About Summit Lake Reservoir
The primary purpose of Summit Lake Reservoir is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Pa American Water Company (private). It impounds the Summit Lake Creek.
The dam stands 30 feet tall and stretches 380 feet across, creates a reservoir covering 55 acres, has a maximum storage capacity of 1,146 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1875, the structure is one of the older dams in the region, with over a century and a half of service.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 01/26/2021.
