Summary
This earth dam, with a height of 32 feet and a length of 570 feet, has a maximum storage capacity of 130 acre-feet and covers a drainage area of 129.92 square miles. Despite its age, the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
With a spillway width of 40 feet and a maximum discharge of 300 cubic feet per second, East Locust Creek Watershed Dam E-35a plays a crucial role in managing water flow during heavy rainfall events. The dam is designed to be uncontrolled and has a hydraulic height of 30 feet. The primary purpose of the dam is flood risk reduction, and it is owned and operated by the local government. While the dam has not been inspected since October 1999, it is considered to have a moderate risk level.
East Locust Creek Watershed Dam E-35a stands as a testament to effective water resource management in the region, showcasing the importance of infrastructure in mitigating flood risks and protecting communities. As climate change continues to impact weather patterns and increase the frequency of extreme events, structures like this play a crucial role in safeguarding lives and property. The dam's strategic location and design, coupled with its low hazard potential and moderate risk assessment, highlight its significance in the overall water resource and climate resilience efforts in the area.

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.
