Summary

The dam stands at a height of 8 feet and stretches 53 feet in length, containing a maximum storage capacity of 6,842 acre-feet. With a normal storage capacity of 5,909 acre-feet, Eagle Lake serves as a vital water source for the surrounding area, covering a surface area of 358 acres and draining a watershed of 123 acres through Daggett Brook.

Managed by the Minnesota Department of Natural Resources, Eagle Lake's dam is regularly inspected and maintained to ensure its structural integrity and safe operation. Despite being classified as having a low hazard potential, the dam is equipped with satisfactory safety measures and emergency protocols. The surrounding area benefits from the lake's regulated water flow, with the dam playing a crucial role in flood control and water supply management, ultimately contributing to the ecological health and sustainability of the region.

Eagle Lake's historical significance as a Works Progress Administration project and its ongoing role in water management make it a noteworthy site for water resource and climate enthusiasts. With its picturesque setting and functional design, the dam at Eagle Lake stands as a testament to the importance of responsible water infrastructure in sustaining both natural ecosystems and human communities in Minnesota.

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.
