Summary

Built in 1949, this earth dam stands at a height of 10 feet and spans 100 feet in length, with a storage capacity of 3,790 acre-feet and a drainage area of 2,475 acres. Managed by the Federal Energy Regulatory Commission, this structure plays a crucial role in water resource management in the region.

Despite its age, Big Quinnesec Falls Dike "A" continues to be a significant asset, with a high hazard potential due to its condition assessment not being available. The dam has a maximum discharge capacity of 39,347 cubic feet per second, highlighting its importance in flood control efforts along the Menominee River. While there have been no recent modifications or inspections, the dam remains a focal point for risk management measures, with an Emergency Action Plan last revised in 1999.

With its picturesque location and essential role in water resource management, Big Quinnesec Falls Dike "A" stands as a testament to the intersection of environmental conservation and infrastructure development. As climate change continues to impact water resources, structures like this provide a glimpse into the importance of sustainable practices and effective risk management in safeguarding our waterways for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
