About Swan Lake Dam
The primary purpose of Swan Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by City of Hilltop Lakes (local government). It impounds the Running Creek near Normangee.
The dam stands 36 feet tall and stretches 950 feet across, creates a reservoir covering 20 acres, has a maximum storage capacity of 175 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1971, the structure is well into its service life at over 50 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 11/05/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.
At 36 feet, this dam is taller than 82% of dams nationwide.
