Summary

2, located in North Redwood, Minnesota, is a state-regulated earth dam built in 1979 for flood risk reduction along the Minnesota River. With a height of 7 feet and a length of 75 feet, this dam provides a storage capacity of 420 acre-feet to help manage water flow in the region. The dam is classified as having a low hazard potential and is currently in satisfactory condition based on a 2017 assessment.

Managed by the Minnesota Department of Natural Resources, Dike No. 2 plays a crucial role in reducing flood risks and protecting the surrounding areas from potential water damage. The dam is regularly inspected, with the last assessment conducted in March 2017, and meets state permitting, inspection, and enforcement requirements. With its strategic location and design, Dike No. 2 is a key component in the overall water resource management efforts in Redwood County, Minnesota.

For water resource and climate enthusiasts, Dike No. 2 serves as a notable example of infrastructure designed to mitigate flood risks and enhance water management in a state-regulated setting. As part of the larger network of flood control measures along the Minnesota River, this earth dam underscores the importance of proactive planning and maintenance to safeguard communities and natural resources from the impacts of extreme weather events and changing climate conditions.

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.
