Summary
3, also known as Lower Lake or Lake Skyline, is a private-owned earth dam located in Greene, Virginia, along Quarter Creek. Designed by Ruckman Engineering, PLC, this dam serves primarily for recreational purposes with a storage capacity of 162 acre-feet. With a height of 29 feet and a length of 500 feet, it creates a surface area of 4 acres and drains a watershed area of 4.17 square miles.
Despite its recreational benefits, Twin Lakes Dam No. 3 poses a significant hazard potential with a poor condition assessment as of July 2017. The Department of Conservation and Recreation in Virginia regulates this dam, ensuring regular inspections and enforcement of safety measures. While the last inspection took place in July 2017, there is a need for ongoing monitoring and maintenance to address the poor condition and mitigate potential risks associated with this aging structure.
As water resource and climate enthusiasts, understanding the state-regulated status, design details, and hazard potential of Twin Lakes Dam No. 3 can shed light on the importance of proper dam management and maintenance. With a focus on recreational use and significant storage capacity, this dam serves as a vital piece of infrastructure in the region, requiring attention to ensure safety and sustainability for both the environment and the community it serves.

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.
