Summary
1, located in North Redwood, Minnesota, along the Minnesota River, is a state-regulated structure built in 1979 for the primary purpose of flood risk reduction. This earth-type dam stands at a height of 8 feet with a structural height of 10 feet and a length of 520 feet. With a storage capacity of 420 acre-feet, Dike No. 1 plays a crucial role in managing water levels in the area, covering a drainage area of 4.7 square miles.
Managed by the Minnesota Department of Natural Resources, Dike No. 1 has been deemed to have a low hazard potential and is assessed to be in satisfactory condition as of the last inspection in 2017. With state permitting, inspection, and enforcement in place, this vital infrastructure ensures the protection of surrounding communities from potential flooding events. As a part of the overall flood risk reduction strategy, Dike No. 1 contributes to the resilience and safety of the area, serving as a key component of water resource management in Redwood County, Minnesota.
Collaboration between state agencies and local authorities is essential for the continued maintenance and operation of Dike No. 1. As a vital piece of infrastructure along the Minnesota River, this structure showcases the importance of proactive measures in mitigating flood risks and ensuring the long-term sustainability of water resources in the region. With its strategic location and purposeful design, Dike No. 1 stands as a testament to effective water management practices in the face of changing climate conditions and increasing water-related challenges.

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.
