Figure B3. Time/distance color maps showing modeled downstream thermal effects of dams on (A) the South Fork McKenzie and McKenzie Rivers, and (B) the Clackamas River, Oregon, June–October 2001 and April–October 2002. Temperature changes are the difference in the modeled 7dADM temperatures for Natural Thermal Potential conditions with upstream dams minus the modeled 7dADM temperatures without upstream dams. Blue River joins the McKenzie River at river mile 54.
