Figure 6.

Stream segments with at least 1°C temperature decline when (A) comparing current and restored shade condition temperatures for the 2000s climate. Black lines in part A indicate the Columbia River mainstem and some of the major tributaries for reference to Figures 1 and 2. Density distribution plots (B) show the range in size of streams (as bankfull width) across the entire study system (All reaches) and the reaches that cool by 1°C or more in part A. A scatter plot (C) compares the difference in shade percent between the restored and current shade conditions as bankfull width (note log scale) changes across all study reaches. A linear relationship (D) between the percent shade difference and temperature difference for the reaches cooling by 1°C or more.
