Nestled in Sonoma, California, Hillside Ranch stands as a testament to the importance of water resource management in the face of changing climates. Owned privately, this dam is regulated by the Department of Water Resources (DWR) for its crucial role in providing water supply for irrigation, recreation, and general use. Completed in 1967, this earth dam spans 317 feet in length and reaches a height of 60 feet, harnessing the waters of Tr House Creek to store 210 acre-feet of water for the surrounding area.

Despite its low hazard potential, Hillside Ranch maintains a satisfactory condition as of its last assessment in 2017. Regular inspections ensure its structural integrity and readiness for any emergencies, with a comprehensive Emergency Action Plan (EAP) likely in place to mitigate risks. With a minimal drainage area of 0.62 square miles, this dam serves as a vital resource for the community of Soda Springs, contributing to the sustainable management of water resources in the region.

As climate change continues to impact water availability and quality, Hillside Ranch stands as a crucial infrastructure for ensuring reliable water supply for the future. With the support of state agencies and dedicated oversight, this earth dam remains a beacon of responsible water resource management in California, catering to the needs of both the environment and the community it serves.
