Summary: Following the twin floods of 1958, the Atchison community constructed a series of 25 watershed protection dams. Those dam structures remain in service to this day, although some of the operating infrastructure (valves, stems, pipes, etc…) are nearly 60 years old and require maintenance/repair/replacement.

Each dam involved in this project has a drawdown valve used to drain the body of water retained. The drawdown valves have become seized and leaky, which no longer allows the water to be drained as it was designed. This project will replace the seized drawdown valves and the drawdown pipes that leads the water to the valve to restore the original function of the dam.
