Summary
Constructed in 1969 by the USDA NRCS, this earth dam stands at a height of 34 feet and has a storage capacity of 328 acre-feet. With a drainage area of 1.21 square miles, this dam plays a vital role in protecting the surrounding area from potential flooding events.
Managed by the West Virginia Department of Environmental Protection, Patterson Creek No.44 is regularly inspected and maintained to ensure its structural integrity. The dam has been assessed as being in satisfactory condition, with a high hazard potential due to its location and the volume of water it can hold. While the risk level is considered moderate, the authorities are prepared with emergency action plans to mitigate any potential threats and protect the community in case of a flood.
With its primary purpose being flood risk reduction, Patterson Creek No.44 serves as a critical infrastructure for water resource management in Mineral County. As part of the Pittsburgh District, the dam is a testament to the collaborative efforts between local government and federal agencies to safeguard the region from the impacts of extreme weather events. As climate change continues to pose challenges to water resources, structures like Patterson Creek No.44 play a vital role in ensuring the resilience of communities against the threat of flooding.

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.
