Managed by the South Florida Water Management District (SFWMD), this state-regulated structure plays a vital role in managing water levels in the Zipperer Canal to prevent flooding and protect surrounding areas. With a dam height of 15 feet and a hydraulic height of 9 feet, the G103 Control Structure has a structural height of 24 feet and was completed in 1965.
Covering a drainage area of 42 square miles, the G103 Control Structure has a maximum storage capacity of 49,000 acre-feet and a normal storage level of 35,100 acre-feet, serving a surface area of 5,400 acres. Equipped with a controlled spillway with a width of 50 feet, this structure has a maximum discharge capacity of 734 cubic feet per second. Despite its low hazard potential, the risk assessment for the G103 Control Structure indicates a very high risk level, emphasizing the importance of its maintenance and monitoring for optimal performance in mitigating flood risks in the region.
The G103 Control Structure stands as a testament to Florida's commitment to water resource management and climate resilience. With its roller-compacted concrete core type and soil foundation, this structure exemplifies the state's efforts to prioritize flood risk reduction and ensure the safety of its residents. As climate change continues to impact water resources, the G103 Control Structure remains a crucial asset in safeguarding the surrounding communities and enhancing the overall resilience of the region against potential flooding events.
