The eastern part of the basin is composed of steptoes and foothills which are generally above an altitude of 2,600 feet; the central part is of moderate local relief and is mantled chiefly by thick loess deposits; and the western part is characterized by low relief and scabland topography and is underlain mostly by basalt. \r\n\r\nPrecipitation increases eastward across the study area. It ranges annually from 12 to 18 inches in the western part and from 14 to 23 inches in the central part, and it exceeds 40 inches in the eastern part. \r\n\r\nSurface runoff from the basin for the 4-year period of study (July 1961-June 1965) averaged 408,000 acre-feet per year, compared with 445,200 acre-feet per year for the 27-year period of record. The eastern part of the basin contributed about 55 percent of the total, whereas the central and western parts contributed 37 percent and 8 percent, respectively. Most sediment transport from the Palouse River basin and the highest sediment concentrations in streams occurred in the winter. Of the several storms during the study period, those of February 3-9, 1963, December 22-27, 1964, and January 27-February 4, 1965, accounted for 81 percent of the total 4-year suspended-sediment load; the storm of February 3-9, 1963, accounted for nearly one-half the total load. The discharge-weighted mean concentration of suspended sediment carried in the Palouse River past Hooper during the study period was 2,970 milligrams per liter. \r\n\r\nThe average annual sediment discharge of the Palouse River at its mouth was about 1,580,000 tons per year, and the estimated average annual sediment yield was 480 tons per square mile. The yield ranged from 5 tons per square mile from the western part of the basin to 2,100 tons per square mile from the central part. The high yield from the central part is attributed to a scarcity of vegetal cover, to the fine-grained loess soils, and to rapid runoff during winter storms. Sediment yield from the eastern part of the basin ranged from 460 to more than 1,000 tons per square mile.\r\n\r\nDuring high flow, silt particles make up the largest part of the suspended-sediment load, whereas during low flow, clay particles represent the greatest part. On the average, the suspended sediment transported by the Palouse River past Hooper contained 3 percent sand, 68 percent silt, and 29 percent clay. Unmeasured sediment discharge was estimated to have been 5 percent of the total sediment discharge. \r\n\r\nData collected during the 4-year period of study show that sediment loads were higher than those recorded by V. G. Kaiser during the longer period 1939-65. Whereas Kaiser's study showed an average annual soil loss of 9.6 million tons, the average annual loss during the recent study was 14.2 million tons. \r\n\r\nThe factor that has had the greatest effect on the increase of sediment yields is land use. Lands once covered and protected by natural vegetation have been extensively, cultivated, and much of the soil has become susceptible to erosion, particularly in areas mantled by loessal soils.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wsp1899C","usgsCitation":"Boucher, P.R., 1970, Sediment transport by streams in the Palouse River basin, Washington and Idaho, July 1961-June 1965: U.S. Geological Survey Water Supply Paper 1899, Report: iv, 37 p.; 1 Plate: 26.50 × 24.50 inches, https://doi.org/10.3133/wsp1899C.","productDescription":"Report: iv, 37 p.; 1 Plate: 26.50 × 24.50 inches","costCenters":[],"links":[{"id":110035,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25118.htm","linkFileType":{"id":5,"text":"html"},"description":"25118"},{"id":137923,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/1899c/report-thumb.jpg"},{"id":25713,"rank":2,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1899c/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":25714,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/1899c/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Idaho, Washington","otherGeospatial":"Palouse River basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -116.508,\n              47.483\n            ],\n            [\n              -118.322,\n              47.483\n            ],\n            [\n              -118.322,\n              46.517\n            ],\n            [\n              -116.508,\n              46.517\n            ],\n            [\n              -116.508,\n              47.483\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e9e4b07f02db5e94ca","contributors":{"authors":[{"text":"Boucher, P.

