Summary
Completed in 2004 by the USDA NRCS, this earth dam stands at a height of 22 feet and has a hydraulic height of 20 feet, with a total structural height of 33 feet. The dam has a storage capacity of 78.9 acre-feet and serves multiple purposes including fire protection, stock and small fish pond, fish and wildlife pond, and flood risk reduction.
Situated on the TR-East Locust Creek, this dam plays a crucial role in managing the water resources of the area, with a drainage area of 174.72 square miles. The dam features an uncontrolled spillway with a width of 30 feet and has a low hazard potential. Despite not being rated for condition assessment, the dam is regularly inspected every 5 years to ensure its integrity and safety. With a moderate risk assessment rating, the East Locust Creek Watershed Dam E-66 is a key infrastructure for protecting the surrounding community from potential flooding events.
Owned and operated by the local government, this dam exemplifies the collaborative effort between state and federal agencies in managing water resources and minimizing flood risks in the region. With its strategic location and design, East Locust Creek Watershed Dam E-66 stands as a testament to effective watershed management and serves as a critical asset for climate and water resource enthusiasts alike.

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.
