Lake Sherwood, located in Thousand Oaks, California, is a privately owned reservoir primarily used for water supply purposes. With a dam height of 45 feet and a storage capacity of 2600 acre-feet, this arch-type dam was completed in 1904 and stands as a crucial water resource in Ventura County. The lake covers an area of 163 acres and is fed by the Potrero Valley Creek.

Despite its age, Lake Sherwood has undergone regular inspections and is deemed to be in satisfactory condition, with a high hazard potential. The dam is regulated by the California Department of Water Resources and undergoes regular permitting, inspection, and enforcement to ensure its safety and functionality. The surrounding area offers opportunities for irrigation, recreation, and of course, water supply.

As climate change continues to impact water resources, Lake Sherwood serves as a vital asset in the region's water management infrastructure. Its historical significance, coupled with its modern regulatory oversight, highlights the importance of maintaining and preserving such critical water sources in the face of a changing climate.