The area is fortunate in having abundant supplies of generally good quality water available for present and projected future needs. Lake Michigan and ground-water reservoirs have great potential for increased development. Lake Michigan assures the urbanized area in the eastern part of the two counties of a nearly inexhaustible water supply. In 1967 the cities of Racine and Kenosha pumped an average of 32.6 mgd (million gallons per day) from the lake. Water from Lake Michigan is of the calcium magnesium bicarbonate type, but it is less hard than water from other sources. Discharge from Racine and Kenosha Counties into Lake Michigan is low and has little effect on the lake. The Root and Pike Rivers and a number of smaller streams contribute a mean flow of about 125 cfs (cubic feet per second) to the lake. Ground water, approximately 5 cfs, enters the lake as discharge from springs or as seeps. The Des Plaines, Root, and Pike Rivers drain areas of relatively impermeable silty clay that promotes rapid surface runoff and provides little sustained base flow. Sewage sometimes accounts for most of the base flow of the Root River. In contrast, the Fox River, which drains the western half of the area, has steady and dependable flow derived from the sand and gravel and the Niagara aquifers. Sewage-plant effluent released to the Fox River in 1964 was about 5 percent of the total flow. A 5-mile reach of the Root River loses about 30,000 gpd (gallons per day) per mile to the local ground-water reservoir and is a possible source of ground-water contamination. Thirty-five of the 43 lakes in the area are the visible parts of the groundwater table, and their stages fluctuate with changes in ground-water levels. The rest of the lakes are perched above the ground-water table. Flooding is a recurring but generally minor problem along occupied reaches of flood plains of all the streams. However, in 1960 a flood on the Fox River, which had a recurrence interval of 60 years, caused considerable damage near the village of Silver Lake. At the same time, a flood on the Root River, which had a recurrence interval of 100 years, caused damage in Racine. The sandstone aquifer, a major artesian reservoir underlying all of Racine and Kenosha Counties, is used as a water supply for industries, institutions, and three communities. Pumpage for these uses was about 3.3 mgd in 1967. The greatest decline of water levels, attributed to both local and regional pumping, was 7 feet per year at Burlington. The specific capacities of wells developed in the Mount Simon Sandstone are about 5 gpm (gallons per minute) per foot of drawdown; in the Galesville and Franconia Sandstones, about 4 gpm per foot of drawdown; and in the St. Peter Sandstone, about 1 gpm per foot of drawdown. Yields of more than 1,000 gpm are obtained from wells tapping the Galesville and Franconia Sandstones and penetrating large crevices in the Trempealeau Formation near Burlington and Union Grove. About 2.5 mgd of ground water in the sandstone aquifer was diverted from the two-county area toward the Milwaukee and Chicago pumping centers in 1963--about 1.7 mgd moving from Racine County toward Milwaukee and 0.8 mgd moving from Kenosha County toward Chicago. Recent regional waterlevel declines in the sandstone aquifer have ranged from about 3 to 5 feet per year. This decline in water levels represents a ground-water depletion of about 0.5 mgd; however, the aquifer is not being dewatered, nor are water levels declining in the recharge area. The sandstone aquifer receives about 80 percent of its recharge from its outcrop area west of the two counties. In 1963 about 3.5 mgd moved eastward laterally from the recharge zone in western Walworth County, and about 1 mgd leaked downward through the overly</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wsp1878","collaboration":"Prepared in cooperation with University Extension-the University of Wisconsin Geological and Natural History Survey","usgsCitation":"Hutchinson, R.D., 1970, Water resources of Racine and Kenosha Counties, southeastern Wisconsin: U.S. Geological Survey Water Supply Paper 1878, Report: v, 63 p.; 4 Plates:35.50 x 17.94 inches or smaller, https://doi.org/10.3133/wsp1878.","productDescription":"Report: v, 63 p.; 4 Plates:35.50 x 17.94 inches or