About Comley Dam
The primary purpose of Comley 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 Ronnie Comley (private). It impounds the Tr-middle Fabius River near Monticello.
The dam stands 33 feet tall and stretches 200 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 20 acre-feet, and collects water from a drainage area of 160 square miles. Completed in 2006, 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. The most recent inspection on record was 09/30/2006. That was over 19 years ago.
At 33 feet, this dam is taller than 78% of dams nationwide.
