Summary

The primary purpose of this structure is flood risk reduction along the Minnesota River. With a dam height of 31 feet and a length of 304 feet, the pond has a storage capacity of 15.4 acre-feet and serves as a vital resource in managing water levels and mitigating potential flood damage in the area.

Managed by the MNDNR EWR, Halverson Farm Pond is regulated, inspected, and enforced by the state of Minnesota to ensure its structural integrity and functionality. The dam is classified as having low hazard potential and fair condition assessment, making it a relatively stable and safe infrastructure. The location of the pond along the Minnesota River-TR provides essential flood control measures for the region, contributing to both water resource management and climate resilience efforts in the area.

Overall, Halverson Farm Pond plays a crucial role in flood risk reduction and water management in Yellow Medicine County. As a part of the larger network of water infrastructure in the region, this earth dam serves as a key tool in protecting communities and ecosystems from the impacts of extreme weather events and climate change. Supported by the USDA NRCS and state regulators, the pond exemplifies the collaboration and innovation needed to address water resource challenges in a changing climate.

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.
