Summary
Owned by the local government, the dam stands at a height of 26 feet and spans 750 feet in length, with a storage capacity of 195 acre-feet. The dam's hazard potential is rated as low, with a fair condition assessment as of May 2018.
Managed by the Minnesota Department of Natural Resources - Division of Ecological and Water Resources, Duncan Avenue dam is regulated, permitted, inspected, and enforced by the state. The structure plays a crucial role in mitigating flood risks in the Redwood County area, with a drainage area of 1.75 square miles. Despite its low hazard potential, regular inspections are conducted every 8 years to ensure the dam's structural integrity and functionality.
For water resource and climate enthusiasts, Duncan Avenue serves as a vital infrastructure for flood control in Minnesota, safeguarding the local community from potential inundation events. With its rockfill construction and buttress core type, the dam represents a crucial component of the state's flood risk reduction strategy. As climate change continues to impact precipitation patterns and water levels, the maintenance and monitoring of structures like Duncan Avenue become increasingly important in ensuring the resilience of water resource systems.

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.
