Production note:

COSEWIC would like to acknowledge Allan B. Costello and Emily Rubidge for writing the status report on the westslope cutthroat trout (Oncorhynchus clarkii lewisi) (British Columbia population and Alberta population) in Canada, prepared under contract with Environment Canada, overseen and edited by Dr. Robert Campbell, Co-chair, Freshwater Fishes Species Specialist Subcommittee.

The status report to support the May 2005 COSEWIC assessments of the westslope cutthroat trout (Oncorhynchus clarkii lewisi) (Alberta population and British Columbia population) was not made available following the 2005 assessment.

In November 2006, COSEWIC reassessed the westslope cutthroat trout (Oncorhynchus clarkii lewisi) (Alberta population and British Columbia population).  The status report was then finalized following the COSEWIC 2006 reassessment .
