Summary
Completed in 1954, this dam serves as a crucial structure in managing the water resources of the area, particularly in regulating the flow of the tributary Bad River. The dam has a storage capacity of 24 acre-feet and a maximum discharge of 315 cubic feet per second, making it a significant asset for water management in the region.
Despite being classified as having a low hazard potential, Boyd #1 is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, enforcement, and permitting processes. The dam's condition is currently listed as "Not Rated," indicating the need for further assessment. While emergency action plans and risk assessments for the dam are not currently available, the structure's importance in water resource management underscores the necessity for proactive measures to ensure its continued safety and functionality in the face of changing climate conditions.
Overall, Boyd #1 represents a vital component of water resource infrastructure in South Dakota, serving as a key element in the regulation of the Bad River tributary. As climate change continues to impact water resources, the proper maintenance and monitoring of dams like Boyd #1 become increasingly essential to ensure the safety and sustainability of water supplies for both human and environmental needs. With its history of service since 1954, Boyd #1 stands as a testament to the importance of responsible water resource management in the face of a changing climate landscape.

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.
