Hart Lake Dam

About Hart Lake Dam

The primary purpose of Hart Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Hart Lake Conservancy District (local government). It impounds the Dry Fork Of Sycamore Creek.

The dam stands 34 feet tall and stretches 450 feet across, creates a reservoir covering 21 acres, has a maximum storage capacity of 404 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1950, the structure is well-established, with more than 75 years 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 10/24/2012. That was 13 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 34 feet, this dam is taller than 80% of dams nationwide.
