Built in 1962 by the USACE, this concrete dam stands at a height of 10 feet and serves various purposes, including flood control and water storage. With a normal storage capacity of 1050 acre-feet and a maximum discharge of 75 cubic feet per second, G-72 plays a vital role in regulating water flow in the C-7 Extension Canal.
Managed by the Florida Department of Environmental Protection (FDEP), G-72 is state-regulated and undergoes regular inspections, permitting, and enforcement to ensure its structural integrity and functionality. With a low hazard potential and a risk assessment rating of "Very High (1)", this dam is classified as a critical infrastructure with high-risk management measures in place. Despite its condition assessment being listed as "Not Rated", G-72 remains a key component in the water resource management of the region.
As a part of the Jacksonville District of the USACE, G-72 is equipped with a controlled spillway and vertical lift outlet gates to efficiently manage water levels and mitigate potential risks. While specific details regarding its last inspection date and emergency action plan preparation are not provided, the structure's strategic location and design highlight its importance in the overall water resource management and climate resilience efforts in the area.
