Stone Dam dam
Stone Dam
Stone Dam, located in Pittsylvania County, Virginia, is a privately owned structure that is regulated by the Department of Conservation and Recreation. This earth dam stands at a height of 24 feet and has a length of 640 feet, with a storage capacity of 57 acre-feet and a surface area of 4.5 acres. The dam's primary purpose and associated structures are not specified in the data, and its hazard potential is listed as "Undetermined" with a condition assessment of "Not Rated".
Although the dam's condition and emergency preparedness status are not provided, it is noted that inspections are conducted regularly with an inspection frequency of 1. Stone Dam's risk assessment, management measures, and inundation maps are also not available in the data. The dam is not classified as being under the jurisdiction of the U.S. Army Corps of Engineers, and it does not have any designated emergency action plans or updated emergency contacts.
Overall, Stone Dam presents an intriguing case study for water resource and climate enthusiasts due to its private ownership, state regulation, and the lack of comprehensive data on its condition and risk management strategies. This structure serves as a reminder of the importance of monitoring and maintaining dams to ensure safety and prevent potential hazards to nearby communities and ecosystems. Further research and analysis of Stone Dam could provide valuable insights into the complexities of managing water resources and infrastructure in the face of changing climate conditions.

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 Stone Dam
Where does the data for Stone 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.
