Summary
Situated in the city of Springvale, this water resource is part of the Stanchfield Creek watershed and is managed by the Minnesota Department of Natural Resources. With a storage capacity of 100 acre-feet and a drainage area of 6.9 square miles, this earth dam structure serves as a critical habitat for local wildlife and contributes to the conservation efforts in the region.
Although the primary purpose of Cranberry WMA South Pool is for fish and wildlife management, the dam also plays a role in flood control and water quality improvement. The dam's spillway is designed as a controlled structure to manage water levels effectively, with a low hazard potential due to its current condition assessment being rated as poor. Despite the risk assessment indicating a very high risk level, the dam's emergency action plan status and risk management measures are currently unlisted, highlighting the need for continued monitoring and maintenance to ensure the safety and functionality of this important water resource.
As a key feature of the local ecosystem, Cranberry WMA South Pool provides valuable habitat for a variety of plant and animal species. With its strategic location within the Stanchfield Creek watershed, this dam serves as a crucial component of the region's water management infrastructure. As water resource and climate enthusiasts, it is essential to recognize the significance of maintaining and protecting such vital ecosystems to ensure a sustainable future for both wildlife and human communities that depend on these resources.

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.
