Rager Dam, located in Missouri Valley, Iowa, is a private dam designed by the USDA NRCS with a primary purpose of flood risk reduction. Completed in 2011, this earth dam stands at a height of 58 feet and spans 550 feet in length, with a maximum storage capacity of 102 acre-feet. The dam serves multiple purposes including fish and wildlife pond, grade stabilization, and recreation, while also regulating the flow of a tributary to Elk Creek.

Managed by the Iowa Department of Natural Resources, Rager Dam has a low hazard potential and has not been rated for its condition assessment. Despite its primary function of flood risk reduction, the dam also provides opportunities for recreational activities and supports wildlife habitats. With its strategic location and efficient design, Rager Dam plays a vital role in water resource management and climate resilience efforts in the region, contributing to the overall environmental sustainability and safety of the area.
