Summary
Completed in 1990, this earth dam stands at a height of 34 feet and spans 430 feet in length, with a storage capacity of 115 acre-feet and a surface area of 5 acres. It serves the primary purpose of flood risk reduction along the East Locust Creek, offering protection to the surrounding Sullivan County community.
Despite its low hazard potential and moderate risk assessment, East Locust Creek Watershed Dam E-77 has not been state-regulated or inspected since its completion in 1991. With a spillway width of 14 feet and a maximum discharge capacity of 100 cubic feet per second, this dam plays a vital role in managing water flow in the region. Although not rated for its condition, the dam's structure and design, along with its stone core and soil foundation, demonstrate its resilience and effectiveness in flood control.
As climate change continues to impact precipitation patterns and water resource management, the East Locust Creek Watershed Dam E-77 serves as a critical asset for the local government in maintaining the safety and well-being of residents in Sullivan County. With its strategic location and design by the Natural Resources Conservation Service, this dam stands as a testament to effective flood risk reduction efforts in the region.

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.
