Doyle, also known as Alpine Lake, is a privately-owned water resource located in Juneau, Wisconsin. Managed by the Wisconsin Department of Natural Resources, this dam serves primarily for recreational purposes and was completed in 1970. Standing at 48 feet tall with a hydraulic height of 35 feet, Doyle has a maximum storage capacity of 250 acre-feet and covers an area of 11 acres.

Despite its low hazard potential, Doyle's condition assessment in 2013 deemed it unsatisfactory, highlighting the need for maintenance and repairs. The dam's risk assessment was classified as very high, emphasizing the importance of implementing effective risk management measures. With a drainage area of 0.4 square miles and a controlled spillway type, Doyle plays a crucial role in managing water flow and protecting downstream areas along TR Cleaver Creek.

In the care of private owners, Doyle represents both the beauty and responsibility of stewarding water resources in the face of climate challenges. Its historical significance as a recreational spot intertwines with the imperative of ensuring its structural integrity for future generations to enjoy and benefit from. As enthusiasts of water resources and climate conservation, understanding and advocating for the maintenance and safety of dams like Doyle is essential in safeguarding our environment and communities.