smaller","numberOfPages":"70","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"links":[{"id":27302,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1878/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":27303,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1878/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":27304,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1878/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":27305,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1878/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":27306,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/1878/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":138546,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/1878/report-thumb.jpg"}],"country":"United States","state":"Wisconsin","county":"Kenosha County, Racine County","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-87.801,42.671],[-87.8037,42.6642],[-87.8057,42.6574],[-87.8097,42.6466],[-87.8138,42.6344],[-87.8164,42.6267],[-87.8178,42.6217],[-87.818,42.6153],[-87.8187,42.6108],[-87.8176,42.6049],[-87.8171,42.5999],[-87.8166,42.5953],[-87.8154,42.5917],[-87.8124,42.5866],[-87.8126,42.5812],[-87.8128,42.573],[-87.8123,42.5662],[-87.8125,42.558],[-87.8134,42.5448],[-87.8131,42.5348],[-87.8115,42.523],[-87.8086,42.512],[-87.8063,42.5047],[-87.8046,42.4992],[-87.8029,42.4962],[-87.8854,42.4967],[-87.995,42.4972],[-88.0647,42.4975],[-88.1163,42.4975],[-88.1766,42.4981],[-88.1945,42.4981],[-88.1971,42.4981],[-88.3016,42.4979],[-88.3027,42.6134],[-88.3044,42.8444],[-88.1868,42.8451],[-88.0699,42.8447],[-87.9524,42.8448],[-87.8355,42.8447],[-87.8268,42.8446],[-87.8262,42.8423],[-87.822,42.8336],[-87.8135,42.8244],[-87.8043,42.8156],[-87.7946,42.8064],[-87.7884,42.8018],[-87.7798,42.7967],[-87.7687,42.792],[-87.762,42.7864],[-87.7589,42.7823],[-87.759,42.78],[-87.7647,42.7769],[-87.7737,42.768],[-87.7795,42.758],[-87.7797,42.7517],[-87.7817,42.7471],[-87.7789,42.7321],[-87.779,42.7285],[-87.7773,42.7239],[-87.7773,42.7212],[-87.7825,42.7126],[-87.7845,42.7072],[-87.7853,42.7017],[-87.7911,42.6941],[-87.7925,42.6895],[-87.7951,42.6828],[-87.8003,42.6728],[-87.801,42.671]]]},\"properties\":{\"name\":\"Kenosha\",\"state\":\"WI\"}}]}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f4e4b07f02db5f079b","contributors":{"authors":[{"text":"Hutchinson, R.

The district project includes 11 study areas ranging from 18 to 80 square miles in size and from 0 to 67 in percent of study area controlled by floodwaterretarding structures. The 11 study areas are within that part of Texas where the west-to-east average annual runoff ranges from about 2 to 7 inches. This report presents results of analyses, development of methodolgy, and results of application of methods for defining the downstream effects of systems of floodwaterretarding structures.</p>\n<p>Annual inflow to and outflow from the system of floodwater-retarding reservoirs in seven of the 11 study areas were found to be related by the equation: O=0.98/ 0.68, where O is annual outflow, in inches, and / is annual net inflow, in inches. Transmission loss of structure outflow to the downstream study-area stream-gaging station was determined and compared with the transmission loss of natural flood flow between tandem stream-gaging stations on Denton Creek, a tributary to Elm Fork Trinity River above Dallas.</p>\n<p>Trap efficiency of most floodwater-retarding structures was found by the U.S. Soil Conservation Service to be about 97 percent. Downstream increases in suspended-sediment concentration in the outflow were found to be large in a study area with mostly silt and clay sediments, but even a large increase in suspendedsediment concentration did not represent a significant quantitative pickup of sediment by the outflow water.</p>\n<p>Water consumption in floodwater-retarding reservoirs from the combined actions of evaporation, evapotranspiration, and seepage was found to be as much as twice the average annual consumption attributable to evaporation alone. Average annual consumption in reservoirs in the seven study areas analyzed ranged from 1.57 inches of equivalent runoff in the easternmost study area, where annual runoff averaged 6.96 inches, to 0.77 inch of equivalent runoff in the westernmost study area, where the average annual runoff was 2.35 inches. The effect of consumption on downstream flow is partially offset by rainfall on pool surface. Studies covering as much as 15 years of streamflow record at the stream-gaging&nbsp;stations that gage outflow from the Deep and Honey Creek study areas indicated no increase in base flow.