Summary
Built in 2007 by the USDA NRCS, this dam serves multiple purposes including flood risk reduction, fire protection, and providing a habitat for fish and wildlife. With a height of 28 feet and a length of 445 feet, it has a storage capacity of 244.3 acre-feet and covers a surface area of 7 acres.
Although classified as having a low hazard potential, the dam has a moderate risk assessment due to its location along the TR-LOCUST CREEK and its drainage area of 190 square miles. The spillway type is uncontrolled with a width of 40 feet, and the outlet gates are also uncontrolled. Despite not having a current condition assessment, the dam is still operational and contributes to the overall management of flood risk in the area.
Overall, Upper Locust Creek L-152 is an essential infrastructure for flood risk reduction in the region, providing environmental benefits and serving as a valuable resource for water resource and climate enthusiasts. Its construction and management by the Natural Resources Conservation Service ensure its effectiveness in mitigating potential hazards and protecting the surrounding community from the impacts of flooding.

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.
