Mountain Pond Dam

About Mountain Pond Dam

The primary purpose of Mountain Pond Dam is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Firstfruits (private). It impounds the Snake R. - Offstream.

The dam stands 42 feet tall, creates a reservoir covering 2 acres, has a maximum storage capacity of 26 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1992, the structure is 34 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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 10/17/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.

At 42 feet, this dam is taller than 89% of dams nationwide.
