About Rasmussen Dam
The primary purpose of Rasmussen 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 Dtl Farms (private). It impounds the Tributary To Fletcher Branch near Patterson.
The dam stands 33 feet tall and stretches 409 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 57 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2020, 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.
At 33 feet, this dam is taller than 78% of dams nationwide.
