Dittmer Dam, located in Polk County, Nebraska, serves as a crucial flood risk reduction structure along the TR-Platte River. Constructed in 1977 by the USDA NRCS, this earth dam stands at a height of 35 feet and spans 315 feet in length. With a primary purpose of flood risk reduction, Dittmer Dam has a normal storage capacity of 17 acre-feet and a maximum storage of 290 acre-feet, providing essential protection to the surrounding area.

Managed by the local government and regulated by the Nebraska Department of Natural Resources, Dittmer Dam has a low hazard potential and is deemed to be in satisfactory condition as of its last inspection in 2017. The dam's structure, primarily made of stone core on a soil foundation, is designed to handle a maximum discharge of 44 cubic feet per second. Despite its critical role in mitigating flood risks, the dam has not been modified in recent years and undergoes inspections every five years to ensure its continued effectiveness.

Dittmer Dam's location within the Kansas City District and its designation as a state-regulated dam highlight its importance in water resource management. With its strategic positioning and capacity to safeguard against flooding, Dittmer Dam stands as a testament to the collaborative efforts of government agencies and designers in protecting communities and maintaining the integrity of water resources in Nebraska.
