Summary
Wilson is a privately owned dam located in Meade, South Dakota, along the TR CHEYENNE river. Completed in 1946, this earth dam stands at 15 feet tall and has a length of 1200 feet. With a storage capacity of 138 acre-feet, E.B. Wilson serves as a vital water resource for the surrounding area, with a maximum discharge capability of 8000 cubic feet per second.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), E.B. Wilson is subject to state regulations, permitting, inspection, and enforcement. Despite being rated as having a low hazard potential and not yet having a condition assessment, this dam plays a crucial role in water management and flood control in the region. With Dusty Johnson (R) as the representative for the area, the dam's maintenance and operation ensure the safety and sustainability of the water resources it protects.
While E.B. Wilson has not undergone recent inspections or assessments, its historical significance and role in water resource management highlight the importance of continued monitoring and maintenance. As a key infrastructure in the St. Paul District, this dam contributes to the overall water supply and climate resilience of the region. With a focus on environmental protection and risk management, E.B. Wilson represents a crucial piece of the puzzle in ensuring sustainable water resources for future generations.

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.
