Summary
Completed in 1935, this dam boasts a height of 11 feet and a storage capacity of 270 acre-feet, serving a drainage area of 68 square miles. With a normal storage capacity of 230 acre-feet and a surface area of 38 acres, Beaver Creek 3 plays a crucial role in water management in the region.
Despite its significance, Beaver Creek 3 is currently in an unsatisfactory condition, highlighting the need for regular inspections and maintenance. The last inspection in 2013 found the dam to have a low hazard potential, but with a very high risk assessment rating. The regulatory oversight by the Wisconsin Department of Natural Resources ensures that the dam meets safety standards and operates effectively. However, the structure's risk management measures and emergency preparedness require further attention to mitigate potential risks and ensure the safety of downstream communities.
With its controlled spillway and historic significance, Beaver Creek 3 stands as a testament to the intersection of water resource management and climate resilience. As water enthusiasts and climate advocates, it is imperative to monitor and support the maintenance and operation of such critical infrastructure to safeguard water resources and mitigate risks posed by climate variability and extreme weather events. The collaboration between state and federal agencies, along with community engagement, is essential in ensuring the longevity and safety of Beaver Creek 3 for generations to come.

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.
