Summary
Completed in 1985, this earth dam stands at a height of 26.5 feet and spans a length of 420 feet, with a storage capacity of 64 acre-feet. The primary purpose of this dam is flood risk reduction, serving as a crucial asset in protecting the local community from potential water-related hazards.
The dam, situated on the TR-East Fork Big Creek, is owned by the local government and is not regulated by the state. With a low hazard potential and a moderate risk assessment, East Fork Big Creek Dam E- 92 plays a significant role in mitigating the impacts of extreme weather events on the surrounding area. Despite being ungraded for its condition, this structure represents a key component of the region's water resource management infrastructure.
Managed by the Natural Resources Conservation Service and located in a picturesque setting within the Rock Island District, East Fork Big Creek Dam E- 92 stands as a testament to the collaborative efforts of various agencies in safeguarding the local community from flood risks. With its uncontrolled spillway and stone core, this dam symbolizes the importance of sustainable water resource management practices in addressing the challenges posed by climate change and ensuring the resilience of communities in the face of natural disasters.

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.
