Summary
Built in 1959 by the Natural Resources Conservation Service, this earth dam stands at a height of 23 feet and has a storage capacity of 138 acre-feet. The dam primarily regulates the flow of the TR-MOREAU river, offering irrigation for agricultural purposes in the area.
Despite being categorized as having a low hazard potential and not yet rated for its condition assessment, Fox Irrigation Dam plays a vital role in water management within South Dakota. With a maximum discharge capacity of 840 cubic feet per second, this structure ensures controlled water release and storage, contributing to the overall sustainability of the local ecosystem. While lacking certain regulatory assessments and emergency preparedness measures, the dam continues to support the agricultural community in the region.
As a significant component of the water infrastructure in the area, Fox Irrigation Dam represents a key intersection of private ownership and public resource management. With its historical significance dating back to the late 1950s, this earth dam stands as a testament to the ongoing need for efficient water storage and distribution systems in the face of changing climate patterns. As water resource and climate enthusiasts explore the dynamics of this structure, its role in sustaining agricultural practices and environmental balance becomes increasingly apparent.

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.
