Hemlock Lake was originally called Straight Run Dam when it was completed by the Pennsylvania Fish Commission in 1970. The dam is 650 feet long and is 40 feet high at its highest point. The dam impounds a 60 acre lake. Its deepest point is approximately 33 feet.

Indiana County Parks leases the site from the Pennsylvania Fish & Boat Commission as a public recreation area.


The 205 acre park features a 60 acre lake with two boat launches and areas for picnicking, hunting, hiking and fishing (including ice fishing). Two pavilions at the park are available on a first-come first-served basis.

The lake has been stocked with bluegill, bass, catfish, muskellunge, walleye and northern pike. Fishermen may moor their boats at the park following regulations established by the Fish & Boat Commission. Learn more about the species of fish in Hemlock Lake (a.k.a. - Straight Run Lake) by reading the spring 2008 biologist's report. Only electric motors and hand propelled boats are permitted.

Other nearby recreation areas include PA State Gamelands #174, Cloe Dam (Jefferson County) and Little Mahoning Creek.

Please be advised that the access roads to Hemlock Lake do not receive winter maintenance.
