Twin Lakes Dam # 2 dam
Twin Lakes Dam # 2
Twin Lakes Dam #2, also known as Middle Lake or Lake Shenandoah, is a privately owned earth dam located in Greene, Virginia. Designed by Ruckman Engineering, this dam serves primarily for recreational purposes, offering a serene and picturesque setting for water enthusiasts. With a height of 34 feet and a storage capacity of 658 acre-feet, it provides a tranquil escape for visitors seeking outdoor activities such as fishing, boating, and hiking.
Managed by the Department of Conservation and Recreation in Virginia, Twin Lakes Dam #2 is regulated, inspected, and enforced to ensure its safety and functionality. With a high hazard potential but a satisfactory condition assessment as of October 2021, the dam undergoes regular inspections to mitigate any risks and maintain its integrity. The surrounding area boasts a surface area of 11 acres and a drainage area of 3.9 square miles, making it an important water resource within the region.
While the dam does not have a spillway or outlet gates, it remains a popular destination for those looking to connect with nature and enjoy the beauty of Quarter Creek. Twin Lakes Dam #2 offers a peaceful retreat for water resource and climate enthusiasts, showcasing the importance of responsible dam management and conservation efforts in preserving our natural landscapes.
Dam data reference
Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Twin Lakes Dam # 2
Where does the data for Twin Lakes Dam # 2 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
