Summary
Built in 1994 by the USDA NRCS, this earth dam stands at a height of 28.8 feet and spans 460 feet in length. With a storage capacity of 62 acre-feet and a drainage area of 430 acres, this dam plays a crucial role in mitigating flood risks in the region.
Despite its low hazard potential, Upper Locust Creek L-145 is rated as having a moderate risk level. The dam features an uncontrolled spillway with a width of 20 feet and has not been modified since its completion. While the condition assessment is marked as "Not Rated," the dam is regularly inspected by the Natural Resources Conservation Service to ensure its continued effectiveness in flood risk reduction.
Owned and operated by the local government, Upper Locust Creek L-145 serves as a key infrastructure for water resource management in the area. With its strategic location and design, this dam plays a vital role in protecting the community from potential flood events and highlights the importance of sustainable water management practices in the face of changing climate conditions.

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.
