About Grindstone-lost-muddy Watershed Dam D-31
The primary purpose of Grindstone-lost-muddy Watershed Dam D-31 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 Grdns-ls-mdy Wsd Subdist (local government). It impounds the Tr-e.fork Lost Creek near Pattonsburg.
The dam stands 25 feet tall and stretches 500 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 121 acre-feet, and collects water from a drainage area of 275 square miles. Completed in 1975, 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.
