Summary
This earth dam stands at 25 feet high and has a storage capacity of 80.4 acre-feet, serving multiple purposes including fire protection, stock, and small fish ponds in addition to flood risk reduction. The dam's spillway, with a width of 30 feet, is uncontrolled, and the structure is deemed to have a low hazard potential and moderate risk assessment.
Managed by the local government, this dam on the TR-Locust Creek is situated in an area represented by Sam Graves (R) and falls under the jurisdiction of the Rock Island District. With a drainage area of 130 square miles and a normal storage capacity of 23.8 acre-feet, the dam plays a crucial role in mitigating flood risks in the region. Despite being unregulated by the state, the structure is subject to regular inspections every 5 years, with its condition currently not rated.
Water resource and climate enthusiasts will appreciate the engineering prowess behind the Upper Locust Creek W-182 dam, which not only serves as a flood risk reduction measure but also supports various ecological functions. With its strategic placement and design features, this structure exemplifies the importance of sustainable water management practices in safeguarding communities and ecosystems against the impacts of climate change. As a key component of the local water infrastructure, this dam stands as a testament to the collaborative efforts of government agencies and conservationists in ensuring water security for 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.
