Old Stone Mill Dam dam
Old Stone Mill Dam
The Old Stone Mill Dam, located in Pittsylvania, Virginia, is a historic masonry dam standing at 23 feet in height, with a storage capacity of 64 acre-feet. This dam, constructed on a tributary to the Roanoke River, serves a primary purpose that is classified as 'Other,' with no specific designation provided for its original completion year. Despite its age and undetermined hazard potential, the dam remains under state regulation and jurisdiction, with the Department of Conservation and Recreation responsible for permitting, inspection, and enforcement.
Owned privately, the Old Stone Mill Dam is not associated with any federal agencies in terms of funding, design, construction, regulation, or operation. The dam's condition assessment is marked as 'Not Rated,' indicating a lack of recent evaluation of its structural integrity and safety. While the risk assessment, emergency action plan, and inundation maps are currently unavailable, the dam's risk management measures and compliance with guidelines remain unspecified, leaving its resilience to potential hazards uncertain.
Water resource and climate enthusiasts intrigued by the Old Stone Mill Dam's historical significance and structural details may find the lack of comprehensive data on its current condition and risk management measures concerning. With its location in a picturesque setting and ties to the region's water management history, this masonry dam presents an opportunity for further exploration and assessment to ensure its continued safety and preservation in the face of evolving environmental challenges.
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 Old Stone Mill Dam
Where does the data for Old Stone Mill 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.
