This report presents a procedure for estimating the magnitude and frequency of floods, within the range of the base data, for any site, gaged or ungaged. From the relation of annual floods to the mean annual flood, a composite frequency curve was derived for recurrence intervals of 1.1 to 50 years. For regions of similar hydrologic characteristics, curves were developed by multiple...

In making reconnaissances for water supplies on the public domain as part of the Soil and Moisture Conservation Program of the Department of the Interior, the Geological Survey obtains information on the availability of water that is useful for other purposes or in other areas. This report contains the information thus collected during the calendar year 1960 in 46 areas scattered...

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...

A water supply of 50 gpm (gallons per minute) is estimated to be sufficient to supply the present and future water demand at the monument. The Coconino sandstone of Permian age seems to be capable of yielding this quantity to a well between 1,500 and 2,700 feet deep in the vicinity of Fruita. Recharge to this aquifer probably is principally from the Fremont River. Water derived from the...

The development of water supplies from wells was placed on a rational basis with Darcy's development of the law governing the movement of fluids through sands and with Dupuit's application of that law to the problem of radial flow toward a pumped well. As field experience increased, confidence in the applicability of quantitative methods was gained and interest in developing solutions...

This inventory of published and unpublished sediment-load data contains a list of the sediment-transport measurements in the United States and Puerto Rico during October 1950 to September 1960, made by the agencies associated with the Subcommittee on Sedimentation. Some of the agencies have miscellaneous sediment data, such as single observations at scattered stations or observations on...

The purpose of this investigation was to obtain data on and study the factors affecting the salinity of the Delaware River from Philadelphia, Pa., to the Appoquinimink River, Del. The general chemical quality of water in the estuary is described, including changes in salinity in the river cross section and profile, diurnal and seasonal changes, and the effects of rainfall, sea level, and...

The surface-water records for the 1962 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of Indiana are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed by the Water Resources Division of the U.S. Geological Survey, under...
