Highland Creek, also known as Highland Springs Reservoir, is a vital water resource in Lake County, California. Managed by a public utility, this dam was completed in 1962 with the primary purpose of flood risk reduction. With a height of 75 feet and a storage capacity of 3500 acre-feet, Highland Creek plays a crucial role in water supply and recreation for the local community.

Located in the city of Finley, Highland Creek is regulated by the Department of Water Resources and undergoes regular inspections to ensure its structural integrity. The dam has a high hazard potential, but its condition assessment in 2017 deemed it satisfactory. With a drainage area of 14.15 square miles and a surface area of 72 acres, the reservoir serves as a significant source of water for the surrounding region.

Constructed by the USDA NRCS, Highland Creek stands as a testament to effective flood control and water management in California. Its presence not only reduces the risk of flooding but also provides opportunities for recreational activities and sustainable water supply. As climate change continues to impact water resources, the importance of structures like Highland Creek in ensuring water security and resilience cannot be understated.
