Summary
Built in 1990 by the USDA NRCS, this earth dam stands at a height of 32 feet and spans a length of 510 feet. With a storage capacity of 103 acre-feet and a drainage area of 190.08 square miles, the dam serves to mitigate flood risks along the TR-East Locust Creek.
Owned by the local government and operated by the Natural Resources Conservation Service, East Locust Creek Watershed Dam E- 51 has a low hazard potential and is classified as not rated in terms of condition assessment. With a spillway width of 30 feet and a maximum discharge of 229 cubic feet per second, the dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding events. Although the dam has not been inspected since May 1991, its risk assessment is moderate, indicating a need for ongoing monitoring and maintenance to ensure its continued effectiveness in flood risk reduction.
Overall, East Locust Creek Watershed Dam E- 51 is an essential piece of infrastructure in the area, providing valuable flood protection and water management benefits. With its strategic location and design, the dam serves as a vital resource for safeguarding the community against potential water-related hazards, highlighting the importance of continued oversight and maintenance to uphold its functionality and effectiveness in the face of changing climate conditions.

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.
