Summary

This earth dam, with a height of 42 feet and a length of 242 feet, was completed in 1959 under the supervision of USDA NRCS. It is designed to store water and mitigate flooding in the surrounding area, offering protection to the local community and infrastructure. The dam has a normal storage capacity of 6 acre-feet and a maximum storage capacity of 97 acre-feet, serving as a crucial asset in managing water resources in the region.

Managed by the West Virginia Department of Environmental Protection (DWWM) and inspected regularly for safety and functionality, Upper Grave No.7 has been assessed as being in satisfactory condition, with a high hazard potential due to its proximity to residential and commercial areas. In case of emergency, the dam has an uncontrolled spillway for excess water discharge. The structure also meets state regulatory standards, ensuring its effectiveness in flood control and risk management. With a moderate risk assessment score of 3, efforts to enhance risk management measures and emergency response plans are continuously evaluated to safeguard the local community and environment.

Beyond its practical function, Upper Grave No.7 stands as a testament to the collaborative efforts of federal and state agencies in safeguarding water resources and managing climate-related risks. Through the coordination of the USDA NRCS and DWWM, this dam serves as a critical infrastructure piece in the region's water management system, contributing to the resilience of the community in the face of changing climate patterns. As a well-maintained and regulated structure, Upper Grave No.7 exemplifies the importance of proactive measures in ensuring water resource sustainability and climate adaptation for future generations.

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.
