National Dam Inspection Program. Hutchinson Reservoir Dam Number 1 (NDI-PA-214), Ohio River Basin, Redstone Creek, Fayette County, Pennsylvania. Phase I Inspection Report.
Abstract
Hutchinson Reservoir Dam Number 1 is an earth embankment (with an upstream concrete face) approximately 308 feet in length and with a maximum height of 33 feet. The embankment reportedly is provided with a 2-foot thick clay puddle core wall extending 14 feet below the original ground surface. The facility is served by a rectangular concrete overflow spillway with a multiple vertical drop concrete discharge channel along the right abutment. A 20-inch diameter cast-iron pipe passing through the embankment serves as a supply line. Reservoir drawdown control is provided by a 14-inch diameter cast-iron blowoff conduit which parallels the 20-inch supply line. The blowoff conduit is valved on the upstream side within a concrete intake tower (referred to as a vault by the owner's personnel). At the upstream end of the reservoir is a sedimentation basin and miscellaneous appurtenances which can direct flow (via flash boards) into Reservoir Number 1 and/or into an earth and masonry raceway which can carry part of the inflow around the reservoir.
