About Charles Pollock Dam
The primary purpose of Charles Pollock 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 Charles Pollock (private). It impounds the Tr-owl near Trenton.
The dam stands 34 feet tall and stretches 239 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 17 acre-feet, and collects water from a drainage area of 320 square miles. Completed in 1995, the structure is 31 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. The most recent inspection on record was 06/23/1995. That was over 31 years ago.
At 34 feet, this dam is taller than 78% of dams nationwide.
