Although tributaries of the Big Blue River have eroded valleys into this plain, much of the original surface is intact. Broad flats and numerous shallow undrained depressions characterize the plain. \r\n\r\nThe county is underlain by unconsolidated deposits of Quaternary age to depths ranging from about 80 to 450 feet. The upper part of this depositional sequence consists largely of wind-deposited clayey silt, and the lower part of stream-deposited sand and gravel. In part of the county, deposits of glacial till also are included. The Quaternary deposits mantle an eroded surface of marine-deposited strata of Cretaceous age. \r\n\r\nThe lower deposits of Quaternary age are saturated and constitute a highly productive aquifer throughout much of the county. The saturated zone ranges from about 20 to 350 feet in thickness. Replenishment to this aquifer, derived principally from precipitation, is believed to average about 1.4 inches per year. Because the quantity of ground water pumped per year exceeds the average annual quantity of recharge, some of the water used for irrigation is from storage. Consequently, water levels in wells .are declining. This trend is likely to continue. \r\n\r\nThe ground water is of the calcium bicarbonate type and is hard, but it is chemically suitable for irrigation use on most soils in the county.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wsp1839L","usgsCitation":"Keech, C.F., Dreeszen, V., and Petri, L.R., 1968, Geology and ground-water resources of Fillmore County, Nebraska, with a section on chemical quality of the water: U.S. Geological Survey Water Supply Paper 1839, Report: iv, 27 p.; 2 Plates: 45.81 x 36.50 inches and 37.00 x 16.49 inches, https://doi.org/10.3133/wsp1839L.","productDescription":"Report: iv, 27 p.; 2 Plates: 45.81 x 36.50 inches and 37.00 x 16.49 inches","costCenters":[],"links":[{"id":110026,"rank":5,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25053.htm","linkFileType":{"id":5,"text":"html"},"description":"25053"},{"id":27470,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1839l/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":27471,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/1839l/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":137581,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/1839l/report-thumb.jpg"},{"id":27469,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1839l/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Nebraska","county":"Fillmore County","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-97.3685,40.699],[-97.3678,40.4376],[-97.3686,40.3514],[-97.4827,40.3506],[-97.8206,40.351],[-97.8236,40.3505],[-97.8246,40.4367],[-97.8256,40.5243],[-97.826,40.6105],[-97.8245,40.6985],[-97.7111,40.6983],[-97.3685,40.699]]]},\"properties\":{\"name\":\"Fillmore\",\"state\":\"NE\"}}]}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adbe4b07f02db685b6d","contributors":{"authors":[{"text":"Keech, Charles Franklin","contributorId":44123,"corporation":false,"usgs":true,"family":"Keech","given":"Charles","email":"","middleInitial":"Franklin","affiliations":[],"preferred":false,"id":144529,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dreeszen, V.

Some changes were caused by enrichment of the environment, but others primarily by an intensive and selective fishery for certain species. Major changes related to the fishery were less frequent before the late 1930's than in recent years and involved few species. Lake sturgeon (Acipenser fulvescens) were overexploited knowingly during the late 1800's because they interfered with fishing for preferred species; sturgeon were greatly reduced in all lakes by the early 1900's. Heavy exploitation accompanied sharp declines of lake herring (Leucichthys artedi) in Lake Erie during the 1920's and lake whitefish (Coregonus clupeaformis) in Lake Huron during the 1930's. A rapid succession of fish species in Lakes Huron, Michigan, and Superior that started about 1940 has been caused by selective predation by the sea lamprey (Petromyzon marinus) on native predatory species, and the resultant shifting emphasis of the fishery and species interaction as various species declined. Lake trout (Salvelinus namaycush) and burbot (Lota lota), the deepwater predators, were depleted first; this favored their prey, the chubs (Leucichthys spp.). The seven species of chubs were influenced differently according to differences in size. Fishing emphasis and predation by sea lampreys were selective for the largest species of chubs as lake trout and burbot declined. A single slow-growing chub, the bloater, was favored and increased, but as the large chubs declined the bloater was exploited by a new trawl fishery. The growth rate and size of the bloater increased, making it more vulnerable to conventional gillnet fishery and lamprey predation. This situation in Lakes Michigan and Huron favored the small alewife (Alosa pseudoharengus) which had recently become established in the upper Great Lakes, and the alewife increased rapidly and dominated the fish stocks of the lakes. The successive collapses of various stocks after periods of stable production may give some indication of their sustainable yield. The sea lamprey is being brought under control in Lakes Superior, Michigan, and Huron; lake trout are being established; and chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch), kokanee salmon (O. nerka), and the splake, a hybrid of lake trout and brook trout (Salvelinus fontinalis), are being introduced to reestablish a new species balance. Fish stocks are in a state of extreme instability in these lakes. Careful control of stocking programs and fisheries, and coordination of management among the various states of the United States and the province of Canada (Ontario) which manage the fish stocks, will be required to restore and maintain a useful fishery balance.