Summary
Completed in 1993, this earth dam stands at a height of 26.9 feet with a hydraulic height of 24 feet and a structural height of 29 feet. With a storage capacity of 146 acre-feet and a drainage area of 200 acres, this dam plays a crucial role in mitigating flooding in the region.
Owned by the local government, Upper Locust Creek L- 80 serves as a key component in the flood risk reduction efforts in the area. With a spillway width of 50 feet and a moderate risk assessment rating, this dam is designed to handle a maximum discharge of 100 cubic feet per second. Despite being uncontrolled, the dam's hazard potential is rated as low, providing a sense of security to the surrounding communities.
Although not currently rated for condition assessment, Upper Locust Creek L- 80 continues to fulfill its primary purpose of flood risk reduction effectively. With its stone core and soil foundation, this dam stands as a testament to the collaborative efforts of the Natural Resources Conservation Service and the local government in safeguarding the region against potential flooding events.

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.
