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...

The prairie potholes in the North-Central States and in Canada are of glacial origin. Because many of them contain ponds or marshes, they are important in the production of livestock and waterfowl. The objective of the present investigation is to determine the amount of water that accumulates in and is used in the potholes in their natural environment. Two study areas were selected in...

This atlas is comprise of three maps of the conterminous United States which show separately the prevalent dissolved-solids concentrations, prevalent chemical type, and average sediment concentration of rivers. The river-composition data shown on plates 1-3 provide a starting point for evaluating our surface-water resources on a nationwide scale, indicate regions where acceptable...

The scientific and economic results of work by the United States Geological Survey during the fiscal year 1961, the 12 months ending June 30, 1961, are summarized in 4 volumes. This volume includes 143 short papers on subjects in the fields of geology, hydrology, and related sciences, prepared by members of the Geologic, Water Resources, and Conservation Divisions of the Survey. Some are

The estimated overage withdrawal use of water in the United States during 1960 was almost 270,000 mgd (million gallons per day), exclusive of water used to develop water power. This estimated use amounts to about 1,500 gpd (galIons per day) per capita. An additional 2,000,000 mgd were used to develop waterpower. Withdrawal use of water requires that the water be removed from the ground...

The magnitude of a flood of a selected frequency for any point in the two states may be determined by methods outlined in this report, with two limitations. These methods are not applicable for regulated streams or for small-drainage areas (in general, less than 100 square miles). The determination of the magnitude of a flood of a selected frequency in the two-state area is accomplished...
