About Henry Lake Dam
The primary purpose of Henry 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 Keith Henry (private). It impounds the Tr-dillon Creek near Warsaw.
The dam stands 23 feet tall and stretches 890 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 64 acre-feet, and collects water from a drainage area of 19 square miles. Completed in 1976, the structure is 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life.
