Corte Madera, a privately owned dam located in San Diego, California, serves as a crucial water supply structure along the Tr Pine Valley Cr river. Constructed in 1919, this earth dam stands at 16 feet high with a storage capacity of 325 acre-feet, supporting both water supply and recreational purposes. With a low hazard potential and a satisfactory condition assessment as of September 2017, Corte Madera is regulated and inspected by the California Department of Water Resources (DWR) under the Safety of Dams program.

Situated in the city of Los Terrenitos, Corte Madera plays a vital role in managing water resources in the region, covering a drainage area of 2.5 square miles. Despite its age, the dam has maintained its structural integrity and safety standards, ensuring reliable water storage for the surrounding community. The dam has a surface area of 69 acres and a hydraulic height of 7.5 feet, contributing to the efficient management of water flow and storage within the reservoir.

With Juan Vargas serving as the congressional representative for the area, Corte Madera represents a key piece of infrastructure in California's water management system. The dam's last inspection in May 2020 confirmed its satisfactory condition, further solidifying its importance in providing water supply and recreational opportunities for the region. As climate change continues to impact water resources, structures like Corte Madera play a crucial role in ensuring sustainable and reliable access to water for communities in San Diego County.
