About Prague Lake
The primary purpose of Prague Lake is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by City Of Prague (local government). It impounds the Sand Creek.
The dam stands 45 feet tall and stretches 1,460 feet across, creates a reservoir covering 225 acres, has a maximum storage capacity of 5,656 acre-feet, and collects water from a drainage area of 6 square miles. Completed in 1984, the structure is 42 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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. The most recent inspection on record was 12/23/2015. That was over 10 years ago.
At 45 feet, this dam is taller than 91% of dams nationwide.
