About Bashor Dam No. 1
The primary purpose of Bashor Dam No. 1 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 Leroy Bashor (private). It impounds the Tr-crooked Creek near Rochester.
The dam stands 27 feet tall and stretches 290 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 30 acre-feet, and collects water from a drainage area of 294 square miles. Completed in 1993, the structure is 33 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.
