Summary
Built in 1977 by the USDA NRCS, this earth dam stands at a height of 57 feet and stretches 900 feet in length. It serves the primary purpose of flood risk reduction along Bryant's Creek, with a storage capacity of 2,380 acre-feet and a normal storage level of 158 acre-feet.
Managed by the local government, this dam is state-regulated and inspected regularly to ensure its satisfactory condition. With a high hazard potential and moderate risk assessment rating, the dam is equipped with an uncontrolled spillway and slide gates for outlet control. Despite its age, Clarence Cannon #15 continues to play a crucial role in protecting the surrounding area from flooding events, showcasing the importance of proper water resource management in the face of changing climate patterns.
As part of the Dam and Reservoir Safety Program in Missouri, Clarence Cannon #15 exemplifies the collaborative efforts between federal and state agencies to safeguard communities and infrastructure from potential water-related disasters. With a history of effective risk management measures and adherence to safety guidelines, this dam stands as a testament to the resilience of water resource systems in adapting to evolving environmental challenges. For water resource and climate enthusiasts, Clarence Cannon #15 offers a compelling case study on the intersection of engineering, policy, and environmental stewardship in ensuring the sustainability of our water infrastructure.

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.
