Ground-water levels in Wyoming, 1978 through September 1987

Groundwater levels are measured periodically in a network of 95 observation wells in Wyoming, mostly in areas where groundwater is used in large quantities for irrigation or municipal purposes. The program is conducted by the U.S. Geological Survey in cooperation with the Wyoming State Engineer and the Wyoming Economic Development and Stabilization Board. This report contains hydrographs for 95 observation wells showing water level fluctuations from 1978 through September 1987. Also included in the report are maps showing locations of observation wells and tables listing well depths, use of water, geologic source, records available, and highest and lowest water levels for the period of record.
