Summary

4 Pond, located in Goochland, Virginia, is a state-regulated earth dam with a height of 36 feet that serves as a tributary to the James River. Owned by a not listed entity, this dam has a storage capacity of 48 acre-feet and is under the jurisdiction of the Department of Conservation and Recreation. Although its hazard potential is labeled as undetermined and its condition assessment is not rated, the dam is inspected yearly, indicating an active commitment to monitoring its safety and integrity.

While lacking specific details on construction year or purpose, No. 4 Pond's critical infrastructure status is evident through its significance in the region's water resource management. The presence of state-permitting, inspection, and enforcement processes, as well as the involvement of state agencies in regulatory oversight, underscores the importance of this dam in ensuring water supply and flood control for the local community. With a prominent position in the Norfolk District and with Abigail Davis Spanberger (D) as the representative, the dam's role in water resource sustainability and climate resilience cannot be understated.

As an essential component of the water management system in the area, No. 4 Pond represents a critical piece of infrastructure that requires ongoing attention and maintenance to mitigate potential risks and ensure the safety of surrounding communities. With its proximity to the James River and its regulated status, the dam serves as a vital link in the region's water supply chain and underscores the interconnected nature of water resources and climate adaptation efforts. Continued monitoring and adherence to regulatory standards will be key in securing the resilience and sustainability of this important water resource asset.

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.
