About Van Dyne Lake Dam
The primary purpose of Van Dyne Lake 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 John Van Dyne (private). It impounds the Sewer Branch.
The dam stands 30 feet tall and stretches 812 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 159 acre-feet, and collects water from a drainage area of 340 square miles. Completed in 1983, the structure is 43 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.
