Summary
Built in 2006 by the USDA NRCS, this earth dam stands at a height of 28.3 feet and has a hydraulic height of 26 feet. With a storage capacity of 173.6 acre-feet and a drainage area of 403.2 acres, the dam serves its primary purpose effectively in mitigating flood risks in the area.
The dam features an uncontrolled spillway with a width of 40 feet and outlet gates that are also uncontrolled. Its hazard potential is rated as low, with a moderate risk assessment score of 3. Though the condition assessment is not rated, the structure is regularly inspected to ensure its integrity. While no emergency action plan is mentioned, the dam meets guidelines for risk management measures, providing a sense of security for the surrounding community in the event of a flood event.
Overall, East Yellow Creek W- 52 serves as a vital infrastructure for flood risk reduction in the area, designed and constructed by the Natural Resources Conservation Service. With a focus on safety and efficient water resource management, this dam plays a crucial role in protecting the residents and land along TR-WINIGAN CREEK in Linn, Missouri, demonstrating the importance of sustainable water resource practices in mitigating the impacts of climate change.

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.
