About Don Nail
The primary purpose of Don Nail 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 Don Nail (private). It impounds the Tr-fishing R. near Napoleon.
The dam stands 36 feet tall and stretches 228 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 69 acre-feet, and collects water from a drainage area of 128 square miles. Completed in 1996, the structure is 30 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.
At 36 feet, this dam is taller than 82% of dams nationwide.
