Summary
With a height of 22 feet and a length of 450 feet, this dam has a storage capacity of 121 acre-feet and serves as a critical infrastructure for managing water resources in the area. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition, and its emergency action plan remains unprepared.
The dam, which is owned by the local government, is designed to withstand the maximum discharge of 595 cubic feet per second and is equipped with an uncontrolled spillway with a width of 35 feet. Although there are no associated structures or outlet gates, the dam plays a vital role in controlling water flow and maintaining the stability of the surrounding area. With its location in the Kansas City District and under the jurisdiction of the state of Missouri, Tabo Creek Watershed Dam C-21 represents a crucial component of the region's water resource management infrastructure.
For water resource and climate enthusiasts, Tabo Creek Watershed Dam C-21 provides an intriguing case study of earth dam construction and management practices. As a grade stabilization structure with a stone core and soil foundation, this dam showcases the importance of strategic planning and monitoring in ensuring the safety and effectiveness of water management infrastructure. With its historical significance and ongoing role in the local ecosystem, Tabo Creek Watershed Dam C-21 stands as a testament to the intersection of engineering, environmental stewardship, and community resilience in the face of changing climate conditions.

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.
