Jersey is a captivating hydroelectric dam located in Tomahawk, Wisconsin, along the picturesque Tomahawk River. Built in 1929 by Byllesby, this gravity dam stands at a height of 34 feet and has a structural height of 28 feet, providing essential power generation and flood control capabilities. With a normal storage capacity of 1594 acre-feet and a maximum discharge of 24000 cubic feet per second, Jersey plays a crucial role in managing water resources in the region.

Owned by a Public Utility and regulated by the Federal Energy Regulatory Commission, Jersey is a vital piece of infrastructure with a high hazard potential due to its location and design. The dam boasts a controlled spillway and various outlet gates, including a slide gate and four radial gates, ensuring efficient water flow management. Despite its age, the dam's risk assessment ranks as very high, highlighting the importance of ongoing monitoring and maintenance to ensure its continued safe operation.

Visitors to Jersey can admire its multi-arch design and rock foundation, as well as the beautiful surrounding area of Lincoln County, Wisconsin. With its rich history and significant role in water resource management, Jersey stands as a testament to the intersection of engineering excellence and environmental stewardship in the face of climate challenges.
