Summary
Completed in 1999 by the Natural Resources Conservation Service, this earth dam stands at a height of 19 feet and has a maximum storage capacity of 50 acre-feet. With a drainage area of 174.72 square miles, the dam plays a crucial role in protecting the surrounding community from potential flooding events.
The primary purpose of Dam E-8 is flood risk reduction, although it also serves secondary purposes such as fire protection and creating a habitat for fish and wildlife. With a low hazard potential and a moderate risk assessment rating, the dam is considered to be in good condition, albeit not officially rated. Despite not having outlet gates, the uncontrolled spillway with a width of 20 feet ensures that excess water can be safely discharged during heavy rainfall events.
Overall, East Locust Creek Watershed Dam E-8 stands as a testament to effective water resource management and climate mitigation efforts in the region. As a crucial piece of infrastructure designed to protect against flooding and support the local ecosystem, this dam showcases the importance of sustainable engineering practices in ensuring the safety and well-being of communities in vulnerable areas.

Dam Data Reference
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.
