Summary
Completed in 1965, this earth dam stands at a height of 85 feet and serves primarily for flood risk reduction. With a maximum storage capacity of 5,799 acre-feet and a normal storage of 149 acre-feet, it covers a surface area of 25 acres and drains an area of 17.81 square miles.
Located in Burlington, Mineral County, this dam on Mike's Run is regulated by the West Virginia Department of Environmental Protection and is subject to state permitting, inspection, and enforcement. The dam's spillway is uncontrolled, and its hazard potential is rated as high. Despite being in moderate risk, the condition of the dam is not rated, highlighting the importance of ongoing monitoring and maintenance to ensure public safety in the event of an emergency.
While the dam has not been modified in recent years and lacks a formal Emergency Action Plan (EAP), its risk management measures and inundation maps remain underdeveloped. With a designated inspection frequency of every two years, stakeholders must work towards enhancing the dam's safety protocols and preparedness to mitigate potential risks and safeguard the surrounding community and environment.

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.
