Summary

This earth dam, regulated by the Department of Conservation and Recreation in Virginia, serves an undetermined hazard potential with an inspection frequency of 1. While the condition assessment is not rated, the emergency action plan status is unrevealed, leaving the risk assessment and management measures uncertain.

Despite the lack of specific details on the dam's purposes or completion year, Prevette Dam remains a point of interest for water resource and climate enthusiasts. With its significant presence along the Dan River, the dam presents an opportunity for further exploration and research into its impact on the surrounding ecosystem and community. As a state-regulated structure with state permitting, inspection, and enforcement in place, the dam plays a crucial role in water resource management and climate resilience efforts in the region.

As water resource enthusiasts delve into the intricacies of Prevette Dam, its design, construction, and ongoing operation come into focus. The dam's location at the crossroads of federal and state jurisdictions underscores its importance in the larger landscape of water infrastructure. While questions remain about its risk assessment, emergency preparedness, and overall condition, Prevette Dam offers a compelling case study for understanding the complexities of managing water resources in a changing climate.

Dam Data Reference

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.
