About Thomas Site
The primary purpose of Thomas Site 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 Marmaton Wjd No 102 (local government). It impounds the Marmaton River-tr near Fort Scott.
The dam stands 45 feet tall and stretches 878 feet across, creates a reservoir covering 19 acres, has a maximum storage capacity of 660 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 2012, the structure is relatively new.
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. The most recent inspection on record was 09/30/2011. That was over 14 years ago.
