Summary
It serves the primary purpose of flood risk reduction along the West Fork Big Creek, with a height of 33.2 feet and a storage capacity of 127.3 acre-feet. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
The dam features an uncontrolled spillway with a width of 40 feet and has a maximum discharge capacity of 121 cubic feet per second. With a moderate risk rating of 3, the dam does not currently have an Emergency Action Plan (EAP) in place and lacks updated contact information for emergency situations. Despite its low hazard potential, continuous monitoring and maintenance are crucial to ensure the safety and functionality of the dam in the face of changing climatic conditions and water resource management challenges.
Overall, West Fork Big Creek Dam B-91 plays a vital role in mitigating flood risks in the area and highlights the importance of proper infrastructure for water resource and climate enthusiasts. It stands as a reminder of the ongoing need for proactive risk management measures and emergency preparedness to address potential threats and ensure the resilience of our water infrastructure systems.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
