Lancaster County Dam #3 dam
Lancaster County Dam #3
Lancaster County Dam #3, located in Virginia, is a state-regulated dam under the jurisdiction of the Department of Conservation and Recreation. Standing at a height of 13 feet with a length of 200 feet, this dam provides a storage capacity of 133.17 acre-feet and a surface area of 15.27 acres. While the dam's hazard potential and condition assessment are currently labeled as undetermined and not rated, respectively, it is regularly inspected with a frequency of 1 year to ensure its safety and stability.
Although specific details about the dam's primary purpose, construction year, and spillway type are not listed, Lancaster County Dam #3 remains an essential structure for water resource management in the region. Its geographical coordinates of 37.678 latitude and -76.3826 longitude place it within the Norfolk District and make it a key component in the area's water infrastructure. While the dam's emergency action plan status and risk assessment measures are not provided, its presence and maintenance play a crucial role in mitigating potential flooding risks and ensuring water resource sustainability for the surrounding community.
Overall, Lancaster County Dam #3 serves as a vital asset for water management in Lancaster, Virginia, offering storage capacity, flood control, and environmental protection. While its current condition assessment is not rated, regular inspections and state regulation help to monitor and address any potential safety concerns. As a state-regulated structure with a significant storage capacity, this dam plays a crucial role in ensuring the efficient and sustainable use of water resources in the region, making it an essential part of the local climate and water resource management efforts.

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 County Dam #3
Where does the data for Lancaster County Dam #3 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.
