Summary

Louis County, Minnesota, is a state-regulated water management area with a low hazard potential and satisfactory condition assessment. Built in 1978, this Earth-type dam stands at a height of 6 feet and has a maximum storage capacity of 3500 acre-feet. With a normal storage capacity of 2600 acre-feet and a surface area of 600 acres, Canosia Wma 6 plays a crucial role in managing water resources in the region.

The dam is situated on the Cloquet River-Trout Lake system and is owned and regulated by the Minnesota Department of Natural Resources - Ecological and Water Resources division. The primary purpose of Canosia Wma 6 is listed as "Other," indicating its multi-faceted role in water resource management. With a drainage area of 3.9 square miles and a maximum discharge capacity of 165 cfs, the dam serves as a key infrastructure for flood control and water supply management in the area.

Despite its relatively low hazard potential, Canosia Wma 6 undergoes regular inspections and enforcement measures to ensure its structural integrity and functionality. The dam's last inspection was conducted in August 2013, with a scheduled inspection frequency of every 8 years. With its strategic location and vital role in water management, Canosia Wma 6 stands as a testament to responsible water resource stewardship in the state of Minnesota.

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.
