The Cherry Creek Dam outlet manages reservoir levels by releasing water from the reservoir to downstream users. Release rates are generally less than 100 cubic feet of water per second. The outlet structure can release water at a rate of up to 10,000 cfs. when operating to reduce flood risks during periods of high runoff. One cubic foot of water, or cfs, is equivalent to 7.5 gallons. — Cherry Creek Dam Outlet Structure

Flood Risk Feasibility Study for Atchison and Nemaha counties 01.15.25

ROCK PORT, Mo. -- Col. Robert J. Newbauer, U.S. Army Corps of Engineers (USACE), Omaha District, commanding officer, center, signs a project agreement announcement along with representatives from the Missouri Department of Natural Resources (DNR) and Nebraska DNR, who have partnered with the USACE in a feasibility study to assess flood risk management measures along the Missouri River in Nemaha County, Nebraska, and Atchison County, Missouri, on Jan. 15, 2025. The study is expected to provide valuable insights into floodplain management, navigation, and habitat restoration, which are essential for the communities and ecosystems along this reach of the Lower Missouri River. By pooling resources and expertise, the Omaha District and state agencies will work with public stakeholders to explore feasible flood prevention measures. This feasibility study will last approximately three years and will end with a recommended plan.
