Summary
The dam stands at a height of 33.9 feet and serves primarily for flood risk reduction, with additional purposes including fire protection, stock or small fish pond, fish and wildlife pond. It has a storage capacity of 205.4 acre-feet and covers a surface area of 3 acres, with a drainage area of 340 acres.
Situated on TR-Locust Creek in Sullivan County, Missouri, Upper Locust Creek L-157 is managed by the Natural Resources Conservation Service and falls under the jurisdiction of the state with no state regulation. With a low hazard potential and a moderate risk assessment rating, the dam features an uncontrolled spillway type and outlet gates. Despite not having a condition assessment rating, the dam's risk management measures indicate a proactive approach to maintaining its structural integrity and ensuring public safety in the event of emergencies.
For water resource and climate enthusiasts, Upper Locust Creek L-157 presents an intriguing case study in dam infrastructure for flood risk reduction in a rural setting. With its unique design and multiple uses, this earth dam serves as an important water management tool in the region, highlighting the importance of sustainable practices in mitigating environmental risks and ensuring community resilience in the face of changing climate patterns.

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.
