Summary
Completed in 1966, this dam has a height of 33 feet and a length of 288 feet, providing a storage capacity of 80 acre-feet. It is situated on Tr-Firesteel Creek and falls under the jurisdiction of the USDA NRCS. The dam's hazard potential is classified as low, with a moderate risk assessment score of 3.
Despite its relatively low hazard potential, Dwyer plays a crucial role in providing essential water resources for fire protection and livestock usage in the surrounding area. The dam's location within the St. Paul District highlights its significance in managing water resources and protecting against potential risks. With a history dating back to the 1960s, Dwyer continues to serve its intended purposes efficiently, contributing to the overall water management efforts in South Dakota.
As a part of the larger ecosystem, Dwyer stands as a testament to the collaborative efforts between private owners and federal agencies like the USDA NRCS in safeguarding water resources and mitigating potential hazards. Its strategic placement on Tr-Firesteel Creek ensures a reliable supply of water for various uses, highlighting the importance of such structures in maintaining a sustainable environment. With a focus on fire protection and supporting local agriculture, Dwyer exemplifies the intersection of water resource management and climate resilience in South Dakota.

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.
