Summary
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.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
