Summary

2, located in Red Wing, Minnesota, is a privately owned earth dam designed by the USDA NRCS for flood risk reduction in the Hay Creek-TR watershed. Completed in 1969, this structure stands at a height of 36 feet and has a length of 500 feet, providing storage capacity of 65 acre-feet. The dam is regulated by the Minnesota Department of Natural Resources and has a low hazard potential with a fair condition assessment.

Despite its relatively low hazard potential, Voth Detention No. 2 plays a crucial role in mitigating flood risks in the area, with a maximum discharge capacity of 1100 cubic feet per second. This structure, managed by private owners, is subject to state permitting, inspection, and enforcement to ensure its continued effectiveness in protecting the surrounding communities from potential flood events. With a moderate risk assessment score of 3, ongoing risk management measures are essential to maintain the dam's functionality and resilience in the face of changing climate conditions.

As water resource and climate enthusiasts, understanding the significance of structures like Voth Detention No. 2 in managing water flow and reducing flood risks is vital. With a focus on flood risk reduction and a collaborative approach between private owners, regulatory agencies, and designers, this earth dam serves as a critical component of the local watershed's infrastructure. Monitoring its condition, conducting regular inspections, and implementing risk management strategies are essential to ensure the long-term sustainability and effectiveness of Voth Detention No. 2 in safeguarding the community and the environment from potential water-related hazards.

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.
