Crawford Dam, located in Oakland Mills, Iowa, was completed in 1962 and is owned and regulated by a private entity. The dam, designed by USDA NRCS, stands at 24 feet in height and spans 321 feet in length, with a primary purpose of fire protection and serving as a small fish pond. It has a storage capacity of 55 acre-feet and covers a surface area of 3.3 acres, with a drainage area of 0.23 square miles along TR-Big Cedar Creek.

With a hazard potential rated as low and a moderate risk assessment, Crawford Dam is not currently rated for its condition. The dam features an uncontrolled spillway type and is inspected by the Iowa DNR, with state permitting, inspection, and enforcement in place. While it has not been modified in recent years, the dam serves as a vital resource for water conservation and management in Jefferson County, Iowa, offering essential fire protection and supporting local wildlife with its stock and small fish pond purposes. Water resource and climate enthusiasts will appreciate the role Crawford Dam plays in the local ecosystem and its importance in maintaining a sustainable water supply for the community.
