105.0474,37.9967],[-105.0481,38.0855],[-105.0481,38.173],[-105.0483,38.202],[-105.0487,38.2582],[-104.9391,38.2587],[-104.9402,38.3448],[-104.9392,38.4178],[-104.939,38.43],[-104.9397,38.5003],[-104.9427,38.5003],[-104.943,38.5175],[-104.8295,38.5183],[-104.736,38.5183],[-104.7171,38.5186],[-104.6071,38.5187],[-104.4971,38.5192],[-104.3759,38.52],[-104.2836,38.5201],[-104.2794,38.5205],[-104.2759,38.5204],[-104.1629,38.5215],[-104.054,38.523],[-103.9411,38.523],[-103.8328,38.523],[-103.7228,38.5223],[-103.6116,38.5225],[-103.6118,38.5171],[-103.5089,38.5159],[-103.508,38.4366],[-103.5066,38.3409],[-103.5019,38.3408],[-103.5004,38.2646],[-103.3972,38.2647],[-103.2787,38.2649],[-103.1691,38.2647],[-103.0571,38.2647],[-102.741,38.2654],[-102.6154,38.2661],[-102.5075,38.2662],[-102.396,38.2662],[-102.2858,38.2665],[-102.1749,38.2668],[-102.0443,38.2676],[-102.0443,38.2627],[-102.0432,37.7384],[-102.043,37.6429],[-102.089,37.643],[-102.199,37.6429],[-102.3071,37.6435],[-102.4182,37.6432],[-102.5281,37.6432],[-102.6363,37.6435],[-102.7445,37.6428]]]},\"properties\":{\"name\":\"Bent\",\"state\":\"CO\"}}]}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a1be4b07f02db606ec9","contributors":{"authors":[{"text":"Luckey, Richard R.","contributorId":17980,"corporation":false,"usgs":true,"family":"Luckey","given":"Richard","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":169924,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

It is a semiarid area along the San Juan River near the communities of Montezuma Creek and Aneth. Within the Blanding Basin, geologic formations exposed are of Jurassic and Quaternary age. The rock strata are nearly horizontal, dipping gently northeastward. Wells derive small quantities of mater for domestic use from aquifers in the Morrison Formation and the Bluff Sandstone of Jurassic age, but aquifers in deeper formations contain saline mater or brine. Alluvium consisting of sand and gravel along the San Juan River is a potential source of additional moderately large quantities of water to shallow wells for industrial use and public supply.

Within the Yakutat region are some of the tallest mountains, some of the heaviest snowfalls, and the largest glacier in North America. Between the abrupt mountain front and the Gulf of Alaska lies a very gently sloping plain of outwash derived from repeated cycles of advance followed by melt and retreat of glaciers during the Quaternary Period. The latest melting probably took place 500 to 600 years ago. Yakutat is built upon the moderately steep moraine that is the product of melting of one of these glaciers. Near Yakutat, surficial deposits are as much as 700 feet thick and probably overlie siltstone, sandstone, and mudstone. The eight general categories of mapped surficial deposits include artificial fill, organic, eolian, beach, delta-estuarine, alluvial, and outwash deposits, and deposits of the outer Yakutat Bay moraine complex.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr75529","usgsCitation":"Yehle, L.A., 1975, Preliminary report on the reconnaissance engineering geology of the Yakutat area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards: U.S. Geological Survey Open-File Report 75-529, Report: iv, 136 p.; 2 Plates: 17.55 x 23.84 inches and 23.76 x 22.10 inches, https://doi.org/10.3133/ofr75529.","productDescription":"Report: iv, 136 p.; 2 Plates: 17.55 x 23.84 inches and 23.76 x 22.10 inches","costCenters":[],"links":[{"id":419431,"rank":4,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0529/figure-2.pdf","text":"Figure 2","linkFileType":{"id":1,"text":"pdf"}},{"id":419430,"rank":3,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0529/figure-4.pdf","text":"Figure 4","linkFileType":{"id":1,"text":"pdf"}},{"id":419427,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0529/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":150377,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0529/report-thumb.jpg"}],"scale":"63360","country":"United States","state":"Alaska","otherGeospatial":"Yakutat area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -140.46791499075454,\n              59.89062741426659\n            ],\n            [\n              -140.46791499075454,\n              59.494396417496176\n            ],\n            [\n              -139.5015327447604,\n              59.494396417496176\n            ],\n            [\n              -139.5015327447604,\n              59.89062741426659\n            ],\n            [\n              -140.46791499075454,\n              59.89062741426659\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aaee4b07f02db66c788","contributors":{"authors":[{"text":"Yehle, Lynn A. yehle@usgs.gov","contributorId":3794,"corporation":false,"usgs":true,"family":"Yehle","given":"Lynn","email":"yehle@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":173258,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
