Upper Grave No.1 dam
Upper Grave No.1
Upper Grave No.1 is a rockfill dam located in Cameron, West Virginia, designed by the USDA NRCS and completed in 1959 for flood risk reduction along Grave Creek. With a height of 68 feet and a hydraulic height of 66 feet, this dam serves the primary purpose of flood risk reduction and has a storage capacity of 284 acre-feet. Despite its satisfactory condition assessment in 2014, Upper Grave No.1 has a high hazard potential, highlighting the importance of regular inspections and maintenance to ensure its safety and effectiveness in managing flood risks in the region.
Owned by the local government and regulated by the West Virginia Department of Environmental Protection, Upper Grave No.1 is situated in Marshall County and falls under the jurisdiction of the DWWM. Although it has uncontrolled spillways and outlet gates, the dam has a normal storage capacity of 100 acre-feet and covers a surface area of 9 acres. The dam's risk assessment is moderate, emphasizing the need for continuous monitoring and risk management measures to address any potential vulnerabilities and ensure the safety of the surrounding community from flood events.
Overall, Upper Grave No.1 plays a crucial role in flood risk reduction efforts in the region, with its strategic location along Grave Creek and its capacity to store water during periods of high discharge. As a key infrastructure asset, the dam requires ongoing attention and adherence to regulatory guidelines to mitigate hazards and protect the community from the impacts of flooding. By staying vigilant and proactive in its maintenance and management, Upper Grave No.1 can continue to fulfill its vital role in safeguarding the area from flood risks and ensuring the resilience of water resources in the region.

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.
- 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.
- 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.
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, environmental 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.

About Upper Grave No.1
Where does the data for Upper Grave No.1 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
