Summary
Managed by the Department of Conservation and Recreation, this earth dam stands at a height of 8 feet and serves primarily for recreational purposes. With a storage capacity of 193 acre-feet and a surface area of 23.8 acres, the dam contributes to the local landscape while providing opportunities for leisure activities in the area.
Despite its low hazard potential and satisfactory condition assessment as of September 2019, Stonehaven Dam is subject to state regulation and inspection to ensure its safety and compliance with standards. With a drainage area of 0.63 square miles, the dam plays a crucial role in managing water resources in the region. The dam's location along the Norfolk District adds to its significance in the overall water management system, highlighting its importance for both recreational enjoyment and environmental conservation efforts in the area.
As a notable feature in the landscape of Hanover, Virginia, Stonehaven Dam represents a balance between recreational use and environmental stewardship. With its modest height and storage capacity, the dam serves as a valuable resource for the local community while also being subject to regular inspections and maintenance to guarantee its reliability and safety. As water resource and climate enthusiasts, understanding the role of dams like Stonehaven in managing water flow and providing recreational opportunities underscores the importance of responsible infrastructure management in safeguarding our natural resources for future generations.

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.
