Water resources of the Bighorn basin, northwestern Wyoming

Hydrologic Atlas 512
By: , and 



This 2-sheet map report includes the part of the Bighorn Basin and adjacent mountains in northwestern Wyoming. Water-bearing properties of the geologic units are summarized. The hydrogeologic map illustrates the distribution of wells in the different units and gives basic data on the yields of wells, depth of wells, depth to water, and dissolved solids and conductance of the water. Aquifers capable of yielding more than 1,000 gpm (gallons per minute) underlie the area everywhere, except in the mountains on the periphery of the basin. In 1970, approximately 29,500 of the 40,475 people living in the Bighorn Basin were served by municipal water supplies. The municipal supply for about 6,300 of these people was from ground water. The natural flows of streams in the Bighorn Basin differ greatly due to a wide range in the meteorologic, topographic, and geologic conditions of the basin. The station locations and the average discharge per square mile are shown on the map and give an indication of the geographic variation of basin yields. The maximum instantaneous discharge that has occurred at each station during its period of record is shown. Most of the runoff in the basin is from snowmelt in the mountains. (Woodard-USGS)
