Summary
Sitting on Halls Run, this dam stands at a height of 25 feet and has a storage capacity of 323 acre-feet. The dam covers a surface area of 31 acres and serves as a significant hazard potential with a satisfactory condition assessment.
Managed by a private owner, Lake Floyd Dam is regulated by the West Virginia Department of Environmental Protection (DWWM) and undergoes regular inspections to ensure its safety. With a state jurisdiction and permitting in place, the dam is considered a vital resource for recreational activities in the area. Despite its age, the dam continues to provide storage and flood protection for the surrounding community.
With a risk assessment and emergency action plan in place, Lake Floyd Dam remains a crucial water resource for the region. Its structural integrity and maintenance are closely monitored to mitigate potential risks and ensure the safety of nearby residents. As a popular spot for outdoor enthusiasts, this dam plays a key role in water management and climate resilience efforts in West Virginia.

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.