</p>\n<p>Multiple-linear-regression techniques were used in developing methodology to determine reservoir consumption in seven study areas. The physical and climatic fnctors influencing consumption were grouped as variables in regard to their relative effect on the actions of evaporation, evapotranspiration, and seepage. The resulting generalized equation was then used in synthesizing the consumptive effects of a planned system of 162 floodwater-retarding reservoirs controlling 26 percent of a 1,660-square-mile drainage basin upstream from a major water-supply reservoir. The analyses were based on the assumption that all water consumed at the floodwater-retarding reservoirs would have reached the downstream watersupply reservoir. Water-sediment discharge relationships were derived for the runoff into the structures as well as for the runoff through and below the structures. A mathematical response model of the floodwater-retarding reservoir systems and the entire drainage basin was computer programed to yield monthly water and sediment inflow to the water-supply reservoir.</p>\n<p>Results of the response model showed that with full development, depletion of annual yield to the large reservoir would be as much as 10 percent in the early years; but after the permanent pools of the floodwater-retarding structures had mostly filled with sediment, depletion of annual yield would be generally less than 1 percent. The depletion of yield to Garza-Little Elm Reservoir during the 39-year synthesized period of study was estimated as 296,800 acre-feet out of 18,256,000 acre-feet total yield. During the same period, the floodwater-retarding structures were estimated to have kept 19,700 acre-feet of sediment from being deposited in the reservoir.</p>\n<p>\"Firm\"- or \"critical\"-yield studies were made of the large reservoir on the basis of two sets of conditions : with floodwater-retarding structures in the drainage basin, and without such structures. Results of the firm-yield studies indicated that with full development, annual firm yield would be initially reduced by 10 percent. After 30 or more years, when the permanent pools of the floodwaterretarding reservoirs would be mostly filled with sediment, the firm yield would be almost the same with or without the upstream development.</p>","language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","doi":"10.3133/wsp1984","usgsCitation":"Gilbert, C.R., and Sauer, S.P., 1970, Hydrologic effects of floodwater-retarding structures on Garza-Little Elm Reservoir, Texas: U.S. Geological Survey Water Supply Paper 1984, Report: vii, 95 p.; 3 Plates: 39.48 x 33.34 inches or smaller, https://doi.org/10.3133/wsp1984.","productDescription":"Report: vii, 95 p.; 3 Plates: 39.48 x 33.34 inches or smaller","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":414124,"rank":6,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25366.htm","linkFileType":{"id":5,"text":"html"}},{"id":94719,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1984/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":94718,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1984/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":138233,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/1984/report-thumb.jpg"},{"id":26745,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/1984/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":94717,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/1984/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Texas","otherGeospatial":"Garza-Little Elm Reservoir","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -96.775,\n              33.083\n            ],\n            [\n              -96.775,\n              33.625\n            ],\n            [\n              -97.617,\n              33.625\n            ],\n            [\n              -97.617,\n              33.083\n            ],\n            [\n              -96.775,\n              33.083\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a1be4b07f02db60703b","contributors":{"authors":[{"text":"Gilbert, Clarence R.","contributorId":30965,"corporation":false,"usgs":true,"family":"Gilbert","given":"Clarence","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":143950,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sauer, Stanley P.","contributorId":38966,"corporation":false,"usgs":true,"family":"Sauer","given":"Stanley","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":143951,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

