Wilson Debris Basin, located in Los Angeles, California, was completed in 1961 and serves as a crucial structure for debris control and flood risk reduction along Wilson Canyon. Owned by the local government, this earth dam stands at a height of 50 feet with a hydraulic height of 33 feet, providing a storage capacity of 84 acre-feet. With a hazardous potential rated as high, the dam's condition was last assessed as satisfactory in September 2017, indicating its reliability in managing potential risks associated with heavy debris and flooding events.
Managed by the California Department of Water Resources, Wilson Debris Basin is regulated and inspected regularly to ensure its operational effectiveness and structural integrity. The dam's location in a densely populated area underscores its importance in protecting downstream communities from the impacts of debris flows and flooding. With a drainage area of 2.6 square miles and a surface area of 5 acres, the basin plays a critical role in mitigating the potential hazards posed by debris-laden runoff during heavy rainfall events.
The structural design, storage capacity, and historical significance of Wilson Debris Basin make it a vital component of the local flood control system in Los Angeles. As climate change continues to influence precipitation patterns and extreme weather events, the maintenance and upkeep of this debris control structure are essential for safeguarding both property and lives in the surrounding area. The dam's strategic location and purposeful design highlight its role as a key asset in water resource management and climate resilience efforts within the region.
