An addendum has been added to the end of the document that reviews the recent study, The Mediated Associations and Preferences of Native Bull Trout and Rainbow Trout With Respect to Maximum Water Temperature, its Measurements Standards, and Habitat. This new study was brought to our attention after completion of the Technical Appendix. To ensure all key data was considered, the study was reviewed for its relevance to the recently developed British Columbia Water Quality Guideline for Temperature. The review concluded that no changes to the Guidelines were necessary.
