Lancaster Dam dam
Lancaster Dam
Lancaster Dam, located in Cumberland, Virginia, is a state-regulated structure managed by the Department of Conservation and Recreation. This earth dam stands at a height of 27 feet and serves primarily for irrigation purposes, with recreational activities also being supported. Despite its undetermined hazard potential and not being rated for condition assessment, the dam has a storage capacity of 37 acre-feet and is inspected annually for safety and compliance.
Owned by an unspecified entity, Lancaster Dam has not undergone any significant modifications since its completion. With a spillway type and dimensions not specified, the dam's associated structures and inspection frequency suggest ongoing monitoring and maintenance efforts to ensure its integrity. While emergency action plans and inundation maps are not currently prepared, the dam's risk management measures and risk assessments remain unspecified, leaving room for further evaluation of potential hazards and response protocols.
Overall, Lancaster Dam provides essential irrigation support while offering recreational opportunities in the Cumberland region of Virginia. As a state-regulated structure, it plays a crucial role in water resource management, although its hazard potential and condition assessment status warrant continued attention and potential updates to risk management protocols. With annual inspections and a storage capacity of 37 acre-feet, Lancaster Dam remains an important feature for water resource and climate enthusiasts to monitor in the region.

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 Dam
Where does the data for Lancaster 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.
