Summary
Situated on the Hamilton Branch, this dam stands at 33 feet high with a capacity for 125 acre-feet of water storage. With a surface area of 6 acres and a drainage area of 220 acres, the dam plays a crucial role in fire protection, stock management, and enhancing fish and wildlife habitats in addition to flood control.
Despite its low hazard potential, East Yellow Creek H-27 has a moderate risk rating due to its age and lack of recent condition assessments. The dam features an uncontrolled spillway with a width of 30 feet and no outlet gates. While the structure has not been modified since its completion, regular inspections every five years help ensure its safety and functionality. With Sam Graves (R) representing the area in Congress, East Yellow Creek H-27 serves as a vital resource for water management and environmental conservation efforts in Linn County, Missouri.
In the realm of water resource and climate conservation, East Yellow Creek H-27 stands as a testament to the importance of sustainable infrastructure development. With its focus on flood risk reduction and multiple environmental purposes, this earth dam not only protects local communities from potential disasters but also contributes to the enhancement of aquatic ecosystems and wildlife habitats. As efforts continue to assess and manage the dam's risk factors, it remains a critical asset in the ongoing mission to promote water security and climate resilience in the region.

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.
