Summary
Built in 2000 by the USDA NRCS, this earth dam stands at 31 feet tall and has a storage capacity of 108 acre-feet. With a primary purpose of flood risk reduction, this dam also serves fire protection, stock, small fish pond, fish and wildlife pond purposes.
Situated on the TR-Locust Creek river, Upper Locust Creek W-55 has a low hazard potential and a moderate risk assessment rating. The dam is uncontrolled, with an uncontrolled spillway width of 30 feet. The structure spans 520 feet in length and covers a surface area of 2 acres. Despite its age, the dam's condition assessment is currently labeled as "not rated", and it is inspected every 5 years to ensure its safety and effectiveness in managing flood risks in the area.
Owned by the local government and situated within the Rock Island District, Upper Locust Creek W-55 plays a vital role in protecting the surrounding community from potential flooding events. With its strategic location and design, this dam serves as a crucial component in the overall water resource management and climate resilience 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.
