Summary
Designed by the USDA NRCS and completed in 2008, this earth dam stands at 33 feet high with a structural height of 42 feet. The dam boasts a normal storage capacity of 36.2 acre-feet and serves multiple purposes, including fire protection, stock or small fish ponds, fish and wildlife habitat, and flood risk reduction.
Situated on the TR-Locust Creek, this dam has a low hazard potential and is not currently rated for its condition. With a moderate risk assessment score of 3, Upper Locust Creek L-142 is managed by the Natural Resources Conservation Service and falls under the jurisdiction of the state of Missouri. The dam features an uncontrolled spillway with a width of 30 feet and an outlet gate system. Its location in Rock Island District and association with the primary purpose of flood risk reduction make it a crucial asset for water resource and climate enthusiasts interested in conservation efforts in the region.
Overall, Upper Locust Creek L-142 serves as a vital structure for managing flood risks and supporting various water-related activities in the area. With its strategic design and construction by the USDA NRCS, this dam stands as a testament to effective water resource management in Missouri. Its presence on the TR-Locust Creek not only helps protect the surrounding community from potential flooding but also contributes to the enhancement of wildlife habitats and overall environmental conservation efforts in the region.

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.
