 70. PROJECT:Middle Fork Dam
SPONSOR:State of Wyoming
LOCATION:Johnson County
PROGRAM:New Development
Purpose Chapter Session Account Appropriation Due Date

The proposed project would be located on the Middle Fork of the Powder River. The Middle Fork Reservoir would have a total capacity of 59,600 acre-feet, of which 47,700 acre-feet would be active storage for water supply and the remaining 11,900 acre-feet would be for the purposes of fisheries and recreation (minimum pool). The project would yield 32,200 acre-feet per year for industrial, agricultural and instream flow purposes. The project would cost approximately $55,000,000. In 1990, WWDC completed negotiations to obtain an interest in the reservoir permits from the Powder River Reservoir Corporation (PRRC). The transfer required a separate contract between EXXON U.S.A. and WWDC. EXXON has invested about 1.5 million dollars in the project and has a contract with the PRRC which had to be addressed before the state can proceed toward construction of the project. The Commission contracted with the USGS for a study of water quality parameters in the Powder River drainage. This report was completed in 1992.

The WWDC recommends that the project be retained at Level II-Hold status.