L. Lugn, which is of late Miocene and early Pliocene age, contains diatomaceous and plant-bearing sediments at a locality on the north bluff of the Niobrara River, about 10 miles south of Kilgore, Cherry County, Nebr. The fossil flora has been studied by H. D. MacGinitie, who concluded that the deposit is of late Miocene age. Correlative strata near Valentine, Nebr., several miles east of this locality, are reported to contain a vertebrate fauna of late Miocene age. The Kilgore diatom assemblage consists of 45 taxa of nonmarine diatoms. Of these, four species are herein recorded as new, one species has been previously reported from the middle Pliocene of France, and the remaining 40 taxa are identified as still living in modern nonmarine environments. The diatom assemblage suggests deposition in a relatively shallow, small lake. The waters of this lake were probably hard, and perhaps at times somewhat alkaline or saline. It is difficult to separate the influences of ecology and geologic age on the composition of the diatom assemblage, but this problem should be resolved as other Tertiary assemblages are studied. The five presumably extinct species may prove to be useful for stratigraphic correlation when their geologic ranges are better known. The composition of the assemblage, the relative number of taxa, and the absence of several widespread modern genera and species of nonmarine diatoms should be of value in identifying other late Miocene assemblages and in distinguishing them from assemblages of different age.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Contributions to paleontology, 1970","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/pp683A","usgsCitation":"Andrews, G., 1970, Late Miocene nonmarine diatoms from the Kilgore area, Cherry County, Nebraska: U.S. Geological Survey Professional Paper 683, 40 p., https://doi.org/10.3133/pp683A.","productDescription":"40 p.","costCenters":[],"links":[{"id":119895,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/0683a/report-thumb.jpg"},{"id":67417,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/0683a/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Nebraska","county":"Cherry County","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-102.0829,42.9979],[-102.0007,42.9973],[-101.9652,42.9971],[-101.7528,42.9958],[-101.6775,42.9953],[-101.2277,42.9953],[-100.7509,42.9947],[-100.6721,42.9949],[-100.3938,42.996],[-100.1984,42.997],[-100.1985,42.8461],[-100.1984,42.782],[-100.184,42.7829],[-100.1837,42.4338],[-100.1675,42.4348],[-100.1667,42.0881],[-100.2675,42.0871],[-100.6156,42.0872],[-100.73,42.0885],[-100.8444,42.0896],[-100.9582,42.0897],[-100.9841,42.09],[-101.1016,42.0913],[-101.1926,42.0914],[-101.3094,42.0925],[-101.3323,42.0927],[-101.4097,42.0942],[-101.4251,42.0936],[-101.4492,42.0933],[-101.6861,42.0945],[-101.7733,42.0938],[-101.803,42.0934],[-101.8902,42.0962],[-101.9199,42.0958],[-102.0065,42.0958],[-102.0393,42.0962],[-102.0387,42.1826],[-102.0402,42.4448],[-102.0669,42.4448],[-102.0664,42.5302],[-102.0665,42.7867],[-102.0846,42.7864],[-102.0836,42.9606],[-102.0829,42.9979]]]},\"properties\":{\"name\":\"Cherry\",\"state\":\"NE\"}}]}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1be4b07f02db6a8bca","contributors":{"authors":[{"text":"Andrews, G.W.","contributorId":106549,"corporation":false,"usgs":true,"family":"Andrews","given":"G.W.","email":"","affiliations":[],"preferred":false,"id":221989,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Northern Alaska--the northeastern Brooks Range and the Arctic Coastal Plain--is underlain by a pre-Upper Devonian fold belt that may continue around the rim of the Canada Basin into the Franklinian geosyncline of the Canadian Arctic Islands. East-central Alaska, with a thinner, mainly carbonate rock section, seems to be a western extension of the Yukon shelf that separates the circum-Arctic geosynclinal trend from the Cordilleran

By design the instrument detected fluorescence specifically at the sodium D2 Fraunhofer line (5890 angstroms). The granules are used as a vehicle for airborne emplacement of poison to control fire ants in the eastern and southeastern United States. The granules are dropped with considerable precision but some targets are inevitably missed. It was hoped that the FLD could aid in detecting missed target areas. Test results showed that the granules are detectable by FLD but that the concentration must be too great to be practical with the present FLD. Possible methods for enhancement of response may include: (1) increasing dye concentration; (2) incorporating with the poisoned granules a second material to carry the dye alone; (3) use of a more strongly fluorescent substance (at 5890 A); (4) modifying the time interval after dyeing, or modifying the method of dyeing;(5) modifying the FLD for greater efficiency, increased field of view (FOV), or larger optics; or (6) experimenting with laser-stimulated fluorescence.