Summary
Built in 1975 by the Natural Resources Conservation Service, this Earth-type dam stands at a height of 20 feet and has a structural height of 22 feet, with a total length of 435 feet. The pond serves a primary purpose of flood risk reduction for the surrounding area, with a storage capacity of 31.6 acre-feet and a normal storage level of 15 feet.
Managed by the MNDNR EWR, the Miller Estate Farm Pond is regulated, permitted, inspected, and enforced by the state of Minnesota. With a significant hazard potential and a satisfactory condition assessment as of November 2012, the pond is subject to regular inspections every four years to ensure its safety and functionality. Despite its uncontrolled spillway and outlet gates, the pond has a moderate risk assessment level of 3, indicating a manageable level of risk.
Overall, the Miller Estate Farm Pond plays a crucial role in mitigating flood risks in the area along the YELLOW MEDICINE RIVER-TR. As a privately owned water resource under state jurisdiction, it stands as a testament to successful collaboration between private landowners and government agencies in managing and maintaining essential water infrastructure for the community.

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.
