About Gray Lake Dam
The primary purpose of Gray Lake 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 Cecil Gray (private). It impounds the Tr-honey Creek near Warsaw.
The dam stands 26 feet tall and stretches 810 feet across, creates a reservoir covering 10 acres, has a maximum storage capacity of 368 acre-feet, and collects water from a drainage area of 175 square miles. Completed in 1976, the structure is 50 years old.
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.
