Summary
Completed in 1991, this earth dam stands at 24 feet high and spans 540 feet in length, with a maximum storage capacity of 167 acre-feet. Situated on the TR-East Locust Creek, this dam plays a vital role in safeguarding the surrounding area from potential flooding events, with a low hazard potential and moderate risk assessment rating.
Owned and operated by the local government, East Locust Creek Watershed Dam E-4 signifies a collaborative effort to manage water resources effectively. With a drainage area of 124.8 square miles and a normal storage capacity of 46 acre-feet, this dam serves as a crucial infrastructure for flood control in the region. Despite its importance, the dam's condition assessment remains unrated, indicating a need for further evaluation to ensure its continued functionality and safety.
With a spillway width of 20 feet and no outlet gates, East Locust Creek Watershed Dam E-4 showcases a commitment to flood risk reduction and water management in the area. While the dam's emergency action plan and risk management measures are yet to be fully assessed, its strategic location and design highlight the significance of sustainable water resource management practices in mitigating potential hazards and ensuring the resilience of communities in the face of changing climate patterns.

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.
