With a moderate risk assessment rating, Branched Oak Dam is equipped with uncontrolled spillways and has a hazard potential classified as high. The USACE implements various risk management measures to mitigate potential threats, including regular inspections, maintenance, and emergency action planning. The dam plays a crucial role in managing water levels along Oak Creek and can release water to maintain structural integrity or relieve pressure during severe weather events. Continuous monitoring and collaboration with local emergency managers ensure preparedness and response in case of dam-related emergencies.
