Lake Kah-tan-da No.3

About Lake Kah-tan-da No.3

The primary purpose of Lake Kah-tan-da No.3 is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Lake Kah-tan-da Est,inc (private). It impounds the Tr-nations Creek near Silver Lake.

The dam stands 34 feet tall, creates a reservoir covering 42 acres, has a maximum storage capacity of 764 acre-feet, and collects water from a drainage area of 1,207 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 09/27/1979. That was 46 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.
