Summary
Completed in 1962, this earth dam stands at a height of 30 feet with a length of 400 feet, offering a storage capacity of 51 acre-feet and a normal storage of 14 acre-feet. With a low hazard potential and a moderate risk assessment, this dam plays a crucial role in managing the flow of water and mitigating potential risks in the area.
The 102 River Tributaries Dam 9 is owned by the local government and falls under the jurisdiction of the state of Missouri. With its uncontrolled spillway type and stone core, this structure has been serving its primary purpose of grade stabilization effectively over the years. Despite not being state regulated, inspected, or enforced, this dam stands as a testament to the collaborative efforts between federal and local agencies in ensuring the safety and sustainability of water resources in the region.
As a key component of the water management infrastructure in the Kansas City District, the 102 River Tributaries Dam 9 stands as a testament to the importance of proactive measures in safeguarding against potential risks and ensuring the efficient utilization of water resources. Its strategic location in ARKOE, Missouri, highlights its significance in maintaining the ecological balance and enhancing the resilience of the local ecosystem 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.
