Raven Knob Lake Dam dam
Raven Knob Lake Dam
Raven Knob Lake Dam in Surry, North Carolina, is a private earth dam completed in 1950 for recreational purposes. Located in Blevins Store, the dam stands at a structural height of 39.5 feet and a hydraulic height of 33.5 feet, with a total length of 351 feet. The dam has a normal storage capacity of 194 acre-feet, providing a surface area of 17.3 acres for outdoor activities such as fishing, boating, and picnicking.
Managed by the North Carolina Dam Safety Program, Raven Knob Lake Dam is subject to state regulations, inspections, and enforcement to ensure its safety and integrity. The dam's hazard potential is classified as significant, but its condition assessment as of April 2020 was deemed satisfactory. With a drainage area of 2000 acres and a maximum storage capacity of 273 acre-feet, the dam plays a crucial role in water resource management and flood control for the surrounding area along Endicott Creek.
Overall, Raven Knob Lake Dam serves as a vital recreational and water resource structure in Surry County, North Carolina. With its scenic setting and important function in the region's water management system, the dam continues to provide opportunities for outdoor recreation while meeting state safety and regulatory standards for dam operations.

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 Raven Knob Lake Dam
Where does the data for Raven Knob Lake 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 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.
