Completed in 1997 by King Engineering, this dam stands at a height of 25 feet and spans a length of 700 feet, with a storage capacity of 143.3 acre-feet. While the dam primarily serves the purpose of flood risk reduction, it also aids in debris control to safeguard the surrounding area from potential hazards during severe weather events.

The dam has no outlet gates and features an uncontrolled spillway with a width of 30 feet. Despite its lack of state regulation, inspection, and enforcement, the dam has a solid emergency action plan in place to respond to any potential risks or emergencies, ensuring the safety of the community in the event of a flood or other catastrophic event. Overall, Gs Dd No F-9 plays a vital role in protecting the residents and infrastructure of Meriden, Kansas, from the impacts of flooding and serves as a critical component of the local water resource management system.
