Bristol Swamp, located in Gaines, Pennsylvania, is a state-owned Earth-type dam built in 1976 by the USDA NRCS for the primary purpose of creating a Fish and Wildlife Pond. The dam has a height of 15 feet and a length of 530 feet, with a storage capacity of 90 acre-feet. It sits on Johnson Brook, within the Buffalo District, and is regulated by the Natural Resources Conservation Service.

With a low hazard potential and a moderate risk assessment rating, Bristol Swamp is considered a valuable asset for local wildlife and water resource management. The dam does not have controlled spillways or outlet gates, and its condition assessment is currently marked as "Not Available." Despite this, the dam's purpose for enhancing fish and wildlife habitats and its relatively low risk profile make it an important feature in the region's water resource and climate conservation efforts.

While details on inspections, emergency action plans, and risk management measures are not readily available, Bristol Swamp's contribution to the local ecosystem and water conservation efforts cannot be understated. As a state-owned structure with a focus on supporting fish and wildlife, this dam plays a crucial role in maintaining ecological balance and preserving water resources in Potter County, Pennsylvania.
