Summary
This earth dam stands at a height of 26 feet and has a structural height of 28 feet, with a length of 450 feet and a storage capacity of 99 acre-feet. The dam is classified as low hazard potential and is currently not rated for condition assessment.
With a drainage area of 108.8 square miles, East Fork Big Creek Dam E-82 plays a crucial role in mitigating flood risks and stabilizing grades in the region. The dam's uncontrolled spillway, with a width of 35 feet, is designed to handle a maximum discharge of 70 cubic feet per second. Despite not being state regulated or inspected, the dam's moderate risk assessment (3 out of 5) highlights the importance of continued monitoring and maintenance to ensure its effectiveness in flood management.
Overall, East Fork Big Creek Dam E-82 serves as a vital infrastructure for local flood control efforts in the area, emphasizing the significance of sustainable water resource management practices. As climate change continues to impact weather patterns and water availability, the dam's role in protecting communities from flood risks becomes increasingly crucial. Collaboration between local government agencies and the USDA NRCS is essential to ensure the ongoing safety and efficiency of this important flood protection structure.

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.
