Frd No 30, also known as Little Walnut Hickory WS Dam 30, is a vital flood risk reduction structure located in Butler County, Kansas. Constructed in 1967 by the USDA NRCS, this earth dam stands at a height of 29.5 feet and spans 900 feet in length. It serves the primary purpose of flood risk reduction along the Honey Creek, with a normal storage capacity of 46 acre-feet and a maximum storage of 657.47 acre-feet.

Managed by the local government, Frd No 30 is regulated by the Kansas Department of Agriculture and undergoes state inspection, permitting, and enforcement. The dam has a low hazard potential and is rated as not yet assessed for condition.
