About Holly 10
The primary purpose of Holly 10 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 Kassel, Ron (private). It impounds the Plum Creek-tr near Walnut Grove.
The dam stands 46 feet tall and stretches 150 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 31 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2023, the structure is relatively new.
