Summary
It serves the primary purpose of flood risk reduction along the TR-East Yellow river or stream. With a height of 18 feet and a hydraulic height of 15 feet, the dam spans 465 feet in length and has a storage capacity of 97 acre-feet.
Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition assessment. It features an uncontrolled spillway with a width of 20 feet and no outlet gates. The surrounding area covers 3 acres with a drainage area of 57.6 square miles. Although it has not been inspected since its completion in 2001, the dam is designed to manage a maximum discharge of 126 cubic feet per second.
East Yellow Creek B-41 stands as a vital infrastructure for flood control in the region, showcasing the collaboration between local government and federal agencies to mitigate potential risks and protect the community from flooding events. Its strategic location and design contribute to the overall water resource management efforts in Missouri, marking it as a significant asset for water resource and climate enthusiasts to appreciate and study further.

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.
