Summary

Louis County. With a dam completed in 1922, this body of water boasts a surface area of 4800 acres and a maximum storage capacity of 46,900 acre-feet. The hydroelectric facility is regulated by the Federal Energy Regulatory Commission and is state-permitted, inspected, and enforced by the Minnesota Department of Natural Resources.

The dam, standing at a height of 39 feet and a structural height of 40 feet, spans a length of 1365 feet and is primarily made of concrete and earth materials. Whiteface Lake offers various recreational opportunities for enthusiasts and visitors, with the Skunk River and Whiteface River flowing nearby. The facility is equipped with two slide (sluice gate) outlet gates and has a low hazard potential, with a very high risk assessment rating.

The breathtaking Whiteface Lake not only serves as a source of clean, renewable hydroelectric power but also provides a tranquil setting for outdoor activities and water sports. Its rich history and engineering marvel make it a must-visit destination for water resource and climate enthusiasts looking to explore the intersection of human ingenuity and environmental sustainability.

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.
