Summary
With a height of 15 feet and a storage capacity of 72 acre-feet, this dam serves as a crucial structure in the management of water resources in the area. The dam is situated on a tributary to the James River and covers a surface area of 9 acres.
Despite its importance in flood risk reduction, Mclean, Lee & Hammons, John Q Lake #3 has a high hazard potential and has not been rated for its current condition. The last inspection date recorded was in 1979, and the inspection frequency is listed as 0. With no emergency action plan prepared and limited information on risk assessment and management measures, there is a need for increased attention and monitoring of this dam to ensure its continued effectiveness in mitigating flooding impacts and protecting the surrounding area.
For water resource and climate enthusiasts, Mclean, Lee & Hammons, John Q Lake #3 presents a unique case study in private dam ownership and management. As the dam is not state-regulated or permitted, there are questions surrounding its long-term maintenance and structural integrity. The lack of recent inspections and emergency preparedness measures highlights the importance of proactive monitoring and risk assessment for sustainable water resource management 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.
