Summary
This earth dam stands at a height of 22.4 feet and has a storage capacity of 64 acre-feet, with a normal storage level of 16 acre-feet. Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level.
With a spillway width of 20 feet and a maximum discharge of 40 cubic feet per second, East Fork Big Creek Dam E-32 is equipped to handle excess water in times of heavy rainfall. The dam's primary purpose is flood risk reduction, serving as a key component in protecting the surrounding area from potential flooding events. Although the dam is not currently rated for its condition, it continues to play a vital role in water resource management for the region.
Managed by the local government, this dam stands as a testament to the collaborative efforts between federal agencies and local authorities in safeguarding communities against the impacts of extreme weather events. As climate change continues to pose challenges to water resource management, structures like East Fork Big Creek Dam E-32 highlight the importance of proactive measures in mitigating flood risks and ensuring the resilience of our infrastructure in the face of a changing climate.

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.
