Summary
Built with an earth design and standing at a height of 20 feet, the dam has a storage capacity of 50 acre-feet, with a normal storage level of 24 acre-feet. Despite its importance in providing water for agricultural needs, the dam's hazard potential and overall condition remain undetermined, as it has not been rated for its structural integrity.
Managed by the Department of Conservation and Recreation in Virginia, Marshall Dam falls under state jurisdiction with permits for operation, regular inspections, and enforcement measures in place. However, details such as the construction year, dam length, and spillway type are not listed, suggesting gaps in available information. With Denver Riggleman as the local congressional representative, the dam's emergency action plan status, risk assessment, and management measures also remain unspecified, raising questions about its readiness for potential incidents.
As an essential component of the water infrastructure in Lunenburg County, Marshall Dam's significance for irrigation highlights the need for comprehensive assessments and risk management strategies to ensure its long-term safety and functionality. Water resource and climate enthusiasts may find interest in exploring further details about the dam's operation, maintenance, and emergency preparedness to support sustainable water management practices in the region.

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.
