Deer Canyon Debris Basin, located in Alta Loma, California, serves as a vital structure for debris control and flood risk reduction along Deer Creek. This earth dam, completed in 1980, stands at a height of 78 feet and has a hydraulic height of 58.5 feet. With a storage capacity of 24 acre-feet and covering a surface area of 3 acres, this basin plays a crucial role in managing runoff and protecting the surrounding area from potential hazards.

Managed by a local government entity, Deer Canyon Debris Basin is regulated by the Department of Water Resources (DWR) under the Safety of Dams program. The dam has been deemed to have a high hazard potential, but its condition assessment as of September 2017 was rated as satisfactory. Regular inspections are conducted, with the last inspection taking place in December 2019. While the structure meets guidelines for emergency action planning, there is room for improvement in risk assessment and management measures. Overall, Deer Canyon Debris Basin stands as a critical infrastructure for safeguarding the community against the impacts of extreme weather events and ensuring the sustainable management of water resources in the region.
