About Speck Dam
The primary purpose of Speck 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 Paul Speck (private). It impounds the Keg Creek near Glenwood.
The dam stands 34 feet tall and stretches 220 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 26 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2004, the structure is relatively new.
