About Newquist Grade Stabilization Structure
The primary purpose of Newquist Grade Stabilization Structure 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 Ron Newquist & William Durflinger (private). It impounds the Trib To Buckeye Creek near Fairfield.
The dam stands 27 feet tall and stretches 569 feet across, creates a reservoir covering 21 acres, has a maximum storage capacity of 612 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 2011, 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.
