History
During 1986-1989, the powerplant was shutdown when the reservoir was being drained to install a diaphragm cutoff wall for the length of the dam. In June 1989, the unit began generating again at new low-head capabilities. This was in part due to the addition of additional rip-rap being placed on the upstream face of the dam.
Seedskadee Project is one of the initial group of participating projects authorized with the Colorado River Storage Project on April 11, 1956 (70 Stat. 105).
The Seedskadee Project, a participating project of the Colorado River Storage Project, is in the Upper Green River Basin in southwestern Wyoming. It provides storage and regulation of the flows of the Green River for power generation, municipal and industrial use, fish and wildlife, and recreation.
Plan
Fontenelle Powerplant provides maximum generation of power from regulated base load river flows depending upon water availability. Flows/generation vary from 350 cubic feet per second/1 megawatt at low seasonal head to 1,550 cubic feet per second/11 megawatt at peak runoff periods. Fontenelle Powerplant is located adjacent to the toe of the dam, with a 10-foot power penstock branching from one of three river outlet works discharge conduits. The turbine has a water discharge capacity of 1,585 cubic feet per second.

Normal operations The powerplant was shut down 33 percent of the 10-year review period to construct and install the diaphragm cutoff wall.
