About Dalton Lake Dam

The primary purpose of Dalton Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Baumeyer Enterprises Inc (private). It impounds the Tr-coldwater Ck near Womack.

The dam stands 33 feet tall, creates a reservoir covering 11 acres, has a maximum storage capacity of 194 acre-feet, and collects water from a drainage area of 530 square miles. Completed in 1974, 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. The most recent inspection on record was 08/09/1978. That was 47 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 33 feet, this dam is taller than 78% of dams nationwide.
