Summary
Butler No.2 is a privately owned earth dam located in Ziebach, South Dakota, along the TR MOREAU river. Constructed in 1954 by the Natural Resources Conservation Service, this dam stands at 14 feet in height and has a storage capacity of 102 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," B. Butler No.2 plays a crucial role in water resource management in the area.
Managed by the South Dakota Department of Environment and Natural Resources, this dam is regulated, permitted, inspected, and enforced to ensure its safe operation. While the dam has not been rated for its condition, it continues to serve its primary purpose effectively. With Dusty Johnson (R) as the representative in Congress for the area, stakeholders and enthusiasts in water resource and climate management can be assured of the dam's continued role in flood control and water supply.
Despite lacking a detailed risk assessment or emergency action plan, B. Butler No.2 remains a key infrastructure in the region, providing essential water management services. As climate change impacts water resources, the importance of maintaining and upgrading dams like B. Butler No.2 becomes increasingly vital in ensuring sustainable and resilient water management practices for the future.

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.
