Twin Falls, also known as Michigamme, is a privately owned hydroelectric dam located in Aurora, Wisconsin. Built in 1912 on the Menominee River, this gravity dam stands at 56 feet tall with a hydraulic height of 44 feet and a structural height of 56 feet. The dam has a storage capacity of 10,000 acre-feet and covers a surface area of 1120 acres, serving both hydroelectric and recreational purposes.

With a maximum discharge of 40,480 cubic feet per second, Twin Falls has a controlled spillway and is classified as having a high hazard potential. Despite its age, the dam's condition assessment is not rated, indicating the need for further inspection and evaluation. The risk assessment for Twin Falls is very high, warranting risk management measures to ensure the safety and stability of the structure.

As a significant part of the hydroelectric infrastructure in the region, Twin Falls plays a crucial role in both water resource management and climate adaptation efforts. Its location on the Menominee River, along with its historic significance and high hazard potential, make Twin Falls a site of interest for water resource and climate enthusiasts looking to understand the intersection of human infrastructure and natural ecosystems.
