Haldeman is a privately owned earth dam located in Monroe, Wisconsin, along the TR-Morris Creek. Completed in 1971, the dam serves multiple purposes, including fire protection, stock watering, and small fish pond management. With a structural height of 28 feet and a length of 340 feet, Haldeman has a storage capacity of 16 acre-feet and covers a surface area of 1 acre, draining a 0.6 square mile watershed.

Despite being classified as having a low hazard potential, Haldeman is regularly inspected by the Wisconsin Department of Natural Resources, with the most recent assessment in March 2021 indicating a fair condition. The dam features an uncontrolled spillway and a maximum discharge capacity of 120 cubic feet per second. While the risk assessment is moderate, with a rating of 3 out of 5, there are currently no documented emergency action plans in place for the structure.

Overall, Haldeman serves as a vital water resource in the region, contributing to fire protection and ecosystem management. As climate change continues to impact water availability and quality, it is crucial to maintain and monitor structures like Haldeman to ensure their long-term functionality and safety for both human and environmental well-being.
