Mcdill, a local government-owned dam located in Portage, Wisconsin, serves as a vital structure on the Plover River. Built in 1855, this Earth-type dam stands at a height of 20.6 feet and has a significant hazard potential. With a storage capacity of 2160 acre-feet and a drainage area of 163 square miles, Mcdill plays a crucial role in regulating water flow and providing flood control measures for the surrounding area.

Despite its age, Mcdill has undergone modifications in 1962 and 2000 to enhance its efficiency and safety. Regular inspections are conducted, with the most recent one in September 2019, revealing a satisfactory condition assessment. The dam is regulated by the Wisconsin Department of Natural Resources (WIDNR) and meets state permitting, inspection, and enforcement requirements. In case of emergencies, however, there is no detailed Emergency Action Plan (EAP) in place, raising concerns about the dam's preparedness for unforeseen events.

Overall, Mcdill presents a blend of historical significance and practical utility in managing water resources in the region. Its location on the Plover River, along with its storage capacity and hazard potential, underscores the importance of continued monitoring and maintenance to ensure the safety and efficiency of this essential water infrastructure.
