Summary
Constructed in 1990 by the USDA NRCS, this earth-type dam stands at 20 feet high and spans 410 feet in length, with a storage capacity of 86 acre-feet. Serving the primary purpose of flood risk reduction, it is situated on the TR-East Locust Creek and is managed by the local government.
With a low hazard potential and a moderate risk assessment rating, East Locust Creek Watershed Dam E-47 plays a crucial role in mitigating flood risks in the region. Despite being unregulated by the state, this dam has not been inspected since 1991 and is currently not rated in terms of condition assessment. While it lacks outlet gates, it features an uncontrolled spillway with a width of 30 feet, and has a drainage area of 270.08 square miles, providing essential protection to the surrounding area.
Overall, East Locust Creek Watershed Dam E-47 stands as a testament to effective flood risk reduction efforts in the region, showcasing the importance of sustainable water resource management and climate adaptation. As climate change continues to pose challenges to water infrastructure, this dam serves as a vital asset in safeguarding communities and ecosystems from the impacts of extreme weather events, highlighting the critical role of such structures in building resilience in the face of a changing climate.

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.
