Summary
Completed in 1962, this earth dam stands at a height of 33 feet and spans 420 feet in length, with a storage capacity of 93 acre-feet. Despite being unregulated by the state, this dam serves a critical purpose in managing water resources within the region, with a low hazard potential and a moderate risk assessment rating.
With a spillway width of 30 feet and a maximum discharge of 446 cubic feet per second, the 102 River Tributaries Dam 23 plays a key role in flood control and water management. The dam's stone core and soil foundation reinforce its structural integrity, while its uncontrolled spillway ensures effective water release during periods of high flow. Although not currently inspected or rated for condition assessment, this dam remains an essential component of the local water infrastructure, serving the community of ARKOE and surrounding areas.
As a Grade Stabilization structure owned by the Local Government, the 102 River Tributaries Dam 23 represents a collaborative effort between federal and state agencies to safeguard water resources in Missouri. While its emergency action plan and risk management measures may need further development, the dam's strategic location and design contribute to its overall effectiveness in mitigating flood risks and ensuring sustainable water utilization for the region's residents and ecosystems.

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.
