Summary
Completed in 1999, this earth dam stands at a height of 23 feet and has a storage capacity of 98 acre-feet. With a primary purpose of flood risk reduction, the dam also serves other functions such as fire protection and supporting wildlife habitats.
Situated on a tributary of East Locust, this dam plays a crucial role in managing water resources in Sullivan County. With a drainage area of 140.16 square miles and a maximum discharge capacity of 142 cubic feet per second, the dam helps regulate water flow and reduce the risk of flooding in the region. Despite its low hazard potential, the dam's condition assessment is currently marked as 'Not Rated', highlighting the need for regular inspections and maintenance to ensure its continued effectiveness.
Overall, East Locust Creek Watershed Dam E-12 is a vital infrastructure project that contributes to the resilience of the local community against natural disasters. As climate change continues to impact water resources, structures like this dam play a critical role in protecting both human lives and the environment. With proper management and oversight, this dam will continue to serve as a valuable asset in safeguarding the region's water supply and reducing flood risks for years to come.

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.
