Irrigation along the North Platte River in Wyoming began as early as 1875. Streams are the principal source of irrigation water with groundwater used to supplement surface-water irrigation supplies. There was concern that groundwater pumpage may have caused about 16 ft of water-level decline in an observation well over a 2-year period. Leakage or lack of leakage from surface-water diversions for

Certain physical characteristics of soils, including permeability, available water capacity, thickness, and topographic position, have a measurable effect on the hydrology of an area. These characteristics control the rate at which precipitation infiltrates or is transmitted through the soil, and thus they have an important role in determining the rates of actual evapotranspiration (consumptive wa

Several types of geologic and hydrologic data were collected and compiled as part of the Central Midwest Regional Aquifer-System Analysis. The study described the hydrology of Cambrian-age through Cretaceous-age rocks in all of Kansas and Nebraska and parts of eight other states. Information from both water wells and petroleum wells was obtained from numerous State, Federal, and private sources. T

This map describes the southeastern part of the Sweetwater River basin; the major aquifer consists of the upper part of the White River formations, all of Tertiary age, and to a small extent, the alluvium of the Quaternary age along the Sweetwater River. The saturated thickness of the aquifer in most of the area, but not including the alluvium ranges from 500 to 3000 ft. The maximum saturated thic

The geologic map of the Cheyenne Urban Area shows the following elements: (1) artificial fill at miscellaneous sites; (2) artificial fill in areas of large residential developments constructed since 1945; (3) artificial fill in areas of extensive construction activity; (4) undifferentiated alluvium (holocene); (5) terrace alluvium (holocene); (6) alluvial fan deposits (holocene); (7) slope deposit

Hydrologic information and analysis aid in decisions to lease federally owned coal and to prepare necessary Environmental Assessments and Impact Study reports. This need has become even more critical with the enactment of Public Law 95-87, the "Surface Mining Control and Reclamation Act of 1977." This act requires an appropriate regulatory agency to issue permits, based on the review of permit-app

Machine-readable files were developed for the High Plains Regional Aquifer-System Analysis project are stored on two magnetic tapes available from the U.S. Geological Survey. The first tape contains computer programs that were used to prepare, store, retrieve, organize, and preserve the areal interpretive data collected by the project staff. The second tape contains 134 data files that can be divi

Groundwater resources in the Hanna and Carbon Basins of Wyoming were assessed in a study from 1974 through 1980 because of the development of coal mining in the area. Data collected from 105 wells during that study, including well-completion records, lithologic logs, and water levels, are presented. The data are from stock wells, coal-test holes completed as observation wells by the U.S. Geologica
