Lancaster Roller Mill Dam dam
Lancaster Roller Mill Dam
The Lancaster Roller Mill Dam, located in Lancaster, Virginia, is a state-regulated structure on the CAMP PRONG river. With a height of 21 feet and a storage capacity of 776 acre-feet, this earth dam serves primarily for recreational purposes. While the hazard potential remains undetermined and the condition is not rated, the dam undergoes regular inspections by the Department of Conservation and Recreation to ensure its safety and compliance with regulatory standards.
Managed by the Norfolk District of the US Army Corps of Engineers, the Lancaster Roller Mill Dam provides a tranquil setting for outdoor enthusiasts to enjoy activities such as fishing, boating, and wildlife observation. Despite the absence of detailed information on its construction date and modifications, the dam continues to be a valuable asset in the local community, offering both recreational opportunities and environmental benefits. As climate change impacts water resources, understanding the role of dams like Lancaster Roller Mill in water management becomes increasingly crucial for sustainable planning and conservation efforts.
As water resource and climate enthusiasts explore the Lancaster Roller Mill Dam, its unique characteristics and location in the picturesque Lancaster County offer a glimpse into the intersection of human infrastructure and natural landscapes. With ongoing regulatory oversight and commitment to safety measures, this dam stands as a testament to the importance of balancing recreational access with environmental stewardship in the face of changing climate conditions. As stakeholders work together to address potential risks and enhance resilience, the Lancaster Roller Mill Dam remains a symbol of the harmonious coexistence between water resources and community well-being.

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 Lancaster Roller Mill Dam
Where does the data for Lancaster Roller 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.
