Kilbourn, also known as Wisconsin Dells, is a privately owned hydroelectric facility located in the beautiful state of Wisconsin. This gravity dam was completed in 1909 and boasts a height of 61 feet, with a primary purpose of generating hydroelectric power and providing recreational opportunities. The dam has a storage capacity of 36,000 acre-feet and serves a drainage area of 7,746 square miles, with a maximum discharge of 80,690 cubic feet per second.

The Kilbourn dam has a controlled spillway and a high hazard potential, but its condition assessment is satisfactory, with the last inspection in July 2020. The risk assessment for this dam is classified as very high (1), indicating the need for strong risk management measures. The dam is regulated and inspected by the Wisconsin Department of Natural Resources, ensuring that it meets state permitting, inspection, and enforcement requirements. Kilbourn's location on the Wisconsin River in Columbia County makes it a critical water resource that must be carefully managed for the safety and well-being of the surrounding communities and the environment.
