Bailey Debris Basin, located in Sierra Madre, California, is a crucial structure designed for debris control and flood risk reduction along Bailey Can Wash. Built in 1954, this earth dam stands at a height of 43 feet and spans a length of 585 feet, with a maximum storage capacity of 49 acre-feet. Despite its age, the dam is in satisfactory condition, as assessed in September 2017, and is regulated, inspected, and enforced by the Department of Water Resources (DWR) for safety compliance.

With a hazard potential rated as high, Bailey Debris Basin plays a vital role in protecting the surrounding area from potential flooding and debris flow events. The dam's ability to hold back sediment and large debris during heavy rainfall events helps to mitigate the risk of downstream flooding and property damage. Regular inspections and a comprehensive emergency action plan ensure that the structure is well-maintained and prepared to respond effectively in case of an emergency.

Managed by the local government, Bailey Debris Basin serves as a key component of the flood control infrastructure in Los Angeles County. Its strategic location and design provide a valuable defense against the impact of extreme weather events, safeguarding lives and properties in the region. Water resource and climate enthusiasts can appreciate the important role that structures like Bailey Debris Basin play in enhancing community resilience and reducing the impact of natural disasters on vulnerable areas.
