Summary
Built in 2007 by the USDA NRCS, this earth dam stands at 24.8 feet high and spans 520 feet in length. With a storage capacity of 111.6 acre-feet, it serves multiple purposes including fire protection, stock or small fish pond, fish and wildlife pond, and flood risk reduction. The dam is situated on TR-East Yellow Creek and is under the jurisdiction of the Rock Island District of the US Army Corps of Engineers.
This low hazard potential structure has a moderate risk assessment rating and is currently in a not rated condition assessment status. The dam features an uncontrolled spillway with a width of 20 feet and outlet gates that are also uncontrolled. With a drainage area of 275.2 square miles, East Yellow Creek A-42 plays a crucial role in managing water resources in the region. While it has not been inspected recently, the structure is designed to mitigate flood risks and protect the surrounding area from potential inundation.
For water resource and climate enthusiasts, East Yellow Creek A-42 offers a fascinating example of sustainable water management practices in action. With its strategic location and design, this dam not only provides flood protection but also supports environmental conservation efforts by creating habitats for various wildlife species. As a key infrastructure asset in Sullivan County, Missouri, this structure showcases the importance of responsible water resource management and the integration of multiple purposes in dam construction.

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.
