Bloomer Mill, located in Chippewa, Wisconsin, is a historic gravity dam on Duncan Creek that was completed in 1856 for recreational purposes. With a height of 17 feet and a length of 460 feet, the dam has a maximum storage capacity of 945 acre-feet and serves as a vital water resource for the surrounding area. The dam has a controlled spillway type and a high hazard potential, which necessitates regular inspections and maintenance to ensure public safety.

Despite its age, Bloomer Mill is in satisfactory condition according to the most recent assessment conducted in February 2019. The dam has undergone modifications in 1909 and 2004 to improve its structural integrity and performance. The risk assessment of the dam indicates a very high risk level (level 1), prompting the need for robust risk management measures to mitigate potential hazards and ensure the continued safety and functionality of the dam. The dam is regulated by the Wisconsin Department of Natural Resources and is subject to state permitting, inspection, and enforcement to uphold safety standards and compliance with regulations.
