Summary
With a primary purpose of irrigation and secondary purpose of recreation, this earth dam stands at a height of 9 feet and has a storage capacity of 107 acre-feet. While the condition assessment is not rated and the hazard potential is undetermined, the dam is subject to regular state inspection, permitting, and enforcement by the Department of Conservation and Recreation.
Located within the Norfolk District of the US Army Corps of Engineers, Rosegill Upper Dam plays a crucial role in water resource management in the region. Although the dam's design and construction details are not specified, its presence contributes to the overall water supply for irrigation while also offering recreational opportunities for the local community. As a regulated structure, it undergoes periodic inspections and enforcement measures to ensure its safety and functionality.
Water resource and climate enthusiasts will find Rosegill Upper Dam a significant point of interest in the region, as it represents a key component of the water infrastructure system in Middlesex, Virginia.

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.
