Summary
7 is a state-owned dam located in Preston, West Virginia, along Deckers Creek. Designed by the USDA NRCS and completed in 1968, this earth dam stands at a height of 14.9 feet and serves primarily for flood risk reduction. With a storage capacity of 97.8 acre-feet, this dam has a spillway type of "Uncontrolled" and a hazard potential rated as "High."
Despite its age, Upper Deckers No. 7 is in fair condition as of the last assessment in May 2016. The dam is regulated by the West Virginia Department of Environmental Protection (DWWM) and undergoes regular inspections, with the last one conducted in 2016. While it meets state permitting and enforcement requirements, there is a moderate risk associated with the dam, rated at level 3.
With its crucial role in flood risk reduction along Deckers Creek, Upper Deckers No. 7 remains a vital structure in the region's water resource management efforts. Enthusiasts of water resources and climate change will appreciate the significance of this dam in protecting the surrounding area from potential flooding events and the ongoing efforts to ensure its safety and effectiveness.

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.
