Summary
This earth dam stands at a height of 25 feet and has a hydraulic height of 22 feet, with a maximum storage capacity of 81 acre-feet. The primary purpose of the dam is flood risk reduction, but it also serves as a fire protection structure and provides benefits for stock, fish and wildlife ponds.
With a normal storage capacity of 23.3 acre-feet and a surface area of 3 acres, East Yellow Creek A-80 plays a crucial role in managing water resources in the region. The dam has a relatively low hazard potential and has not been rated for its condition assessment. However, it has been inspected periodically, with the last inspection conducted in November 2004. The dam has an uncontrolled spillway type with a width of 20 feet, and the maximum discharge capacity is 129.8 cubic feet per second.
Overall, East Yellow Creek A-80 contributes to the sustainable management of water resources and serves as a vital infrastructure for flood risk reduction in the area. With its strategic location and design, the dam plays a key role in protecting the surrounding community from potential flooding events, while also providing additional benefits for wildlife and fire protection. Monitoring and maintenance efforts are essential to ensure the continued effectiveness and safety of this important water resource structure.

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.
