Summary
Built in 1978 by the USDA NRCS, this earth dam stands at a height of 29 feet and spans 1,066 feet in length, with a storage capacity of 213 acre-feet. Despite being categorized as having a high risk potential, the dam is currently deemed to be in a not rated condition, highlighting the importance of regular inspections and maintenance.
With no spillway and limited structural features, Cannon Lake Dam serves as a vital water resource for the surrounding area and supports various ecological functions. It is interesting to note that the dam is not regulated by the state and is not under the jurisdiction of any state agency. Despite its private ownership, the dam plays a crucial role in sustaining the local ecosystem and providing water for recreational activities, highlighting the intersection of water resource management and climate resilience in the region.
As a key component of the local landscape, Cannon Lake Dam stands as a testament to the ongoing challenges and opportunities in managing water resources in the face of changing climate conditions. With its historical significance and ecological importance, this dam serves as a focal point for water resource and climate enthusiasts seeking to understand the intricate balance between human intervention and natural systems.

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.
