About Hiatt Lake Dam
The primary purpose of Hiatt Lake 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 Burton Hiatt (private). It impounds the Tr-bee Creek near Weston.
The dam stands 34 feet tall and stretches 220 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 36 acre-feet, and collects water from a drainage area of 12 square miles. Completed in 1978, the structure is 48 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.
At 34 feet, this dam is taller than 78% of dams nationwide.
