Summary
Constructed in 2002 by the USDA NRCS, this earth dam stands at a height of 28 feet with a hydraulic height of 26 feet, providing a storage capacity of 104 acre-feet. The primary purpose of the dam is flood risk reduction, with additional benefits for fire protection, stock, small fish ponds, and fish and wildlife habitats.
With a low hazard potential and moderate risk assessment, Upper Locust Creek L-210 plays a crucial role in managing water resources in the Sullivan County area. The dam has a normal storage capacity of 31.3 acre-feet and covers a surface area of 7 acres, serving a drainage area of 160 acres. Despite its uncontrolled spillway and outlet gates, the dam is closely monitored with a five-year inspection frequency to ensure its structural integrity and safety.
Managed by the Natural Resources Conservation Service, Upper Locust Creek L-210 is an essential infrastructure for water resource and climate enthusiasts interested in sustainable flood control measures in Missouri. With Congressman Sam Graves representing the area, the dam contributes to the overall environmental conservation efforts in the region, showcasing the collaborative efforts between local government and federal agencies in safeguarding communities from potential flooding events.

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.
