About Hendrick Lake Dam

The primary purpose of Hendrick 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 Clifford Hendrick (private). It impounds the Tr-marshalls Creek near Warsaw.

The dam stands 21 feet tall and stretches 80 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 109 acre-feet, and collects water from a drainage area of 96 square miles. Completed in 1975, 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.
