Summary

This earth dam stands at a height of 41 feet with a hydraulic height of 32 feet and a length of 550 feet. It has a maximum storage capacity of 137.2 acre-feet and a normal storage of 36.7 acre-feet, serving as a crucial infrastructure for managing water resources in the region.

Despite being classified as having a low hazard potential, West Fork Big Creek Dam B- 63 is subject to moderate risk, according to the data available. The dam features an uncontrolled spillway with a width of 40 feet and has not been rated for its condition assessment. While the dam does not have outlet gates, it plays a significant role in flood risk management for the surrounding area, with a drainage area of 85 square miles and a maximum discharge capacity of 44.2 cubic feet per second.

With its strategic location and design, West Fork Big Creek Dam B- 63 serves as a vital component in the overall water resource infrastructure of the region. As water resource and climate enthusiasts, it is important to recognize the role of such dams in mitigating flood risks and ensuring sustainable water management practices to protect communities and ecosystems along the West Fork Big Creek.

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.
