Summary

Situated on the Alum Run stream, this earth-type dam stands at a height of 71 feet and has a storage capacity of 1910 acre-feet. With a normal storage capacity of 170 acre-feet and a surface area of 15 acres, Stony Creek Dam #10 plays a crucial role in managing water resources in the region.

Managed by the Department of Conservation and Recreation, this dam has a high hazard potential but is currently in satisfactory condition as of the last assessment in October 2019. While specific construction and modification dates are not provided, the dam undergoes regular inspections every year to ensure its structural integrity. With a designated emergency action plan and emergency contacts in place, Stony Creek Dam #10 is equipped to handle potential risks and ensure the safety of the surrounding community.

For water resource and climate enthusiasts, Stony Creek Dam #10 offers a fascinating example of infrastructure designed to mitigate flood risks and protect the local environment. Its strategic location and purposeful design highlight the importance of effective water management in maintaining the ecological balance of the region. As a vital component of the water infrastructure in Shenandoah, Virginia, this dam serves as a critical resource for both flood control and recreational activities, showcasing the intersection of human ingenuity and environmental stewardship in water resource management.

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. 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

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, 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.
