Summary
Situated in Washington County, Virginia, the dam serves a primary purpose of recreation along the Brumley Creek. With a height of 32.3 feet and a length of 560 feet, the dam has a storage capacity of 1,975 acre-feet and covers a surface area of 59.7 acres.
Regulated by the Department of Conservation and Recreation, the Hidden Valley Lake Dam poses a high hazard potential but is currently assessed to be in fair condition as of February 2021. With regular state inspections and enforcement measures in place, the dam ensures the safety of its surrounding community and recreational users. Its location in a picturesque natural setting makes it a popular destination for water resource and climate enthusiasts seeking outdoor activities in the region.
Despite its relatively small drainage area of 1.7 square miles, the dam plays a crucial role in providing recreational opportunities and maintaining water resources in the area. With its earth dam structure and regulated state jurisdiction, Hidden Valley Lake Dam stands as a testament to responsible water management and environmental stewardship in Virginia.

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.
