About Joshua Rardin Dam
The primary purpose of Joshua Rardin 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 Joshua Rardin (private). It impounds the Trib To Thompson River near Grand River.
The dam stands 22 feet tall and stretches 462 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 117 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2017, 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.
