About Hamlin Dam
The primary purpose of Hamlin 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 Wallace Hamlin (private). It impounds the Tr-north Fabius River near Monticello.
The dam stands 28 feet tall and stretches 300 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 57 acre-feet, and collects water from a drainage area of 166 square miles. Completed in 1992, the structure is 34 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.
