Summary
Built in 1958 by the Natural Resources Conservation Service, this earth dam on the TR Moreau River serves as a vital water storage solution in the region. With a height of 13 feet and a storage capacity of 94 acre-feet, the dam plays a crucial role in managing water resources in the area.
Despite its low hazard potential and unassessed condition, Wilson Ranch Dam remains under the regulatory oversight of the South Dakota Department of Agriculture and Natural Resources. With state permitting, inspection, and enforcement processes in place, the dam is subject to regular monitoring to ensure its safety and functionality. While last inspected in 1985, the dam's emergency action plan and risk management measures are yet to be fully assessed, highlighting the need for ongoing vigilance in the face of changing climate conditions.
As climate change continues to impact water resources across the globe, Wilson Ranch Dam stands as a symbol of resilience and adaptability in the face of environmental challenges. With its strategic location on the TR Moreau River and its role in water storage and management, the dam serves as a critical piece of infrastructure for the local community. As efforts to address climate-related risks and strengthen emergency preparedness intensify, Wilson Ranch Dam remains a key player in safeguarding water resources for future generations.

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.
