Summary
Completed in 2006, these earth dams have a height of 8 feet and a storage capacity of 1107 acre-feet, with a surface area of 415 acres. Despite their low hazard potential, the condition of these dikes has not been rated, and they have not undergone recent inspections.
These dikes play a crucial role in enhancing the local ecosystem by providing habitat for various fish and wildlife species. However, the lack of recent assessments and maintenance raises concerns about their long-term sustainability and effectiveness. With their location in a flood-prone area along the Minnesota River, it is essential to prioritize regular inspections, maintenance, and risk management measures to ensure the continued functionality and safety of Mn River Pool 7 Dikes 1 & 2.
As water resource and climate enthusiasts, it is important to recognize the significance of these dikes in supporting biodiversity and ecosystem health in the region. By staying informed about their condition, advocating for proper management practices, and promoting sustainable water resource policies, we can contribute to the preservation of these vital habitat structures and the overall resilience of the Minnesota River ecosystem.

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.
