Phoenix Lake, located in Marin County, California, is a vital water resource managed by a public utility. The dam, completed in 1907, stands at 90 feet high and has a storage capacity of 612 acre-feet. The primary purpose of the dam is water supply, serving the surrounding area through Ross Creek.

With a high hazard potential, Phoenix Lake is under the regulatory oversight of the California Department of Water Resources, Safety of Dams division. Regular inspections ensure the dam's structural integrity, with the most recent assessment in September 2017 deeming its condition satisfactory. The dam's emergency action plan is up-to-date, reflecting the commitment to maintaining safety and preparedness in the face of potential risks.

Enthusiasts of water resources and climate will find Phoenix Lake to be a fascinating example of a century-old earth dam supporting crucial water supply infrastructure in California. Its history, design, and ongoing management showcase the importance of effective regulation and maintenance to ensure the continued resilience of our water resources in the face of changing climate conditions.
