Built in 1961 by the US Army Corps of Engineers, this rockfill dam towers at a height of 110 feet with a hydraulic height of 115 feet, serving a crucial purpose in safeguarding surrounding communities from catastrophic flooding. With a storage capacity of 131,000 acre-feet and a maximum discharge of 28,500 cubic feet per second, the dam plays a pivotal role in mitigating flood risks in the region.
Despite being classified as having a high hazard potential, the risk of dam failure is deemed moderate, primarily due to the significant downstream population it protects. However, the possibility of uncontrolled water releases from the spillway during extreme storm events remains a concern. The US Army Corps of Engineers actively manages these risks through regular inspections, maintenance, and coordination with local emergency managers to ensure readiness in case of an emergency. While the likelihood of a catastrophic dam failure is minimal, the potential impact on downstream communities underscores the importance of ongoing risk management measures to safeguard lives and property in the event of a worst-case scenario.
