Jordahl, located in Rockbridge, Wisconsin, is a privately owned earth dam completed in 1973 for fire protection, stock, or small fish pond purposes. The dam stands at a height of 30 feet with a hydraulic height of 26 feet and a length of 240 feet. With a drainage area of 0.1 square miles and a normal storage capacity of 11 acre-feet, Jordahl serves as a vital water resource for the surrounding area.

This dam on an unnamed tributary to the Pine River has a high hazard potential and a fair condition assessment as of May 2020. Despite its age, Jordahl continues to play a crucial role in water management and disaster prevention, with a maximum discharge capacity of 85 cubic feet per second. The dam's controlled spillway and updated inspections ensure its safety and functionality for the community it serves.

With its location in a high-risk area and a very high risk assessment rating, Jordahl is closely monitored by the Wisconsin Department of Natural Resources. The dam's emergency action plan, if prepared, could provide essential guidelines for responding to potential incidents. As climate change increases the frequency and intensity of extreme weather events, the maintenance and proper management of dams like Jordahl are essential for safeguarding communities and water resources in Wisconsin.
