About B. Williams Lake Dam No 1
The primary purpose of B. Williams Lake Dam No 1 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 Billie Williams (private). It impounds the Tr-honey Creek near Warsaw.
The dam stands 22 feet tall and stretches 600 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 172 acre-feet, and collects water from a drainage area of 384 square miles. Completed in 1977, the structure is 49 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.
