Summary
The primary purpose of this dam is flood risk reduction along the TR-East Yellow Creek. Standing at a height of 25.3 feet with a structural height of 32 feet, this dam has a NID storage capacity of 145.4 acre-feet and a normal storage capacity of 45 acre-feet, serving a drainage area of 108.8 square miles.
With a hazard potential rated as low and a moderate risk assessment score of 3, East Yellow Creek B-45 plays a vital role in mitigating flood risks in the area. The dam has an uncontrolled spillway type with a width of 30 feet and outlet gates also uncontrolled. Despite not being state-regulated or inspected, the dam remains in good condition and continues to provide essential flood protection for the surrounding community.
Overall, East Yellow Creek B-45 is a crucial infrastructure for flood risk reduction in Linn, Missouri, with a solid design by the USDA NRCS. Its low hazard potential, moderate risk assessment, and uncontrolled spillway system make it a reliable structure for managing water resources in the area. As it continues to operate effectively since its completion in 2006, East Yellow Creek B-45 stands as a testament to the importance of well-designed dams in climate resilience and water management.

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.
