Report on surface geology and groundwater investigations of Mortons and Green Valley Well Fields. Final technical report, November 1980-May 1982. [Proposed WyCoalGas Project, Converse County, Wyoming; site evaluation]
The general region of investigation of this report is in the southern part of the Powder River Basin near the Town of Douglas, Wyoming. Two specific areas within this region were investigated to determine the groundwater potential with drilling and testing programs during the years 1973 to 1975. One area of investigation is located approximately 12 miles west of Douglas in T32 and 33N, R73 and 74W, and is known as the Green Valley Well Field. This area is situated in the foothills of the north end of the Laramie Range and encompasses approximately 25 square miles. In this area the Madison Formation limestone and the Flathead Formation sandstone are the aquifers of interest for groundwater production. The second area is located approximately 13 miles north of Douglas in T34 and 35N, R70 and 71W, and is known as the Mortons Well Field. This area encompasses about 30 square miles. In this area, the Lance Formation and Fox Hills Formation sandstones are the aquifers of interest. Contained within the body of this report are two geologic studies prepared by consulting geologists, Dr. Peter Huntoon and Henry Richter. These studies define the pertinent structural and groundwater geologic features in and in the vicinities of the Mortons and Green Valley Well Fields. A relatively complex structural geology was encountered in the Green Valley area. The study of the Mortons area suggests that the geology of this area is relatively uniform. Inventories of the water users in the vicinities of the two study areas are included at the back of this report in Appendix B. These inventories are comprised of water appropriations as recognized by the Wyoming State Engineer's Office. Both groundwater and surface water appropriations are inventoried within the Green Valley study area. Only groundwater appropriations are inventoried within the Mortons study area.
