Summary

Managed by the Department of Conservation and Recreation, this dam serves a vital role in water resource management and flood control in the region. Although the hazard potential of the dam is currently undetermined, regular inspections and maintenance ensure its structural integrity and safety.

The dam, completed at an unspecified year, spans a length of 460 feet and has a surface area of 6.04 acres. While its specific purposes and design details are not provided in the data, its importance in providing water storage and flood protection to the area is evident. With a latitude of 37.3573 and longitude of -78.1884, Amelia County Dam # 4 stands as a key infrastructure asset in the Norfolk District, contributing to the overall water resource management efforts in the state.

While the condition assessment of the dam is listed as 'Not Rated', its emergency action plan status and risk assessment details are not available in the data. However, with its state-regulated status and regular inspections, Amelia County Dam # 4 remains a crucial element in the region's water resource infrastructure. As climate change impacts water resources and extreme weather events become more frequent, the role of dams like this in ensuring water security and mitigating flood risks becomes increasingly important for the community and the environment.

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.
