Summary
This earth dam stands at a height of 27 feet and has a capacity of storing 47 acre-feet of water, with a normal storage level of 11 acre-feet. The dam, with a length of 310 feet, serves the primary purpose of flood risk reduction and is classified as low hazard potential with a moderate risk assessment score of 3.
The East Fork Big Creek Dam E-52 is managed by local government agencies with no state regulation or inspection requirements. Although not rated for its condition, the dam has not undergone any modifications since its completion. The spillway, with a width of 20 feet, is uncontrolled and the dam has no outlet gates. Despite its low hazard potential, the dam is a critical infrastructure in mitigating flood risks in the region, with a maximum discharge rate of 40 cubic feet per second and a drainage area of 281.6 square miles. Water resource and climate enthusiasts will appreciate the essential role that the East Fork Big Creek Dam E-52 plays in managing water flow and protecting the surrounding areas from potential flood events.

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.
