Summary
Constructed in 2006 by the USDA NRCS, this earth dam stands at a height of 30 feet and has a storage capacity of 137.2 acre-feet. With a drainage area of 890 acres and a maximum discharge of 204.4 cubic feet per second, this dam plays a crucial role in managing water flow in the TR-LOCUST CREEK watershed.
The dam features an uncontrolled spillway with a width of 50 feet and outlet gates that are also uncontrolled. Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level. While it has not been rated for its condition assessment, the dam continues to serve its purpose effectively in protecting the local community and wildlife habitats. With its strategic location and design, Upper Locust Creek L- 86 stands as a testament to effective water resource management and climate resilience efforts in the region.
As a key structure in the flood risk reduction system, Upper Locust Creek L- 86 provides valuable insights for water resource and climate enthusiasts. Its construction and design by the Natural Resources Conservation Service showcase the importance of proactive measures in mitigating potential disasters. With the support of local government ownership and oversight, this dam serves as a critical asset in safeguarding the environment and community against the impacts of extreme weather 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.
