Abstract:

Ryerson Station State Park Dam is a 515-foot-long concrete gravity structure. A 200-foot-long ogee section near the right abutment looking downstream is the combined primary and emergency spillway of the dam. The maximum height of the dam is about 30 feet for the spillway and 42 feet for the nonoverflow section measured from the downstream toe. The width of the dam varies from a minimum of 6 feet at the crest of the nonoverflow section to about 30 feet at the base of the dam. The outlet works for the dam consist of a 36-inch-diameter conduit through the dam left of the spillway. Flow through the outlet conduit is controlled by a manually operated sluice gate located at the upstream end. The outlet works constitute the emergency drawdown facility for the reservoir. The dam is located in Ryerson Station State Park approximately one mile upstream from the town of Ryerson Station in Richville Township, Greene County, Pennsylvania.