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr70315","usgsCitation":"Stoertz, G.E., and Hemphill, W.R., 1970, Feasibility of surveying pesticide coverage with airborne fluorometer: U.S. Geological Survey Open-File Report 70-315, ii, 21 p., https://doi.org/10.3133/ofr70315.","productDescription":"ii, 21 p.","numberOfPages":"24","costCenters":[],"links":[{"id":150495,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1970/0315/report-thumb.jpg"},{"id":498402,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1970/0315/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49fee4b07f02db5f6f35","contributors":{"authors":[{"text":"Stoertz, George Eimert","contributorId":99572,"corporation":false,"usgs":true,"family":"Stoertz","given":"George","email":"","middleInitial":"Eimert","affiliations":[],"preferred":false,"id":172312,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hemphill, William R.","contributorId":21970,"corporation":false,"usgs":true,"family":"Hemphill","given":"William","email":"","middleInitial":"R.","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":172311,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The moraine is an area of hills and depressions. The local relief is low in the western part of the moraine but increases to more than 200 feet in the east. Altitude of the land surface ranges from 800 feet above mean sea level where the Red River flows north out of the area to 2,040 feet near the southeastern edge of the watershed (one of the highest points in Minnesota).</p>\n<p>The area of the watershed is about 2,600 square miles and includes most of Mahnomen and Norman Counties and parts of Becker, Clay, Clearwater, and Polk Counties. The population of the area is about 37,000 people of which about 70 percent live on farms. The economy is based principally on farming. The area of lake clay and silt is used mostly for raising sugar beets and wheat; and potatoes are grown largely on the sandy soils. In the western part of the morainal area small grain, dairy, and cattle farming is the most common. The eastern part of the morainal area is important for forest products and recreation. Industries in the area are small and are based on agricultural processing and service.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Washington, D.C.","doi":"10.3133/ha339","collaboration":"Prepared in cooperation with the Minnesota Department of Conservation, Division of Waters, Soils, and Minerals","usgsCitation":"Winter, T.C., Bidwell, L.E., and Maclay, R.W., 1970, Water resources of the Wild Rice River watershed, northwestern Minnesota: U.S. Geological Survey Hydrologic Atlas 339, Document: 1 p. 4 Plates: 41.66 x 40.27 inches or smaller, https://doi.org/10.3133/ha339.","productDescription":"Document: 1 p. 4 Plates: 41.66 x 40.27 inches or smaller","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":392,"text":"Minnesota Water Science Center","active":true,"usgs":true}],"links":[{"id":101437,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/ha/339/plate-1.pdf","size":"8948","linkFileType":{"id":1,"text":"pdf"}},{"id":101436,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/ha/339/report.pdf","size":"42","linkFileType":{"id":1,"text":"pdf"}},{"id":101438,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/ha/339/plate-2.pdf","size":"7443","linkFileType":{"id":1,"text":"pdf"}},{"id":101439,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/ha/339/plate-3.pdf","size":"7660","linkFileType":{"id":1,"text":"pdf"}},{"id":101440,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/ha/339/plate-4.pdf","size":"6766","linkFileType":{"id":1,"text":"pdf"}},{"id":189361,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/ha/339/report-thumb.jpg"}],"scale":"250000","country":"United States","state":"Minnesota","otherGeospatial":"Wild Rice River watershed","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -97,47 ], [ -97,47.5 ], [ -95.5,47.5 ], [ -95.5,47 ], [ -97,47 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f4e4b07f02db5f02df","contributors":{"authors":[{"text":"Winter, Thomas C.","contributorId":84736,"corporation":false,"usgs":true,"family":"Winter","given":"Thomas","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":277303,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bidwell, L.

This heavy rainfall, combined with the generally wet antecedent conditions of the spring season and some runoff from snowmelt, caused considerable flooding of the rivers in the area. Property damage in Massachusetts from the flood was reported by the New England Division, Corps of Engineers (1968) to be $28 million. Most of the damage occurred where construction, both industrial and domestic, had encroached upon the flood plains of the rivers.</span></p>\n<p><span>The Sudbury and Assabet Rivers join at Concord, Mass., to form the Concord River (see fig. 1).

