Summary
With a structural height of 13 feet and a hydraulic height of 8 feet, this earth dam spans 90 feet in length and has a storage capacity of 3,790 acre-feet. The dam is situated in Marinette, Wisconsin, owned by a public utility, and falls under the jurisdiction of the Federal Energy Regulatory Commission.
This high-hazard potential dam has a risk assessment rating of 2, indicating a significant level of risk that must be carefully managed. The last inspection was conducted in June 2019, with a frequency of one inspection per year. Despite its age, the condition assessment for Big Quinnesec Falls Dike "B" is not available, highlighting the need for ongoing monitoring and maintenance to ensure its continued safety and functionality. Overall, this dam plays a crucial role in water resource management and energy production in the region, making it a key point of interest for water resource and climate enthusiasts.
In the event of an emergency, the dam's emergency action plan (EAP) preparation status and adherence to guidelines remain unclear, underscoring the importance of proactive risk management measures. With no spillway in place, it is essential to stay updated on the dam's condition and any modifications made over the years to mitigate potential risks. Big Quinnesec Falls Dike "B" serves as a reminder of the intricate balance between harnessing water resources for energy production and ensuring the safety and well-being of surrounding communities and ecosystems.

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.
