Located in the Mission Creek watershed in Kansas, Frd No 5b (Mission Creek) is a critical earth dam constructed in 1975 by the USDA NRCS for the primary purpose of flood risk reduction. With a height of 42 feet and a length of 1730 feet, this dam plays a vital role in controlling the flow of Mission Creek-TR during periods of heavy rainfall. The dam has a storage capacity of 469.8 acre-feet and covers a surface area of 10.69 acres, serving a drainage area of 1.1 square miles.

Despite its importance in flood risk management, Frd No 5b has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam features an uncontrolled spillway with a width of 40 feet and no outlet gates. While the risk assessment for the dam is considered moderate, there is no Emergency Action Plan (EAP) in place, and the last inspection date is unknown. With its crucial role in mitigating flood risks in the Mission Creek watershed, ongoing monitoring and maintenance of Frd No 5b are essential to ensure its continued effectiveness and safety for the community of Oketo and surrounding areas.
