Summary

Louis County, Minnesota, is a state-regulated water management area situated along the Cloquet River-TR. The dam, completed in 1978, serves as an Earth-type structure with a height of 14 feet and a storage capacity of 3500 acre-feet. With a low hazard potential and satisfactory condition assessment, the dam poses no immediate threat to the surrounding area.

The primary purpose of Canosia Wma is listed as "Other," with a focus on water resource management and conservation efforts. The dam's controlled spillway type and very high risk assessment rating indicate the importance of effective risk management measures in place. Despite being last inspected in 2013, the dam's regular inspection frequency of 8 years ensures ongoing monitoring of its structural integrity and functionality.

Water resource and climate enthusiasts interested in Canosia Wma will find a unique blend of environmental stewardship and flood control in this state-regulated area. With its Earth-type dam and expansive storage capacity, Canosia Wma plays a crucial role in managing water flow along the Cloquet River-TR. The dam's location in a high-risk area underscores the need for continuous monitoring and risk management to ensure the safety of surrounding communities and the preservation of natural habitats.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
