Franklin Lock and Dam, located on the Caloosahatchee River in Lee, Florida, is a Federal-owned structure managed by the US Army Corps of Engineers. Completed in 1965, this multi-arch dam stands at a structural height of 31 feet and serves multiple purposes including flood risk reduction, irrigation, navigation, and recreation. With a controlled spillway width of 340 feet and a maximum discharge capacity of 28,900 cubic feet per second, the dam plays a crucial role in managing water levels and mitigating flood risks in the area.
Despite its low hazard potential, the dam is subject to regular inspections and risk assessments to ensure its structural integrity and operational readiness. The USACE actively manages flood risks associated with the dam by monitoring its condition, prioritizing maintenance activities, and collaborating with local emergency managers to develop emergency action plans and evacuation strategies. As part of their risk management efforts, the USACE also engages with the public to raise awareness about the dam and promote preparedness in the event of a dam-related emergency.
