Quemahoning Reservoir

The Quemahoning Dam, located on Quemahoning Creek on the border of Quemahoning Township, Pennsylvania and Conemaugh Township, Pennsylvania, just south of Hollsopple, was constructed by the Manufacturers Water Company to supply water for the Cambria Steel Company's works in Johnstown, PA. Construction was begun in 1910 and completed in 1913. The reservoir created by this dam is about five miles long and two miles wide at its widest place, and drains into the Stoneycreek River and thence into the Kiski-Conemaugh system. It is the one of the largest artificial bodies of water in Pennsylvania, and is known as a stopover for migratory waterfowl, including geese, swans, and herons. It was sold by Bethlehem Steel Corporation (successor to Cambria Steel) to the Cambria Somerset Authority, which now operates it both for recreation and industrial water supply. Additionally, Somerset Borough has commenced construction of a pipeline from the reservoir to the borough to provide potable water. Fishing, boating, camping and occasional whitewater rafting are among the recreational activities available.

The reservoir is said to cover the American Indian village of Kickenapauling's Town, which was referred to in records of Christopher Gist, as well as in the 10 June 1779 deed of Joseph Johns, after whom Johnstown was named.
