West Valley, also known as West Valley Reservoir, is a critical water resource located in Modoc County, California. Owned by a public utility, this reservoir plays a vital role in providing water for irrigation and general water supply purposes. Completed in 1936, the dam stands at a height of 65 feet and has a storage capacity of 23,000 acre-feet, serving the local community in Likely, California.

Managed by the California Department of Water Resources (DWR) and regulated by the Safety of Dams program, West Valley Dam is situated on the West Valley Creek. With a surface area of 1050 acres and a drainage area of 136 square miles, the reservoir has a high hazard potential but is currently in satisfactory condition as of the last assessment in 2017. The dam underwent its last inspection in October 2020, with regular inspections conducted to ensure its safety and integrity.

Despite its age, West Valley Dam continues to be a crucial water storage and supply infrastructure in the region. With enforcement, permitting, and inspection protocols in place, the reservoir remains a reliable resource for the community, highlighting the importance of sustainable water management practices in the face of climate change challenges.
