Summary
The dam stands at a height of 22 feet, with a hydraulic height of 67 feet, making it a significant structure in the area. With a normal storage capacity of 3000 acre-feet and a maximum discharge of 33,000 cubic feet per second, the dam plays a crucial role in water resource management and energy generation in the region.
The dam features a gravity design with a multi-arch core and rock foundation, adding to its structural integrity. Equipped with needle and tainter (radial) outlet gates, the dam has a controlled spillway with a width of 51 feet. Despite its high hazard potential, the dam has not been assessed for its condition, but regular inspections by the Federal Energy Regulatory Commission ensure its safety and compliance with regulatory standards. Little Quinnesec Falls serves as a key example of sustainable hydroelectric infrastructure that balances the need for clean energy production with environmental conservation.
Water resource and climate enthusiasts will find Little Quinnesec Falls to be a fascinating site that showcases the intersection of infrastructure development, energy generation, and environmental stewardship. As a federally regulated dam under the jurisdiction of the Federal Energy Regulatory Commission, the dam represents a model of responsible resource management. Its location on the Menominee River adds to its significance, providing a vital source of water and power to the surrounding community. The dam's historical legacy, combined with its modern operational features, makes it a compelling subject for those interested in the dynamics of water resources and climate resilience.

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.
