Amherst, a private-owned dam located in Portage County, Wisconsin, serves primarily for recreation purposes on the Waupaca River. The dam, with a height of 14 feet and a length of 370 feet, was completed in 1857 and has a storage capacity of 260 acre-feet. It has a significant hazard potential and is classified as having a very high risk level.

The dam is regulated by the Wisconsin Department of Natural Resources (WIDNR) and undergoes regular inspections, with the last assessment conducted in July 2013. Despite being in fair condition, Amherst is considered to be at significant risk due to its age and potential safety hazards. The dam has experienced modifications in 1883 and 2016, indicating ongoing efforts to ensure its safety and compliance with regulations.

As a popular spot for recreational activities, Amherst Dam plays a vital role in providing opportunities for outdoor enthusiasts to enjoy the natural beauty of the surrounding area. However, with its age and risk level, continued monitoring and maintenance are essential to ensure the safety of both the dam and the community it serves.
