Summary
This earth dam, standing at a height of 25 feet and a length of 415 feet, has a storage capacity of 66 acre-feet and covers a surface area of 15 acres. With a low hazard potential and a moderate risk assessment rating of 3, the dam plays a crucial role in managing water flow and preventing debris from causing potential hazards downstream.
Despite not being regulated or inspected by the state, Clarence Cannon Dam 34 continues to fulfill its primary purpose of debris control efficiently. The uncontrolled spillway, with a width of 30 feet, can handle a maximum discharge of 370 cubic feet per second. The dam's condition assessment is currently not rated, and emergency action plans are yet to be prepared. Even though the dam does not have outlet gates, its stone core and soil foundation provide structural stability, ensuring its reliability in managing water resources and protecting the surrounding area from flood risks.
In the picturesque setting of Elsberry, Missouri, Clarence Cannon Memorial Watershed Dam 34 stands as a testament to efficient water resource management and conservation efforts. With its strategic location and design by the Natural Resources Conservation Service, this earth dam continues to play a crucial role in maintaining water quality and preventing debris-related hazards in the region. As a valuable asset in the local government's infrastructure, the dam's low hazard potential and moderate risk assessment underscore its importance in safeguarding the community and environment from potential water-related risks.

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.
