Summary
Constructed in 2005 by the Natural Resources Conservation Service, this earth dam stands at 28 feet tall and stretches 490 feet in length, with a capacity to hold 86.5 acre-feet of water. Serving multiple purposes including fire protection and wildlife habitat enhancement, the dam plays a crucial role in managing the water resources of the TR-Locust Creek watershed.
The dam's low hazard potential and moderate risk assessment make it a key asset in the area's water resource management strategy. With an uncontrolled spillway and outlet gates, the structure is designed to handle maximum discharges of up to 123.3 cubic feet per second. Despite its importance, the condition assessment for Upper Locust Creek W-140 is currently listed as "Not Rated," highlighting the need for regular inspections and maintenance to ensure its long-term functionality and effectiveness in flood risk reduction.
Located within the Rock Island District and under the jurisdiction of the state of Missouri, Upper Locust Creek W-140 stands as a testament to the collaborative efforts between local government and federal agencies in safeguarding communities against the impacts of extreme weather events. For water resource and climate enthusiasts, this dam serves as a prime example of sustainable infrastructure designed to mitigate flood risks while also enhancing the overall environmental quality of 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.
