Auroraville is a privately owned dam located in Waushara County, Wisconsin, along Willow Creek. Completed in 1987, this Gravity type dam stands at 13 feet tall and stretches 350 feet in length, with a storage capacity of 1320 acre-feet. The dam serves multiple purposes including recreation and water storage, with a surface area of 209 acres and a drainage area of 80 square miles. Despite its fair condition assessment, Auroraville poses a high hazard potential and is under state regulation and inspection by the Wisconsin Department of Natural Resources.

The dam's risk assessment is classified as very high, with a hazard potential of high due to its location and structural height. The dam has a controlled spillway type, although specific dimensions are not provided. The last inspection in September 2019 revealed a fair condition, and the dam is subject to regular inspections every two years. With its proximity to the Willow Creek and its importance for water regulation and recreation in the area, Auroraville is a key infrastructure for water resource and climate enthusiasts to monitor and maintain to ensure public safety and environmental sustainability.
