Summary
The dam, designed by USDA NRCS, serves the primary purpose of flood risk reduction along the TR-East Fork Big Creek. Standing at 28 feet high with a length of 540 feet, the dam has a storage capacity of 57 acre-feet and a drainage area of 12.8 square miles.
With a low hazard potential and a moderate risk assessment rating, East Fork Big Creek Dam E-25 plays a crucial role in mitigating flood risks in the area. The dam features an uncontrolled spillway with a width of 20 feet, ensuring effective water management during periods of high discharge. While the dam is currently in a not rated condition assessment, it continues to be monitored for any necessary maintenance or improvements to uphold its flood risk reduction capabilities.
Water resource and climate enthusiasts can appreciate the engineering and environmental impact of East Fork Big Creek Dam E-25, as it stands as a testament to the collaborative efforts of the Natural Resources Conservation Service and local government in safeguarding the surrounding community from flooding events. The dam's strategic location and design, coupled with its low hazard potential, make it an integral component of the region's water resource management infrastructure, contributing to the overall resilience of the area in the face of changing climate conditions.

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.
