About Randall Rc&d Ca-66-bh
The primary purpose of Randall Rc&d Ca-66-bh 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 Ed Miedema (local government). It impounds the Missouri River-tr near Santee Ne.
The dam stands 39 feet tall and stretches 462 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 280 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1971, the structure is well into its service life at over 50 years old.
