The dam, located about 10 miles south of Johnstown, has a storage capacity of 12.4 billion gallons, and is capable of supplying 62 million gallons per day to customers. The Quemahoning site also includes about 3,500 acres along with the former Bethco Pines, a recreational area with facilities for boating, fishing, skeet shooting and other activities. Constructed in 1912, the lake has been officially closed to public angling and, as such, has never been studied by the Commission. In 1999, Area Fisheries Management 8 personnel conducted a lake inventory to quantify and qualify the lake as a fishery and to develop a fisheries management plan for implementation when the lake is open to public use.
