Frd No 27, also known as Little Walnut Hickory WS Dam 27, is a flood risk reduction structure located in Douglas, Kansas. Constructed in 1968 by the USDA NRCS, this earth dam stands at a height of 24 feet and has a length of 918 feet. The dam serves multiple purposes including fire protection, stock or small fish pond, and flood risk reduction, with a storage capacity of 302 acre-feet and a drainage area of 0.65 square miles.

Managed by the Kansas Dept. of Agriculture, Frd No 27 is state regulated and inspected to ensure its structural integrity and safety. The dam has a low hazard potential and a moderate risk assessment rating. Although its condition assessment is not rated, the dam continues to play a crucial role in managing water resources in the area, particularly during periods of high discharge when the uncontrolled spillway with a width of 40 feet comes into play.

Despite its age, Frd No 27 remains a vital infrastructure for flood risk reduction and water management in Butler County. With its strategic location on Plum Creek, this dam serves as a safeguard against potential flooding events, highlighting the importance of proper maintenance and regulation of water resources to mitigate climate-related risks in the region.
