Figure B2. Time/distance color maps showing modeled downstream thermal effects of dams on (A) the Middle Fork Willamette River, (B) the Coast Fork Willamette River, and (C) the Long Tom River, Oregon, June–October 2001 and April–October 2002. Temperature changes in this figure are the difference in the modeled 7dADM temperatures for Natural Thermal Potential conditions with upstream dams minus the modeled 7dADM temperatures without upstream dams.
