Lynch Canyon

About Lynch Canyon

The primary purpose of Lynch Canyon is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Solano Land Trust (private). It impounds the N. Fork Lynch Creek.

The dam stands 21 feet tall and stretches 430 feet across, creates a reservoir covering 20 acres, and has a maximum storage capacity of 80 acre-feet.

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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 03/05/2025.
