About Teal Lake Dam

The primary purpose of Teal Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by A P Green Refractory Co (private). It impounds the Tr-south Fork Salt River near Mexico.

The dam stands 20 feet tall, creates a reservoir covering 78 acres, has a maximum storage capacity of 835 acre-feet, and collects water from a drainage area of 3,387 square miles. Completed in 1969, 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 07/10/1980. That was 45 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
