About Henselman Dam
The primary purpose of Henselman 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 Robert Henselman (private). It impounds the Tr-south Wyaconda near Arbela.
The dam stands 37 feet tall and stretches 420 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 56 acre-feet, and collects water from a drainage area of 19 square miles. Completed in 2004, 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. The most recent inspection on record was 11/01/2004. That was over 21 years ago.
At 37 feet, this dam is taller than 83% of dams nationwide.
