Summary

Constructed in 1958 by the USDA NRCS, this dam stands at a height of 48 feet and has a hydraulic height of 46 feet. With a storage capacity of 44 acre-feet and a drainage area of 0.15 square miles, this dam plays a vital role in mitigating potential flooding in the area.

Managed by the local government and regulated by the West Virginia Department of Environmental Protection, Upper Grave No.3 has a high hazard potential but is currently in satisfactory condition. The dam, with an uncontrolled spillway and outlet gates, underwent its last inspection in April 2014. Despite its moderate risk assessment, the dam meets regulatory guidelines and is equipped to handle emergency situations effectively.

With its primary purpose being flood risk reduction, Upper Grave No.3 serves as a critical infrastructure to protect the surrounding community from potential disasters. As water resource and climate enthusiasts, understanding the significance of this dam in maintaining the safety and well-being of the region is essential in appreciating the vital role it plays in water management and environmental conservation efforts.

Dam Data Reference

Condition Assessment

Satisfactory
No 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

High
Dams 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.
