Dimick Dam, located in Jefferson County, Iowa, was completed in 1985 by the USDA NRCS and is privately owned. This earth dam stands at a height of 29 feet and has a length of 595 feet, creating a reservoir with a normal storage capacity of 47 acre-feet for purposes such as fire protection and small fish pond management. The dam, situated on TR-BRUSH CR., has a low hazard potential and is currently assessed as being in a moderate risk category.

Managed by the Iowa Department of Natural Resources, Dimick Dam is subject to state regulations, inspections, and enforcement. Although the dam does not have a spillway, its uncontrolled design allows for the release of excess water in the event of heavy rainfall. With a drainage area of 0.18 square miles, the dam serves as a valuable water resource for the surrounding area, supporting agricultural and ecological needs. Despite its low hazard potential, the dam's condition is currently not rated, highlighting the importance of ongoing monitoring and maintenance efforts to ensure its safety and functionality for the community.
