About Robert Phillips Dam
The primary purpose of Robert Phillips 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 Robert Phillips (private). It impounds the Tributary to Fivemile Creek.
The dam stands 23 feet tall and stretches 450 feet across, has a maximum storage capacity of 66 acre-feet, and collects water from a drainage area of 5 square miles. Completed in 2017, 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.
