Summary

Constructed in 1978 by the USDA NRCS, this earth dam stands at 84 feet in height and spans 655 feet in length, with a storage capacity of 1230 acre-feet and a drainage area of 4.84 square miles. The dam plays a crucial role in protecting the surrounding area from flooding, with a spillway designed for uncontrolled release of excess water during high flow events.

Managed by local government authorities and regulated by the West Virginia Department of Environmental Protection's Division of Water and Waste Management, Wheeling Creek No.18 has a high hazard potential but is currently in satisfactory condition according to the latest assessment conducted in April 2013. The dam is equipped with uncontrolled outlet gates and has a hydraulic height of 81 feet. While the risk assessment for the structure is moderate, the emergency action plan (EAP) status and inundation maps preparation are noted as areas that require attention and improvement. Overall, Wheeling Creek No.18 serves as a critical infrastructure in safeguarding the community against potential flood events and highlights the importance of proactive risk management measures in ensuring its continued efficacy.

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.
