Summary
It is an earth dam with a buttress core type, standing at a height of 15 feet and offering a storage capacity of 50 acre-feet. The dam is regulated by the Mississippi Department of Environmental Quality and has a low hazard potential, with a moderate risk assessment rating of 3.
Located in Benton County, Mississippi, Cannon Lake Dam sits at coordinates 34.74078523° N, -89.14758045° W. The dam features an uncontrolled spillway type and does not have any associated locks or structures. While the dam's condition is currently not rated, it is subject to state inspections, permitting, and enforcement to ensure its safety and compliance with regulations.
For water resource and climate enthusiasts, Cannon Lake Dam provides an interesting case study in private dam ownership and management for recreational purposes. With its modest size and low hazard potential, the dam serves as a valuable asset for both local residents and visitors seeking opportunities for outdoor activities like fishing, boating, and wildlife viewing. As climate change continues to impact water resources, understanding the role of dams like Cannon Lake in balancing conservation and recreation becomes increasingly crucial for sustainable water management practices.

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.
