Located in Pasadena, California, the Eaton Wash Debris Basin serves as a vital structure for debris control and flood risk reduction along the Eaton Wash river. Completed in 1936, this earth dam stands at a height of 63 feet and has a storage capacity of 721 acre-feet. With a drainage area of 9.47 square miles, the basin covers a surface area of 54 acres and plays a crucial role in managing water flow during heavy rainfall events.

Managed by the local government, this debris basin is regulated by the California Department of Water Resources and undergoes regular inspections to ensure its structural integrity. Despite its high hazard potential, the condition assessment of the Eaton Wash Debris Basin remains satisfactory, with the last inspection conducted in October 2020. In case of emergencies, the basin is equipped with emergency action plans to mitigate risks and protect surrounding communities from potential flooding.

With its strategic location and effective design, the Eaton Wash Debris Basin stands as a key component in the water resource management infrastructure of Los Angeles County. As climate change continues to impact the region, structures like this play a crucial role in safeguarding communities against the threat of floods and ensuring the sustainable use of water resources for future generations.
