Coyote Creek, also known as Hidden Valley Lake, is a privately owned dam located in Lake County, California. Built in 1968, this earth-type dam stands at a height of 92 feet and serves primarily for water supply purposes. With a storage capacity of 3375 acre-feet and a drainage area of 5.5 square miles, Coyote Creek plays a crucial role in managing water resources in the region.

The dam has a high hazard potential but is currently assessed to be in satisfactory condition, last inspected in September 2017. It is regulated by the California Department of Water Resources (DWR) and falls under the Safety of Dams program. The dam's emergency action plan (EAP) status is not specified, but its last revision was in November 2020. Despite its age, Coyote Creek continues to provide essential water supply and recreational opportunities while being subject to regular inspection and enforcement measures to ensure public safety.

Coyote Creek's location in the Hidden Valley area, managed by private owners, highlights the intersection of water resource management and climate resilience in California. With its significant storage capacity and strategic importance for water supply, the dam serves as a critical infrastructure for the region. Its continued operation, maintenance, and adherence to regulatory guidelines underscore the ongoing efforts to safeguard water resources and mitigate potential risks associated with dam operations in the face of changing climatic conditions.
