The Pacoima Dam is a concrete arch dam located in the San Fernando Valley of California. Completed in 1939, it was built to provide flood control and water supply for the surrounding areas. The dam creates the Pacoima Reservoir, which helps manage water flow and supports local ecosystems. Standing at 185 feet tall, the dam is part of the Los Angeles County Flood Control District and plays a crucial role in preventing flooding during heavy rains. It also contributes to the region's water supply, making it an important infrastructure element for the community.
