Dd No 7-1a is a local government-owned dam in Brown County, Kansas, designed by Central Plains Engineering to reduce flood risks along the Squaw Creek-TR. Completed in 2001, this earth dam stands at a height of 30.1 feet and has a storage capacity of 215.4 acre-feet. With a primary purpose of flood risk reduction, it also serves for debris control, protecting the surrounding area from potential flooding events.

The dam, with a low hazard potential and moderate risk assessment, has not been inspected since its completion in 2001. Despite its condition being listed as "Not Rated," the structure is regulated by the Kansas Department of Agriculture and meets state permitting, inspection, and enforcement requirements. While there are no associated structures or outlet gates, the dam's uncontrolled spillway has a width of 40 feet, allowing for a maximum discharge of 1099 cubic feet per second in case of overflow.

Located in a critical area for flood risk, Dd No 7-1a plays a vital role in protecting the community from potential disasters. As water resource and climate enthusiasts, understanding the design, purpose, and regulatory oversight of such structures is essential for ensuring the safety and resilience of our water infrastructure in the face of changing environmental conditions.
