Dam profile
NID height · 27 ft27 ft tall and 400 ft long, taller than 59% of U.S. dams with a recorded height. Height is drawn to scale against a two-story house, about 25 ft; the profile is a generic embankment section and the water level is illustrative.
About B Dam
The primary purpose of B 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 Rew Ranch (private). It impounds the East Locust Creek near Pollock.
The dam stands 27 feet tall and stretches 400 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 37 acre-feet, and collects water from a drainage area of 198 square miles. Completed in 1996, the structure is 30 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.
