About Merrill Dorland Dam
The primary purpose of Merrill Dorland 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 Merrill Dorland (private). It impounds the Tr - West Lake near West Lake.
The dam stands 31 feet tall and stretches 332 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 31 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2014, the structure is relatively new.
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.
