Cobbs Creek Regional Water Supply Reservoir Dam Perimeter Dam (Dam C) dam
Cobbs Creek Regional Water Supply Reservoir Dam Perimeter Dam (Dam C)
Located in Cumberland, Virginia, the Cobbs Creek Regional Water Supply Reservoir Dam Perimeter Dam (Dam C) is a critical structure designated for water supply purposes. Built and designed by Schnabel Engineering, Inc., this dam is regulated by the Department of Conservation and Recreation in Virginia. With a high hazard potential, the dam perimeter has not been rated for its condition assessment, but emergency action plans were last revised in June 2016 to meet safety guidelines.
Strategically positioned within the Norfolk District, the dam does not have a specified height, volume, or completion year, reflecting its unique design and function. Despite the lack of specific dimensions, its importance for water supply is emphasized as it serves the local government. The dam's association with water resource management highlights its essential role in providing sustainable water access to the surrounding community.
While details about storage capacity, spillways, and other technical aspects are limited, the Cobbs Creek Regional Water Supply Reservoir Dam Perimeter Dam (Dam C) remains a vital infrastructure for maintaining water security in Cumberland, Virginia. Its significance as a regulated structure underscores the commitment to ensuring public safety and environmental preservation in the region.
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 Cobbs Creek Regional Water Supply Reservoir Dam Perimeter Dam (Dam C)
Where does the data for Cobbs Creek Regional Water Supply Reservoir Dam Perimeter Dam (Dam C) 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.
