Summary

This Earth-type dam stands at a height of 10 feet and stretches 140 feet in length, providing a maximum storage capacity of 437 acre-feet and a surface area of 70 acres. The lake is situated in a tranquil setting, surrounded by natural beauty and wildlife, making it a popular destination for water resource and climate enthusiasts.

Despite its low hazard potential and moderate risk assessment, Dutchman Lake has not been officially rated for its condition assessment. While it does not fall under state regulation or jurisdiction, the lake serves as an essential habitat for local fish and wildlife populations. The uncontrolled spillway and outlet gates add to the lake's charm, allowing for natural water flow and contributing to the overall ecosystem health. With a drainage area of 1.07 square miles and a peaceful setting in Grand Portage, Dutchman Lake offers a serene escape for those seeking to connect with nature and enjoy the beauty of Minnesota's landscapes.

Managed by the local government and the Natural Resources Conservation Service, Dutchman Lake remains a hidden gem for outdoor enthusiasts looking to explore the untamed wilderness of the St. Paul District. With its peaceful surroundings, diverse wildlife, and ample recreational opportunities, Dutchman Lake is a haven for those who appreciate the importance of preserving and protecting our precious water resources. Whether for fishing, wildlife observation, or simply enjoying the tranquility of the outdoors, Dutchman Lake offers a unique and enriching experience for all who visit.

Dam Data Reference

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.
