Standing at 14 feet high with a storage capacity of 200 acre-feet, G-58 serves multiple purposes, including flood control and water storage. The dam is regulated by the Florida Department of Environmental Protection (FDEP) and undergoes regular inspections and enforcement to ensure its safety and functionality.
With a spillway width of 23 feet and a controlled spillway type, G-58 has a significant hazard potential and is considered to have a very high risk level. Despite its age, the dam's condition assessment is not rated, indicating a need for further evaluation. Emergency action plans (EAP) and risk management measures for G-58 are currently not prepared or updated, raising concerns about the response capabilities in the event of a failure. It is crucial for water resource and climate enthusiasts to monitor and advocate for the proper maintenance and management of G-58 to ensure the safety of downstream communities and the environment.
