Summary
Completed in 2001, this dam stands at a height of 32 feet and has a storage capacity of 143 acre-feet. With a surface area of 9 acres and a drainage area of 160 square miles, this dam plays a crucial role in protecting the surrounding Sullivan County from potential flooding events.
The dam's spillway, measuring 30 feet wide, is uncontrolled, while the outlet gates also remain uncontrolled. Despite being rated as having a low hazard potential and not yet assessed for condition, the dam is considered to have a moderate risk level. With a maximum discharge of 152.6 cubic feet per second, this structure serves multiple purposes, including fire protection, stock or small fish pond, fish and wildlife pond, in addition to flood risk reduction. As an essential infrastructure managed by the local government, East Locust Creek Watershed Dam E-120 contributes significantly to water resource management in the region.
For water resource and climate enthusiasts, East Locust Creek Watershed Dam E-120 presents an intriguing case study of sustainable infrastructure development for flood risk reduction. Managed by the local government and designed by USDA NRCS, this Earth dam stands as a vital structure in protecting Sullivan County from potential flooding events. With a storage capacity of 143 acre-feet and a moderate risk level assessment, this dam serves multiple purposes while showcasing the importance of effective water resource management in mitigating climate-related challenges.

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.
