Legend Lake Number Three, located in Menominee, Wisconsin, is a privately owned dam constructed in 1971 primarily for recreational purposes. This gravity-type dam, standing at 22 feet tall with a hydraulic height of 15 feet, spans a length of 1200 feet and has a storage capacity of 20,000 acre-feet. The reservoir covers a surface area of 1304 acres and is fed by Linzy Creek, with a drainage area of 21.8 square miles.

Despite its satisfactory condition assessment as of October 2020, Legend Lake Number Three has a high hazard potential, with a very high risk assessment rating. The dam is regulated by the Wisconsin Department of Natural Resources, which conducts regular inspections and enforces safety measures. The last inspection was carried out in July 2019, with a frequency of every two years. In the event of an emergency, the dam's emergency action plan is in place, although its last revision dates back to 2014.

Water resource and climate enthusiasts will be intrigued by the engineering and environmental aspects of Legend Lake Number Three. Its controlled spillway, high hazard potential, and risk assessment rating provide insight into the complex management and regulation of water resources in Wisconsin. The dam's location within a recreational area adds an additional layer of significance, highlighting the intersection between human recreation and the natural environment.
