About Howard Watson Structure Dam
The primary purpose of Howard Watson Structure 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 Howard Watson (private). It impounds the Tr-white Cloud Creek near Bolkcow.
The dam stands 27 feet tall and stretches 600 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 41 acre-feet, and collects water from a drainage area of 188 square miles. Completed in 1959, the structure is well into its service life at over 50 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.
