Home Ranch Dam, located in Marin County, California, was completed in 1954 and is owned by the National Park Service. The dam stands at a height of 27 feet and has a storage capacity of 32 acre-feet, primarily used for fire protection, stock, and small fish pond purposes. Despite its relatively small size, the dam is considered to have significant hazard potential, although the condition assessment is currently not available.

The dam, constructed as an earth dam, serves as a crucial resource for the local community in San Francisco, providing essential water storage for firefighting efforts and agricultural needs. The National Park Service oversees the operations and regulatory aspects of the dam, with the Bureau of Reclamation conducting inspections. While the last inspection was in 2013, the Emergency Action Plan was last revised in 2017, ensuring preparedness for any potential risks or emergencies.

With its location in a high-risk seismic area and the potential for significant hazard, the Home Ranch Dam serves as a reminder of the importance of proper maintenance and monitoring of water infrastructure. As climate change continues to impact water resources, it is crucial for agencies like the National Park Service to prioritize the safety and resilience of dams like Home Ranch to ensure the sustainable management of water in the face of evolving environmental challenges.
