Dubay, located in Portage, Wisconsin, is a privately-owned concrete dam on the Wisconsin River with a primary purpose of hydroelectric power generation. Completed in 1942, this impressive structure stands at a height of 40 feet and has a maximum storage capacity of 128,800 acre-feet, serving flood risk reduction and energy production needs. With a spillway width of 330 feet and a controlled spillway type, Dubay boasts a high hazard potential and a very high risk assessment rating.

Managed by the Federal Energy Regulatory Commission, Dubay is not state-regulated but has state permitting and enforcement in place. The dam's condition assessment is currently not available, but emergency action plans are in preparation to ensure public safety in case of any unforeseen events. Despite its age, Dubay continues to play a vital role in water resource management, with a drainage area of 4,822 square miles and a maximum discharge capacity of 150,000 cubic feet per second.

Water resource and climate enthusiasts will appreciate the engineering marvel that is Dubay, as it combines the functionality of flood risk reduction with sustainable hydroelectric power generation. The dam's association with the Wisconsin River and its pivotal location in Stevens Point make it a key player in the region's water management infrastructure. As efforts continue to assess and mitigate potential risks associated with the dam, Dubay stands as a testament to the importance of effective water resource management in Wisconsin.
