Project Summary: The Brazos River Authority owns and operates Morris Sheppard Dam, which forms Possum Kingdom Reservoir, which is a water supply reservoir, and is located in Palo Pinto County in Texas. Morris Sheppard Dam was constructed in 1941 and consists of an Ambursen flat-slab and buttress dam structure with a service spillway, earthen embankment section, emergency spillway, intake structure in addition to a 78 inch and 42 inch controlled outlet conduit. The service spillway section consists of nine bear-trap (roof weir) gates that pass floodwater downstream. Under normal conditions, the spillway gates are hydraulically operated by reservoir head. Reservoir water is allowed to flow into the gate chamber beneath the gate, making it buoyant, then the gate leaves are unlatched and lowered to release the water. To assist with gate operations during low reservoir conditions (i.e., elevation 995 and below), a spillway pump and piping system was utilized to supply pressurized water into the underside of the gates to assist in lowering and raising the gates. Due to modifications to the spillway piping in the dam (as part of a previous project), the spillway pump and piping system were disconnected. This project consisted of the supply and installation of new pipeline, valves, and conduit, providing temporary electrical services and performing final testing.
