Summary
This earth dam, standing at 16 feet in height, serves primarily for recreational purposes and holds a storage capacity of 52 acre-feet. While the dam's hazard potential is currently listed as undetermined and its condition assessment is not rated, it undergoes regular inspections with a frequency of once per year.
Situated on the TR-WHIPPONOCK river or stream, Jones Dam falls under the jurisdiction of the Norfolk District of the US Army Corps of Engineers. Despite lacking specific details on its completion date or spillway type, the dam boasts a maximum storage capacity of 52 acre-feet and a normal storage level of 18 acre-feet. While the risk assessment, emergency action plan, and inundation maps for the dam are currently not available, the structure remains under state oversight and enforcement.
Jones Dam, owned by a non-listed entity, presents an intriguing case for water resource and climate enthusiasts. With its location in a picturesque Virginia county and its role in providing recreational opportunities, the dam stands as an essential piece of infrastructure that warrants continued monitoring and assessment. As stakeholders work to ensure the safety and functionality of this key water resource, the potential for further exploration and study of Jones Dam's impact on the surrounding environment remains a compelling avenue for research and engagement.

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.
