About Lake Bryson Dam

The primary purpose of Lake Bryson Dam 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 City of Bryson (local government). It impounds the East Rock Creek.

The dam stands 34 feet tall and stretches 995 feet across, has a maximum storage capacity of 1,750 acre-feet, and collects water from a drainage area of 4 square miles. Completed in 1980, the structure is 46 years old.

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. An emergency action plan is in place for this dam. The most recent inspection on record was 04/02/2019. That was 7 years ago, which is on the longer end for a high-hazard structure.

At 34 feet, this dam is taller than 78% of dams nationwide.
