Summary
Built in 1966 by the USDA NRCS, this earth dam stands at a height of 31 feet and has a hydraulic height of 29 feet, serving the primary purpose of flood risk reduction along the Patterson Creek. With a storage capacity of 168 acre-feet and a drainage area of 0.69 square miles, this dam plays a crucial role in managing water flow and mitigating potential flooding events in the region.
Managed by the West Virginia Department of Environmental Protection (DWWM), Patterson Creek No.47 is classified as having a significant hazard potential and a fair condition assessment as of the last inspection date in April 2014. Although the dam has experienced modifications over the years, it currently operates with uncontrolled spillways and outlet gates. While the risk assessment indicates a moderate level of risk, the structure is deemed to meet regulatory guidelines and is subject to regular inspections to ensure its continued safety and effectiveness in flood control efforts. Water resource and climate enthusiasts can appreciate the importance of this dam in protecting the local community from potential flooding disasters and in managing the flow of water along Patterson Creek.

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.
