Summary
The lake, formed by an earth dam completed in 1977, has a maximum storage capacity of 360 acre-feet and a normal storage level of 57 acre-feet. With a surface area of 487 acres and a drainage area of 4 square miles, Eel Lake provides habitat for a variety of aquatic species and serves as a recreational spot for nature enthusiasts.
Despite its low hazard potential, Eel Lake has a moderate risk assessment due to its structural modifications in 1977. The dam has a height of 9 feet and a hydraulic height of 4 feet, with a spillway width of 50 feet. The lake's condition assessment is not rated, and it undergoes inspections every 10 years to ensure its safety and functionality. Managed by the Forest Service, Eel Lake is a vital water resource in the region, supporting the diverse ecosystem and providing opportunities for outdoor activities.
With its tranquil waters and abundant wildlife, Eel Lake is a haven for water resource and climate enthusiasts seeking to explore the beauty of Minnesota's natural landscapes. The lake's remote location, surrounded by the peaceful wilderness of the Itasca County, offers a serene escape for those looking to connect with nature and appreciate the importance of preserving our precious water resources. Whether you're fishing, birdwatching, or simply enjoying the scenic views, Eel Lake is a hidden gem waiting to be discovered and cherished for its ecological significance and recreational value.

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.