These basic flood data, as compiled, will serve as a broad, sound basis to assist state and local planners in such measures as flood-plain zoning and flood containment and prevention.</span></p>\n<p>&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ha371","usgsCitation":"Petersen, R.G., Wood, G.K., and Gadoury, R.A., 1970, Flood of March 1968 on the Sudbury, Assabet, and Concord Rivers, Massachusetts: U.S. Geological Survey Hydrologic Atlas 371, 2 Plates: 47.00 x 40.50 inches, https://doi.org/10.3133/ha371.","productDescription":"2 Plates: 47.00 x 40.50 inches","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"links":[{"id":186307,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":393058,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_15750.htm"},{"id":91808,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/ha/371/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":91807,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/ha/371/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"12000","country":"United States","state":"Massachusetts","otherGeospatial":"Assabet River, Concord River, Sudbury River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -71.631,\n              42.25\n            ],\n            [\n              -71.25,\n              42.25\n            ],\n            [\n              -71.25,\n              42.648\n            ],\n            [\n              -71.631,\n              42.648\n            ],\n            [\n              -71.631,\n              42.25\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f2e4b07f02db5eed14","contributors":{"authors":[{"text":"Petersen, Richard G.","contributorId":44232,"corporation":false,"usgs":true,"family":"Petersen","given":"Richard","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":277636,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wood, G.

The study area consists of sixteen 7 1/2-minute quadrangles in Spotsylvania and adjoining counties, Virginia. East-west traverses were flown at a spacing of 1/2 mi and a flight elevation of 500 ft above ground. Geophysical data were compiled at a scale of 1:24,000, with a contour interval of 25 gammas for the magnetics and 25 counts per sec for the aeroradioactivity. The geophysical data were checked in the field, and a lithologic map was made. Correlation is excellent between geophysical data and lithologic units, and it is evident that good detailed aeromagnetic and aeroradioactivity maps can provide appreciable shortcuts in mapping an area such as the Piedmont, where lithologies are complex and outcrops sparse. Radioactivity highs are generally associated with magnetic lows, and more importantly, for purposes of geologic interpretation where the magnetic expression is flat and featureless, there is considerable radioactivity detail for geologic guidance. By using the two geophysical maps in conjunction, the geology between widely spaced outcrops can be worked out. In the study area, high radioactivity and low magnetic intensity characterize granitic rocks, many of which were not previously mapped. Mafic bodies are characterized by high magnetic values and low radioactivity. Much of the area is underlain by a sequence of metamorphosed sedimentary and volcanic rocks having alternating quartz-muscovite and magnetiferous chlorite-actinolite assemblages. © 1970, The Geological Society of America, Inc.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1970)81[3575:COAAAW]2.0.CO;2","issn":"00167606","usgsCitation":"Neuschel, S., 1970,  Correlation of aeromagnetics and aeroradioactivity with lithology in the Spotsylvania area, Virginia: Geological Society of America Bulletin, v. 81, no. 12, p. 3575-3582, https://doi.org/10.1130/0016-7606(1970)81[3575:COAAAW]2.0.CO;2.","productDescription":"8 p.

The Marquette Range Supergroup consists of the Chocolay, Menominee, Baraga, and Paint River Groups, as defined in previous literature. We feel that this new name to apply to Northern Peninsula rock units is appropriate, as continued investigations have failed to show unequivocal correlation between middle Precambrian rocks of Michigan and the Huronian Supergroup of Ontario. Although the equivalence of the Animikie Group in Ontario and Minnesota with parts of the Michigan rocks is likely, the Stratigraphic complexity of the Michigan sequence requires supergroup rank. The inherent confusion of an Animikie Group in Ontario and Minnesota, and an Animikie Supergroup in Michigan, makes a local name such as Marquette Range Supergroup preferable to Animikie for the middle Precambrian rocks of Michigan. © 1970, The Geological Society of America, Inc.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1970)81[2843:AROSNF]2.0.CO;2","issn":"00167606","usgsCitation":"Cannon, W., and Gair, J.E., 1970, A revision of stratigraphic nomenclature for middle precambrian rocks in Northern Michigan: Geological Society of America Bulletin, v. 81, no. 9, p. 2843-2846, https://doi.org/10.1130/0016-7606(1970)81[2843:AROSNF]2.0.CO;2.","productDescription":"4 p.
