Roanoke Creek Dam # 70a dam
Roanoke Creek Dam # 70a
Roanoke Creek Dam # 70a, also known as Keysville Lake or Keysville Reservoir, is a significant earth dam located in Keysville, Virginia, owned by the local government. The dam serves multiple purposes including flood risk reduction, recreation, and most importantly, water supply. It stands at a height of 36.1 feet with a length of 720 feet, providing a storage capacity of 1,506 acre-feet and a surface area of 42.3 acres.
Managed by the Department of Conservation and Recreation in Virginia, Roanoke Creek Dam # 70a is state-regulated and undergoes regular inspections to ensure its safety. The dam has been assessed as satisfactory in condition, with a significant hazard potential due to its location in the area. The last inspection in November 2017 deemed the dam to be in a satisfactory state, meeting guidelines and regulations for emergency action plans.
With a drainage area of 2.74 square miles and a maximum discharge capacity of 5,600 cubic feet per second, Roanoke Creek Dam # 70a plays a crucial role in water resource management in the region. Its construction and maintenance are carefully monitored to protect the surrounding community and ensure a reliable water supply for the area.
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 Roanoke Creek Dam # 70a
Where does the data for Roanoke Creek Dam # 70a 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 Significant 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.
