Summary

3 is a flood risk reduction dam located in Berryville, West Virginia, along Warm Spring Run. Constructed in 1955 by the USDA NRCS, this dam stands at 48 feet tall with a hydraulic height of 40 feet and a length of 335 feet. It serves the primary purpose of flood risk reduction, with a normal storage capacity of 6 acre-feet and a maximum storage of 110 acre-feet. Despite its high hazard potential, the dam is deemed to be in satisfactory condition as of the last inspection in September 2014.

Managed by the West Virginia Department of Environmental Protection's Division of Water and Waste Management (DWWM), Warm Springs No. 3 is regulated, permitted, inspected, and enforced by the state authorities. It operates with uncontrolled spillways and outlet gates, with a rock and soil foundation supporting its earth dam structure. The dam's risk assessment indicates a moderate level of risk, warranting ongoing monitoring and potential risk management measures to ensure the safety of the surrounding area in the event of a flood. With a rich history and vital role in flood protection, Warm Springs No. 3 stands as a critical infrastructure for water resource management in Morgan County, West Virginia.

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.
