Mcnulty Lake Dam

About Mcnulty Lake Dam

The primary purpose of Mcnulty Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Terry Mcnulty (private). It impounds the Grouro Creek near Vida.

The dam stands 34 feet tall, creates a reservoir covering 27 acres, has a maximum storage capacity of 491 acre-feet, and collects water from a drainage area of 1,637 square miles. Completed in 1989, the structure is 37 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 01/10/1993. That was 33 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.
