Summary
This earthen dam stands at a height of 24.35 feet and has a storage capacity of 536 acre-feet, with a normal storage level of 73 acre-feet. Situated on the North Fork river, this dam covers a surface area of 18.6 acres and drains a watershed area of 1.26 square miles.
Managed by the Department of Conservation and Recreation in Virginia, the North Fork Wetlands Bank Dam has a high hazard potential but is currently assessed to be in satisfactory condition as of the last inspection in June 2020. While specific details on the dam's construction year and modifications are not provided, its primary purpose as an earth dam for water management is evident. Despite its remote location and lack of associated structures, the dam plays a crucial role in maintaining wetland ecosystems and regulating water flow in the region.
With its strategic location and significant storage capacity, the North Fork Wetlands Bank Dam stands as a key asset in water resource management for the area. As climate change continues to impact water availability and wetland habitats, structures like this play a vital role in ensuring a sustainable balance between human needs and ecological preservation. As such, ongoing monitoring and maintenance efforts are essential to ensure the dam's continued effectiveness in safeguarding the surrounding environment and water resources for future generations.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
