Dd No 8-30 is a local government-owned dam located in Peoria, Kansas, along the Tauy Creek. Built in 1995 by designer Dale Steward, P.E., this earth dam stands at a height of 24 feet and stretches 800 feet in length. Its primary purpose is flood risk reduction, with debris control also being a key focus. The dam has a storage capacity of 222.41 acre-feet and covers a surface area of 10.1 acres, serving a drainage area of 0.63 square miles.

Despite its low hazard potential, Dd No 8-30 is regulated, inspected, and permitted by the Kansas Department of Agriculture, indicating a commitment to maintaining safety standards. The dam features an uncontrolled spillway with a width of 40 feet and has a maximum discharge capacity of 552 cubic feet per second. While the dam is in moderate risk (level 3) according to a risk assessment, its overall condition is currently not rated. Its location in Douglas County, Kansas, under the jurisdiction of the state, highlights the importance of effective water resource management in the region.
