Summary

This dam primarily serves the purpose of flood risk reduction along the Rock River, with a height of 21 feet and a length of 2700 feet. It has a storage capacity of 149 acre-feet and a surface area of 10 acres, providing essential protection to the surrounding area.

Managed by the Minnesota Department of Natural Resources, Luverne North is regulated, permitted, inspected, and enforced to ensure its structural integrity and safety. With a low hazard potential and satisfactory condition assessment as of 2015, the dam is equipped with a spillway width of 200 feet to handle a maximum discharge of 250 cubic feet per second. Its location in S3 T102N R45W makes it a vital component in the flood management infrastructure of the region.

Luverne North plays a crucial role in mitigating flood risks in the area, with its effective design and construction meeting regulatory standards. As a key flood risk reduction structure along the Rock River, this dam contributes to the overall water resource management efforts in Minnesota, safeguarding the community of Luverne and its surroundings from potential flooding events.

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.
