Cummings Dam

Cummings Dam is a concrete gravity structure approximately 455 feet long with a maximum height of 29 feet located across a tributary to Crooked Creek approximately 4 miles north of Indiana in Rayne Township, Indiana County. The dam was initially constructed in 1908 by the Buffalo, Rochester, and Pittsburgh Railway Company, but is now owned by Indiana County and is used for recreation as the centerpiece of Blue Spruce County Park. In 2007, Gibson-Thomas designed and oversaw a construction project to make concrete repairs to the dam crest and spillway sidewalls and to replace the 24″ low level sluice gate in the dam’s outlet works. The project was paid for through a combination of a Growing Greener grant and local funding.
