About Platte River Trib Watershed Dam 7-b
The primary purpose of Platte River Trib Watershed Dam 7-b 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 Platte R Trib Wtsd Subds (local government). It impounds the Tr-platte River near Parnell.
The dam stands 30 feet tall and stretches 360 feet across, creates a reservoir covering 9 acres, has a maximum storage capacity of 85 acre-feet, and collects water from a drainage area of 140 square miles. Completed in 1961, 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.
