Located in Monterey, California, the Coleman Dam, also known as Dam #1, serves multiple purposes including fire protection, stock, and small fish pond management. Owned and operated by the US Army, this earth dam stands at a height of 27 feet with a hydraulic height of 20 feet. Completed in 1965, it has a storage capacity of 80 acre-feet and covers a surface area of 11 acres along Coleman Creek.

With a low hazard potential and a moderate risk assessment rating, the Coleman Dam is primarily used for recreational activities and maintaining local wildlife habitats. Despite its age, the dam remains in good condition with inspections conducted every four years by the US Army. The surrounding area, including the city of Jolon, benefits from the water resources provided by this structure, ensuring water availability for various needs while also contributing to the conservation of the local environment.
