Summary

With a height of 4.5 meters and a core type of buttress earth dam, it provides a storage capacity of 60 acre-feet, covering a surface area of 1 acre and draining an area of 2.2 square kilometers. The dam is designed to control the flow of water and minimize the risk of flooding in the region.

Managed by private owners, Lundquist Dam is regulated by the Minnesota Department of Natural Resources and is subject to regular inspections to ensure its structural integrity. Despite being categorized with a low hazard potential, the dam's condition was assessed as satisfactory during the last inspection in October 2012. With an uncontrolled spillway and outlet gates, the dam is equipped to handle moderate risk situations, emphasizing the importance of proper risk management measures in maintaining the safety and functionality of the structure.

For water resource and climate enthusiasts, Lundquist Dam represents a significant infrastructure project that plays a crucial role in protecting the surrounding community from potential flood risks. With its strategic location and design features, the dam serves as a key component in the overall water management system of the area, highlighting the importance of proactive measures in safeguarding against natural disasters and ensuring the sustainable use of water resources in the region.

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.
