Summary

With a height of 16.5 feet and a storage capacity of 98.01 acre-feet, this dam plays a crucial role in water resource management in the area. Although the hazard potential and condition assessment of the dam are currently undetermined and not rated, it is regularly inspected by state authorities to ensure public safety.

The dam, with a structural height of 16.5 feet and a length of 350 feet, serves as a vital infrastructure for flood control and water storage in Lancaster County. With a normal storage capacity of 58.52 acre-feet and a surface area of 13.3 acres, this dam plays a significant role in managing water resources in the region. Despite its condition assessment being not rated, the dam is equipped with emergency action plans, although their specifics are not provided in the data.

Managed by the Norfolk District of the US Army Corps of Engineers, Lancaster County Dam #2 is a key component of the water resource infrastructure in the area. With its location in a state-regulated jurisdiction and regular inspections, this dam ensures the safety and security of local residents while contributing to the effective management of water resources and climate resilience in Lancaster County, Virginia.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
