Summary

This rockfill dam, standing at a height of 121 feet with a hydraulic height of 109 feet, serves to manage the waters of Sugar Camp Run. With a storage capacity of 406 acre-feet and a surface area of 10 acres, this dam plays a crucial role in regulating water flow in the region.

Despite its high hazard potential, Momentive Landfill #2 Dam has been deemed to be in satisfactory condition as per the most recent assessment in September 2014. The dam undergoes inspections every two years, with the last inspection conducted in December 2016. It is regulated by the West Virginia Department of Environmental Protection and has state permitting, inspection, and enforcement in place to ensure its safe operation.

With its strategic location and significant role in water management, Momentive Landfill #2 Dam stands as a critical infrastructure in Tyler County. Water resource and climate enthusiasts will find this dam's design and operation noteworthy, as it contributes to the overall water security and flood control measures in the area.

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.
