About Troublesome Creek Watershed Site 85-1
The primary purpose of Troublesome Creek Watershed Site 85-1 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 Audubon County Swcd (local government). It impounds the Tr- East Nishnabotna River near Brayton.
The dam stands 25 feet tall and stretches 508 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 118 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 2003, 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.
