About Greg Gilbert Dam
The primary purpose of Greg Gilbert Dam is grade stabilization. Grade stabilization dams prevent erosion by reducing the slope and velocity of water flowing through a channel. They're commonly used to stop gullies from deepening and to protect downstream land and infrastructure. The dam is owned by Greg Gilbert (private). It impounds the North Hoosier Creek near Lucas.
The dam stands 32 feet tall and stretches 430 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 24 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2019, the structure is relatively new.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life.
