Buffalo Lake Dam, also known as Montello Dam, is a gravity dam located in Marquette, Wisconsin, along the Fox River. Built in 1922, the dam stands at a height of 13 feet and has a length of 2800 feet. It serves multiple purposes, including flood control and water storage, with a maximum storage capacity of 19,000 acre-feet and a normal storage capacity of 10,000 acre-feet.

The dam is owned and regulated by the Wisconsin Department of Natural Resources (WIDNR), with state permitting, inspection, and enforcement in place to ensure its safety and functionality. Despite being rated as having a low hazard potential, the dam undergoes regular inspections every 10 years to assess its condition. In case of emergencies, an Emergency Action Plan (EAP) is in place, last revised in 2016, to guide response procedures and communicate with relevant stakeholders.

Buffalo Lake Dam plays a crucial role in managing water resources in the area, with a moderate risk assessment rating of 3. Its location in the beautiful city of Montello makes it a noteworthy structure for water resource and climate enthusiasts to explore and learn about the intersection of infrastructure, environmental stewardship, and public safety.
