Summary
Built in 1950, this earth dam stands at 1418 feet in length and has a storage capacity of 180 acre-feet. It is regulated by the South Dakota Department of Environment and Natural Resources, with permitting, inspection, and enforcement all conducted by state authorities.
Managed by the Natural Resources Conservation Service, Floyd Strong serves as a crucial structure for water resource management in the area, with a maximum discharge capacity of 2800 cubic feet per second. Despite its age, the dam's condition assessment is currently rated as "Not Rated," indicating a need for further evaluation to ensure its continued safety and functionality. Additionally, the dam has not been assigned a Dam Safety Action Classification (DSAC) date, suggesting a potential need for risk assessment and management measures in the future.
Overall, Floyd Strong plays a vital role in the local water infrastructure of Meade County, providing essential storage and flood control benefits. As a privately owned dam, it demonstrates the importance of state regulation and oversight in ensuring the safety and effectiveness of such structures. With its historical significance and ongoing operational needs, Floyd Strong represents a key asset for water resource and climate enthusiasts to monitor and support in the South Dakota region.

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.
