Summary
Built in 2008 by the USDA NRCS, this flood risk reduction structure stands at a height of 30 feet and has a storage capacity of 97.8 acre-feet. With a low hazard potential and a moderate risk assessment rating, the dam serves multiple purposes including fire protection, stock pond, fish and wildlife habitat, and flood risk reduction.
Constructed with a stone core and resting on a soil foundation, East Yellow Creek A-58 spans 490 feet in length and covers an area of 8 acres. The dam's uncontrolled spillway is 20 feet wide, allowing for a maximum discharge of 171.5 cubic feet per second. Despite not having a formal condition assessment, the structure is currently rated as "Not Rated" and has not been assigned an Emergency Action Plan (EAP) or undergone regular inspections.
Located within the Rock Island District, East Yellow Creek A-58's risk management measures and emergency preparedness status remain unclear. However, with its strategic positioning and multi-purpose functionality, this dam plays a crucial role in safeguarding the surrounding area from flood events while also supporting local wildlife and water resource management efforts. For water resource and climate enthusiasts, this structure serves as a noteworthy example of responsible dam construction and management in the heart of Missouri.

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.
