About Odoherty Dam
The primary purpose of Odoherty 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 Lindsey Odoherty (private). It impounds the Unnamed Trib To Indian Creek near Emerson.
The dam stands 19 feet tall and stretches 630 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 70 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2024, 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.
