About Shahan Dam
The primary purpose of Shahan 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 Lyle Shahan (private). It impounds the Tr-bear Creek near Louisiana.
The dam stands 26 feet tall and stretches 362 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 47 acre-feet, and collects water from a drainage area of 155 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.
