Roberts Dam dam
Roberts Dam
Roberts Dam, located in Grayson, Virginia, is a privately owned earth dam with a primary purpose of recreation. Standing at a height of 30 feet, the dam provides storage of 32 acre-feet of water for various recreational activities. Despite its relatively small size, Roberts Dam is regulated by the Department of Conservation and Recreation in Virginia, ensuring that it meets state inspection, permitting, and enforcement requirements.
While the condition assessment of Roberts Dam is currently listed as "Not Rated," its hazard potential is determined to be "Undetermined." The dam has an inspection frequency of once per year, indicating a commitment to maintaining its safety and integrity. However, details such as the year of completion, storage capacity, and specific dimensions of the dam are not provided in the data, leaving some aspects of its design and history unclear.
Overall, Roberts Dam serves as a vital resource for recreational purposes in the area, providing residents and visitors with opportunities for water-based activities. As a privately owned structure in a regulated state jurisdiction, the dam is subject to regular inspections and enforcement measures to ensure the safety of those who enjoy its benefits. With its scenic location and potential for water storage, Roberts Dam represents a valuable asset in the management of water resources and climate resilience efforts in Virginia.
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 Roberts Dam
Where does the data for Roberts 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 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.
