Gs Dd No C-125 is a local government-owned earth dam located in Valley Falls, Kansas, with a primary purpose of flood risk reduction. Built in 1990 by designer King & Associates, the dam stands at a height of 30 feet and spans 445 feet in length, with a maximum storage capacity of 108.9 acre-feet. Situated on Elk Creek, the dam serves to control debris and mitigate flood risks in the surrounding area.

Maintained by the Kansas Department of Agriculture, Gs Dd No C-125 has a low hazard potential and has not been rated for its current condition. Despite its moderate risk assessment rating, the dam does not have an emergency action plan in place, and its last inspection date is unknown. With a drainage area of 0.25 square miles and a maximum discharge capacity of 756 cubic feet per second, the dam plays a vital role in water resource management for the local community.

Although Gs Dd No C-125 has not been modified in recent years and lacks outlet gates, it continues to provide essential flood protection and debris control for the area. With its uncontrolled spillway and moderate risk assessment rating, it is crucial for local authorities to prioritize regular inspections and maintenance to ensure the dam's continued effectiveness in safeguarding against potential flood events and preserving the surrounding watershed.
