Summary
The dam, situated on the TR Moreau River, is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections to ensure its safety and compliance with state regulations.
With a maximum discharge capacity of 4,200 cubic feet per second, Lloyd Fox Dam No.2 plays a crucial role in managing water resources in the area and reducing the risk of floods. Despite being classified as having a low hazard potential, the dam's condition assessment is currently not rated, underscoring the importance of ongoing monitoring and maintenance to ensure its integrity and effectiveness in safeguarding the surrounding community and environment.
As a key infrastructure designed and managed by the Natural Resources Conservation Service, Lloyd Fox Dam No.2 highlights the critical role of earth dams in water resource management and climate resilience efforts. Its presence on the TR Moreau River not only contributes to flood control and water storage but also underscores the need for proactive risk management and emergency preparedness to mitigate potential threats and ensure the safety and sustainability of the dam and its surrounding area.

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.
