About Randall Rc&d Ca-1b-bh
The primary purpose of Randall Rc&d Ca-1b-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 John Nagel/john Deroos (local government). It impounds the Coffee Creek-tr near Niobrara Ne.
The dam stands 35 feet tall and stretches 360 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 75 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1970, the structure is well into its service life at over 50 years old.
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 04/07/1981. That was over 45 years ago.
At 35 feet, this dam is taller than 82% of dams nationwide.
