Summary
Managed by the Minnesota Department of Natural Resources, this site is part of the Stanchfield Creek watershed and was completed in 1992. The dam at this location is of the buttress type, with a height of 11 feet and a length of 1000 feet, creating a reservoir with a storage capacity of 113 acre-feet.
With a surface area of 22 acres and a drainage area of 4 square miles, Cranberry WMA North Pool serves as a vital habitat for wildlife and contributes to the overall ecosystem health in the region. It is designed with a controlled spillway and has a low hazard potential, with a risk assessment rating of very high. While the dam's condition assessment is not rated, regular inspections are conducted, with the last inspection taking place in August 2019.
Enthusiasts interested in water resources and climate in the area can appreciate the importance of Cranberry WMA North Pool as a regulated and permitted water infrastructure that plays a crucial role in water management and conservation efforts in Minnesota. Its location within the Stanchfield Creek watershed and its significant storage capacity make it a key component of the region's water resource infrastructure, contributing to flood control, wildlife habitat, and recreational opportunities for visitors.

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.
