Summary
This earth dam stands at a height of 18 feet and serves primarily for irrigation purposes. With a storage capacity of 84 acre-feet, Grays Dam plays a crucial role in providing water for agricultural needs in the region.
Managed and regulated by the Department of Conservation and Recreation in Virginia, Grays Dam is subject to regular inspections and enforcement to ensure its safety and functionality. While its hazard potential is currently undetermined and its condition remains unrated, the dam continues to support the local community by providing water for irrigation and recreational activities. Despite its modest size and infrastructure, Grays Dam plays a significant role in water resource management in the area.
As a key structure in the Norfolk District, Grays Dam underscores the importance of sustainable water management practices in the face of climate change. Its location in Middlesex, Virginia, highlights the critical role that such dams play in supporting local agriculture and recreation, while also emphasizing the need for ongoing monitoring and maintenance to ensure their safety and efficacy in the long term.

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.
