Summary
The primary purpose of this dam is flood risk reduction along the New Boston Branch river. With a height of 25 feet and a length of 520 feet, East Yellow Creek H- 30 has a storage capacity of 187 acre-feet and serves a drainage area of 140 acres.
This low-hazard dam has a moderate risk assessment score of 3 and is currently not rated for condition assessment. Despite this, the dam has not been inspected recently, and there is no established inspection frequency. The spillway type is uncontrolled with a width of 30 feet, and there are no outlet gates associated with the structure. While the dam has not been modified in recent years, it remains an essential component of flood risk management in the area.
Overall, East Yellow Creek H- 30 plays a crucial role in mitigating flood risks in Linn County, Missouri, by providing protection along the New Boston Branch river. With a storage capacity of 187 acre-feet and a moderate risk assessment, this earth dam serves as a vital infrastructure for local government flood risk reduction efforts. Going forward, regular inspections and maintenance will be essential to ensure the continued effectiveness of East Yellow Creek H- 30 in protecting the surrounding community from potential flooding events.

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.
