Gs Dd No 6-33 is a local government-owned earth dam located in Nemaha, Kansas, designed by Duane Mueting and completed in 1996. The dam serves primarily for debris control and flood risk reduction purposes along Wolfley Creek-TR. With a height of 25 feet and a length of 408 feet, the dam has a storage capacity of 41.88 acre-feet and a surface area of 1.8 acres, effectively managing a drainage area of 0.16 square miles.

Despite being rated as having a low hazard potential and a moderate risk assessment, Gs Dd No 6-33 has not undergone a formal condition assessment and is currently marked as "Not Rated". The dam features an uncontrolled spillway with a width of 30 feet and no outlet gates. While it has not been inspected since its completion in 1996, the dam's emergency action plan status, risk management measures, and compliance with guidelines remain unspecified. With its strategic location and critical role in flood risk reduction, Gs Dd No 6-33 stands as a significant infrastructure asset in the region, deserving of continued monitoring and potential improvements to ensure its long-term effectiveness and safety.
