Built in 1920 and owned by the state, this dam on the Hillsboro Canal serves a primary purpose classified as "Other." It stands at a structural height of 37 feet, with a hydraulic height of 19 feet and a length of 125 feet.
With a maximum storage capacity of 2100 acre-feet and a normal storage capacity of 1405 acre-feet, G-56 has a surface area of 200 acres and drains an area of 75 square miles. The dam has a controlled spillway with a width of 20 feet and a maximum discharge rate of 1600 cubic feet per second. While the dam is currently rated as "Not Rated" in terms of its condition assessment, it undergoes regular state inspections, permitting, and enforcement to ensure its safety and functionality.
Climate and water resource enthusiasts would be intrigued by G-56's unique design and historical significance, as well as its critical role in managing water flow in the region. The dam's location in the Boca Raton Delimited Area and its association with the Jacksonville District of the US Army Corps of Engineers add to its importance in the local ecosystem. Despite its low hazard potential, the very high risk assessment underscores the need for ongoing risk management measures and emergency preparedness to safeguard the surrounding communities and water resources.
