Rappahannock Dam #11 dam
Rappahannock Dam #11
Located in Rappahannock, Virginia, Rappahannock Dam #11 is a state-regulated structure under the jurisdiction of the Department of Conservation and Recreation. Standing at a height of 21.5 feet, this dam serves a primary purpose that is not specified in the available data. With a maximum storage capacity of 65.36 acre-feet and a normal storage capacity of 24.3 acre-feet, Rappahannock Dam #11 covers a surface area of 3.8 acres.
Although the condition assessment is currently listed as "Not Rated" and the hazard potential is labeled as "Undetermined," Rappahannock Dam #11 remains subject to state permitting, inspection, and enforcement. The dam has not been evaluated for risk assessment, and emergency preparedness measures such as the existence of an Emergency Action Plan (EAP) are not specified in the data. The dam's last inspection date, as well as other critical information like the year of completion and any modifications made over the years, are not available at this time.
Water resource and climate enthusiasts will be intrigued by the presence of Rappahannock Dam #11 in the Baltimore District, given its significant storage capacity and the regulatory oversight it falls under. As the structure's condition, hazard potential, and emergency preparedness are yet to be fully assessed and documented, further investigation and monitoring may be necessary to ensure the safety and effectiveness of this dam in managing water resources 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 Rappahannock Dam #11
Where does the data for Rappahannock Dam #11 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 Undetermined 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.
