About J. W. Harding
The primary purpose of J. W. Harding 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 Harding (private). It impounds the Little Rock Creek near Denver.
The dam stands 28 feet tall and stretches 295 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 23 acre-feet, and collects water from a drainage area of 115 square miles. Completed in 1999, the structure is 27 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.
