Oxford Mill Dam, located on the Wapsipinicon River in Jones County, Iowa, is a historic structure completed in 1927 by the local government. With a height of 9 feet and a length of 290 feet, the dam serves a primary purpose of "Other" and has a storage capacity of 163 acre-feet. Despite not being rated for its condition, the dam is considered to have low hazard potential.

The dam is state regulated by the Iowa Department of Natural Resources, with permitting, inspection, and enforcement all carried out by the state agency. The structure is not owned or funded by any federal agency and does not fall under the jurisdiction of the US Army Corps of Engineers. While the dam has not been modified in recent years and lacks certain emergency preparedness measures such as an Emergency Action Plan, its risk assessment and management measures are currently unspecified. Water resource and climate enthusiasts may find Oxford Mill Dam to be an intriguing case study in the management and regulation of small-scale dams in the Midwest.
