Old Keyser Reservoir dam
Old Keyser Reservoir
Old Keyser Reservoir, also known as Old Limestone Dam, is a concrete dam located in Mineral County, West Virginia. Built in 1911, this local government-owned structure serves as a water supply source in the area, specifically for the city of WATER SUPPLY. Situated on LIMESTONE RUN, the reservoir has a height of 25 feet and can hold up to 62 acre-feet of water, with a normal storage capacity of 44 acre-feet.
With a hazard potential rated as high and a fair condition assessment as of 2014, Old Keyser Reservoir plays a crucial role in the region's water resource management. The dam has a length of 332 feet and a maximum storage capacity of 62 acre-feet, covering a surface area of 5 acres. Despite not being regulated by the state, the reservoir undergoes inspections every 2 years to ensure its structural integrity and safety for the surrounding community.
Old Keyser Reservoir stands as a historic water infrastructure that continues to provide vital water resources to the residents of Mineral County. With a solid concrete construction and a long-standing presence in the area, this reservoir represents a key component in the local water supply system. As climate change impacts water resources, the maintenance and management of structures like Old Keyser Reservoir become increasingly important to ensure sustainable access to clean water for the community.
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.

About Old Keyser Reservoir
Where does the data for Old Keyser Reservoir 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.
