Oak Street Dam, located in Corona, California, is a key structure managed by local government for flood risk reduction along Oak Street Creek. Completed in 1979, this earth dam stands at a height of 36 feet and has a storage capacity of 138 acre-feet. With a drainage area of 6.02 square miles, the dam plays a crucial role in protecting the surrounding area from potential inundation and managing water flow during heavy rainfall events.

Managed by the California Department of Water Resources and regulated by the Safety of Dams agency, Oak Street Dam has a high hazard potential but is currently assessed to be in satisfactory condition. The dam's last inspection in January 2020 showed that it meets safety standards, with an inspection frequency of once per year. Despite its age, Oak Street Dam continues to fulfill its primary purpose of flood risk reduction effectively, highlighting the importance of consistent monitoring and maintenance to ensure its long-term resilience in the face of changing climate patterns.
