The Haines Canyon Debris Dam, also known as the Haines Canyon Reservoir, is a critical infrastructure owned and operated by the US Army Corps of Engineers in Glendale, California. Completed in 1938, this earth dam stands at a height of 70 feet and serves the primary purpose of debris control and flood risk reduction along the Haines Creek. With a maximum storage capacity of 15 acre-feet, the dam plays a crucial role in protecting the downstream communities of Sunland-Tujunga and Glendale from potential inundation.

A recent risk assessment conducted by USACE in 2009 identified the Haines Canyon Debris Dam as having a moderate risk due to potential internal erosion issues. The dam poses a hazard with high potential consequences for over 16,600 residents and an estimated $190 million in economic impact in case of failure. To mitigate these risks, USACE has implemented various risk management measures, including conducting regular inspections, monitoring dam health, and collaborating with local emergency managers to develop and update emergency action plans. Community engagement efforts and ongoing maintenance work are also part of the proactive approach to ensure the dam's safety and functionality.

Overall, the Haines Canyon Debris Dam serves as a vital protective structure in the region, and the US Army Corps of Engineers is committed to implementing measures to reduce risks and ensure the safety of surrounding communities. Through ongoing monitoring, maintenance, and communication efforts, USACE aims to safeguard the dam and minimize the potential impacts of flood events on the downstream areas.
