The magnitude of a flood of any selected frequency up to 50 years for any site on any stream in the Snake River basin can be determined by methods outlined in this report, with some limitations. The methods are not applicable for regulated streams, for drainage basins smaller than 10 or larger than 5,000 square miles, for streams fed by large springs, or for streams that have flow characteristics

Electric-analog design criteria are established from the differential equations of ground-water flow for analyzing pumping-test data. A convenient analog design was obtained by transforming the cylindrical equation of flow to a rectilinear form. The design criteria were applied in the construction of an electric analog, which was used for studying pumping-test data collected near Grand Island, Neb

A geologic and hydrologic reconnaissance was made on the public domain of western Utah to appraise the water resources of the area and to provide a basis for locating and developing sources of stock water. The study area includes the Bonneville, Pahvant, and Virgin Grazing Districts, in parts of Tooele, Utah, Juab, Millard, Beaver, Iron, and Washington Counties, Utah.Western Utah is in the Great B

The Halma-Lake Bronson area covers about 80 square miles in the northwestern corner of Minnesota. It is a relatively featureless poorly drained glacial drift plain which slopes gently to the west about 10 feet per mile. The plain is interrupted by sand dunes and by beach deposits of Glacial Lake Agassiz. In the northeastern part of the area, the glacial drift rests on Preeambrian crystalline basem

Lyon County is in southwestern Minnesota, mostly within the drainage basin of the Minnesota River. The basement rocks in the area consist largely of Precambrian granite and quartzite. These are overlain locally by flat-lying Upper Cretaceous strata composed of thick sections of soft dark-bluish-gray shale and some thin beds of loosely consolidated sandstone. The Cretaceous strata are more than 500

In the Raft River basin in south-central Idaho, ground-water withdrawals for irrigation have more than doubled since 1955, when data were compiled for a comprehensive report on the area. The present report summerizes data on the ground-water use and changes in the water regimen during the intervening 5 years. Water levels have declined 10 to 20 feet in the areas of heaviest pumping and 3 to 5

Ground water in the United States has emerged from a quantitatively minor (though incalculably valuable) water source, whose chief role was in the settlement of primitive areas, to a major source now accounting for one-fifth to one-sixth of the Nation's total withdrawal requirements for water. With the growth in ground-water withdrawals is an accompanying growth in the realization that large-scale

Edwards County occupies 2,075 square miles of the southern part of the Edwards Plateau in southwest Texas. In 1950 it had a population of 2,908. Its thin limestone soil supports the characteristic flora of a semiarid region. The county is underlain by nearly flat-lying beds of limestone and a few beds of shale and marl. The Glen Rose limestone of Cretaceous age, the oldest formation tapped by wate

The southern part of the Camp Ripley Military Reservation, in central Minnesota, includes an area of about 20 square miles. This investigation was conducted to assist the U.S. National Guard Bureau in locating adequate water supplies for expansion and standby needs. Bedrock in the area consists of Precambrian phyllite which is equivalent to the Virginia slate. The area is covered largely by Pleist
