Dittmer Dam, located in Warren County, Iowa, was completed in 1977 and serves multiple purposes including fire protection, stock watering, and small fish pond management. With a dam height of 30 feet and a length of 340 feet, the earth dam holds a normal storage capacity of 27 acre-feet and a total storage of 48 acre-feet. Situated on the TR-Mill Branch of Whitebreast Creek, the dam is regulated by the Iowa Department of Natural Resources and undergoes state inspection, permitting, and enforcement.

Managed by a private owner, Dittmer Dam was designed by the USDA NRCS and falls under the jurisdiction of the Kansas City District of the US Army Corps of Engineers. Despite being classified as having a low hazard potential, the dam is rated as moderate risk level 3, with its condition yet to be assessed. While the dam does not feature an engineered spillway, its uncontrolled spillway type poses minimal risk to downstream areas. The dam has not undergone any modification since its completion and is currently not rated in terms of condition assessment or emergency action plan preparedness.
