About David Cochran Dam
The primary purpose of David Cochran 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 David Cochran (private). It impounds the Tr-big No Creek near Farmersville.
The dam stands 29 feet tall and stretches 456 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 46 acre-feet, and collects water from a drainage area of 172 square miles. Completed in 1990, the structure is 36 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 01/19/1989. That was over 37 years ago.
