Summary
This earth dam stands at a height of 26 feet and has a length of 326 feet, with a primary purpose of irrigation. Although its hazard potential is currently labeled as "Undetermined" and its condition assessment is "Not Rated", the dam is regulated by the Department of Conservation and Recreation in Virginia.
Situated in the Norfolk District, Sanderson Dam has a storage capacity of 46 acre-feet and is used for irrigation purposes. Despite lacking specific data on its completion year, normal storage capacity, and other technical details, the dam plays a crucial role in water resource management in the region. With the dam being state regulated, inspected, and enforced, it serves as a key infrastructure for water supply and management in Amelia, Virginia.
While specific information about the dam's risk assessment, emergency action plan, and inundation maps is not provided, the presence of regular inspections and state oversight indicates a commitment to ensuring the safety and functionality of Sanderson Dam. With its location in a county with a rich history and significant agricultural activities, the dam's role in supporting irrigation and water resource management makes it an important asset for both the local community and the broader region.

Dam Data Reference
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.
