Summary
3, located in Masontown, West Virginia, is a state-regulated earth dam designed by the USDA NRCS for flood risk reduction along the Upper Deckers river. Completed in 1968, this dam stands at a height of 13.8 feet and has a storage capacity of 78.3 acre-feet, with a normal storage level of 15.3 acre-feet. The dam has a low hazard potential and is currently in fair condition, last inspected in May 2016.
Although the dam has uncontrolled spillways and outlet gates, its risk assessment is moderate, indicating a need for continued monitoring and potential risk management measures. The dam is under the regulatory oversight of the West Virginia Department of Environmental Protection's Division of Water and Waste Management, ensuring that it is inspected, permitted, and enforced in accordance with state regulations. With its strategic location and purposeful design, Upper Deckers No. 3 serves as a key component in mitigating flood risks in the region, highlighting the importance of sustainable water resource management in the face of changing climate patterns.

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.