</p>","language":"English","publisher":"NRC Research Press","doi":"10.1139/f68-063","usgsCitation":"Smith, S.H., 1968, Species succession and fishery exploitation in the Great Lakes: Journal of the Fisheries Research Board of Canada, v. 25, no. 4, p. 667-693, https://doi.org/10.1139/f68-063.","productDescription":"27 p.","startPage":"667","endPage":"693","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133049,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a60e4b07f02db635061","contributors":{"authors":[{"text":"Smith, Stanford H.","contributorId":86711,"corporation":false,"usgs":true,"family":"Smith","given":"Stanford","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":308486,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The facility is unique in that the rate of recharge to a buried sand and gravel aquifer is augmented by perforating an overlying bed of clay using hydraulic connectors (gravel-filled bored holes) in conjunction with an open-pit excavation. The connectors were drilled by typical well-boring techniques and the open pit was excavated by common construction methods. The recharge technique made it possible to add about million gallons per day of water to underground storage with a total capital investment of about $200,000. The alternative originally proposed was a 50-mile long pipeline to Garrison Reservoir, at a 1959 estimated cost of $12,000,000. The recharge technique employed at Minot should have wide application in the ground-water industry in areas where natural recharge to permeable deposits is impeded by overlying beds of low permeability.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6584.1968.tb01650.x","usgsCitation":"Pettyjohn, W.A., 1968, Design and construction of a dual recharge system at Minot, North Dakota: Groundwater, v. 6, no. 4, p. 4-8, https://doi.org/10.1111/j.1745-6584.1968.tb01650.x.","productDescription":"5 p.","startPage":"4","endPage":"8","costCenters":[{"id":478,"text":"North Dakota Water Science Center","active":true,"usgs":true},{"id":34685,"text":"Dakota Water Science Center","active":true,"usgs":true}],"links":[{"id":352370,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"North Dakota","city":"Minot","volume":"6","issue":"4","noUsgsAuthors":false,"publicationDate":"2006-07-06","publicationStatus":"PW","scienceBaseUri":"5aff5db8e4b0da30c1bfdd92","contributors":{"authors":[{"text":"Pettyjohn, Wayne A.","contributorId":20724,"corporation":false,"usgs":true,"family":"Pettyjohn","given":"Wayne","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":730697,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The discovery of the source of NRM in these basalts is important because the correlations obtained recently by several workers between high oxidation and reversed polarity in basalts appear to support the possibility of self-reversal, even though some of the rocks studied give independent indications that the reversed magnetizations are due to field reversal.</p><p>In one type of grain analysed the probe data are consistent with a titanohematite phase and a pseudobrookite phase. This agrees with previous petrographic data. In the other type of grain the probe data are consistent with one phase of titanohematite but contradict petrographic data by showing that the other phase cannot be titanomagnetite. It is concluded that significant contributions to the NRM could possibly arise from the titanohematite (whose magnetic properties in basalts are little known) or the unindentified phase (unless subsequent work rules this phase out), but not in the pseudobrookite phase. However, the NRM may not lie in the analysed grains at all; and other workers are at present investigating this possibility.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0031-9201(68)90052-6","issn":"00319201","usgsCitation":"Smith, P., 1968, Paleomagnetism and the compositions of highly-oxidised iron-titanium oxides in basalts: Physics of the Earth and Planetary Interiors, v. 1, no. 2, p. 88-92, https://doi.org/10.1016/0031-9201(68)90052-6.","productDescription":"5 p.","startPage":"88","endPage":"92","numberOfPages":"5","costCenters":[],"links":[{"id":219339,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a741ee4b0c8380cd77458","contributors":{"authors":[{"text":"Smith, P.J.","contributorId":6579,"corporation":false,"usgs":true,"family":"Smith","given":"P.J.","email":"","affiliations":[],"preferred":false,"id":357544,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
