Grasshopper Hollow Tailings Dam dam
Grasshopper Hollow Tailings Dam
Grasshopper Hollow Tailings Dam, located in Berkeley Springs, West Virginia, was completed in 1965 and stands at a height of 129 feet, with a length of 720 feet. This rockfill dam serves the primary purpose of holding tailings, with a storage capacity of 1260 acre-feet. Situated near the Potomac River, this privately owned structure is under the regulatory oversight of the West Virginia Department of Environmental Protection.
Despite its satisfactory condition assessment as of November 2015, Grasshopper Hollow Tailings Dam is classified as having a high hazard potential. Regular inspections by state authorities ensure that the dam meets safety standards, with the last inspection taking place in November 2015. While an Emergency Action Plan (EAP) has not been prepared, the dam is monitored closely for any potential risks or threats to surrounding areas.
As a crucial component of water resource management in the region, Grasshopper Hollow Tailings Dam plays a vital role in controlling the flow of water and protecting the environment. With its strategic location and significant storage capacity, the dam serves as a key infrastructure for maintaining water quality and mitigating the impacts of climate change on the surrounding ecosystem.
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.
- 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.
Plan around the weather

About Grasshopper Hollow Tailings Dam
Where does the data for Grasshopper Hollow Tailings Dam 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.
