Mill Pond, located in Mendocino, California, is a privately owned earth dam completed in 1885 with a primary purpose of water supply. The dam stands at a height of 33 feet, with a hydraulic height of 30.6 feet, and a storage capacity of 72 acre-feet. Situated on Alder and Maple Creek, the dam serves as a vital resource for the surrounding area, with a drainage area of 0.45 square miles and a surface area of 9 acres.

Managed by the California Department of Water Resources (DWR) under the Safety of Dams program, Mill Pond is subject to regular state inspection, enforcement, and permitting to ensure its safety and compliance with regulations. Despite its age, the dam has been assessed to be in fair condition with a low hazard potential, indicating a relatively low risk to the surrounding community in case of a potential failure. The last inspection in May 2020 found the dam to be in satisfactory condition, further reinforcing its importance as a reliable water source in the region.

With its historical significance dating back over a century and its continued role in providing water supply, Mill Pond stands as a testament to the enduring importance of water resource management and infrastructure. Climate and water resource enthusiasts can appreciate the careful oversight and maintenance of this dam, ensuring its continued functionality and safety for the community it serves.
