Summary
Standing at 11 feet high and 311 feet long, the dam has a storage capacity of 95 acre-feet, with a normal storage of 41 acre-feet. Despite its relatively small size, Miller Dam is regulated by the Department of Conservation and Recreation in Virginia, ensuring that it meets state inspection, enforcement, and permitting requirements.
Although the hazard potential of Miller Dam is currently categorized as "Undetermined" and its condition is "Not Rated", the dam is subject to regular inspections with a frequency of once per year. The dam has not been modified in recent years, and there is no Emergency Action Plan (EAP) in place as of the last data update in April 2021. While the risk assessment, risk management measures, and other emergency preparedness aspects of the dam are not specified, Miller Dam remains an integral part of the local water resource infrastructure for irrigation purposes in the area.
As water resource and climate enthusiasts explore Miller Dam's role in water management along the TR-MATTOWOMAN CREEK, they can appreciate its modest yet significant contribution to agricultural practices in the region. With its connection to a federal agency (Norfolk District) and the oversight of the Department of Conservation and Recreation in Virginia, Miller Dam stands as a testament to responsible water resource management and the importance of maintaining infrastructure for sustainable irrigation practices in the face of changing climate conditions.

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.
