Summary
With a gravity dam type and a height of 9 feet, the dam provides a storage capacity of 130 acre-feet and serves multiple purposes including irrigation, recreation, and water supply. Despite its low hazard potential, the dam's condition assessment in 2013 was deemed unsatisfactory, highlighting the need for regular inspections and maintenance to ensure its safety and functionality.
Located within Congressional District 07 of Wisconsin, Beaver Creek 2 has a maximum discharge capacity of 1400 cubic feet per second and a controlled spillway type. The dam's surface area covers 14 acres with a drainage area of 5 square miles. Its risk assessment is characterized as very high, emphasizing the importance of implementing effective risk management measures to mitigate potential dangers and ensure the safety of surrounding communities. While the dam's emergency action plan status and inundation maps remain undisclosed, the dam's risk profile underscores the critical need for proactive monitoring and preparedness.
With an outdated last inspection date in 2013, Beaver Creek 2's risk management and emergency response protocols may not be up to date. It is imperative for state regulatory agencies such as WIDNR to conduct more frequent inspections and assessments to address the unsatisfactory condition of the dam and mitigate the very high risk associated with its operation. Enhancing the dam's maintenance and monitoring protocols can help safeguard the surrounding area from potential hazards and ensure the sustainability of Beaver Creek 2 for future generations.

Dam Data Reference
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.
