Summary
The primary purpose of the dam is flood risk reduction, with additional purposes including fire protection, stock or small fish pond, fish and wildlife pond. This structure stands at a height of 26 feet, with a hydraulic height of 26 feet and a structural height of 32 feet, offering a maximum storage capacity of 78.5 acre-feet and a normal storage capacity of 22.5 acre-feet.
Situated on TR-East Yellow Creek in Linn County, Missouri, East Yellow Creek A- 78a covers a surface area of 4 acres and serves a drainage area of 32 square miles. The dam features an uncontrolled spillway with a width of 20 feet and is classified as having a low hazard potential with a moderate risk assessment rating of 3. While the condition assessment of the dam is currently not rated, it is reassuring to note that the emergency action plan (EAP) status and risk management measures are in place to ensure the safety and integrity of the structure.
East Yellow Creek A- 78a is a vital asset in the region for flood risk reduction, showcasing the collaboration between local government and the USDA NRCS in safeguarding the community against potential disasters. With its strategic location and functional design, this dam serves as a cornerstone in water resource management, emphasizing the importance of proactive measures in maintaining the resilience of our infrastructure in the face of changing climatic conditions.

Dam Data Reference
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.
