Built by the NRCS, this earth dam stands at a height of 22 feet and stretches 850 feet in length, primarily serving the purpose of debris control. Managed by the US Army, Dam 30 has a storage capacity of 135 acre-feet, with a normal storage level of 31 acre-feet and a max discharge of 610 cubic feet per second. Despite its low hazard potential, the dam has not undergone a recent condition assessment and lacks certain emergency preparedness measures.
While Dam 30 has not been modified in recent years, it operates under the supervision of the US Army, with federal funding and regulatory oversight. The dam features an uncontrolled spillway with a width of 42 feet and is primarily composed of buttress core types, supported by rock and soil foundations. Although the risk assessment for Dam 30 indicates a moderate level of risk, there are currently no detailed risk management measures in place. Overall, this structure provides vital debris control functions for the surrounding area, contributing to the management of water resources and climate resilience in the region.
