Summary
This earth dam stands at a height of 34 feet and has a length of 790 feet, with a storage capacity of 300 acre-feet and a drainage area of 192 square miles. Despite its low hazard potential, the dam is considered to have a moderate risk level, emphasizing the importance of proper risk management measures.
Owned by the local government, Clarence Cannon Dam 9 is designed to protect the surrounding area from potential flooding events, with a primary purpose of flood risk reduction. The dam's spillway, measuring 50 feet in width, is uncontrolled, and there are no outlet gates associated with the structure. Although the dam's condition assessment is currently not rated, its operational status and risk level underscore the need for ongoing monitoring and maintenance to ensure its continued effectiveness in safeguarding the community.
As part of the Kansas City District, Clarence Cannon Memorial Watershed Dam 9 plays a crucial role in water resource management and climate resilience efforts in the region. With its strategic location and design by the Natural Resources Conservation Service, the dam serves as a key infrastructure asset for mitigating flood risks and protecting the surrounding environment. As water resource and climate enthusiasts, understanding the significance of structures like Clarence Cannon Dam 9 highlights the importance of sustainable water management practices to build resilience against changing weather patterns and potential natural disasters.

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.
