Climate Stress Summary By Subwatershed. This layer describes the relative magnitude of projected changes across watersheds. Seven climate stress variables were summarized by subwatershed. Thresholds were then assigned to each of the variables, with the variables given a value of 1 if they passed the threshold, and 0 otherwise: Absolute change in length-weighted number of winter floods > 4; Percent change in length-weighted 25-year flood > 25; Percent change in length-weighted decadal low flow > 25; Percent change in snow water equivalent > 25; Percent change in snow residence time > 25; Percent change in 90th percentile number of summer dry days > 25; Historical (1993-2011) stream temperature > 18 °C (i.e., above 20 °C with a 2 °C temperature increase); These values were summed, then divided by the number of variables with data in that subwatershed, to identify the percentage of variables with projected changes over the thresholds. Low: < 25%; Medium: >= 25, < 50%; High: >50%; All future data are for the time period 2070-2099, using RCP 8.5 (https://www.globalchange.gov/browse/multimedia/emissions-concentrations-and-temperature-projections), The input layers used for the summaries include the Streamflow Metrics dataset (https://storymaps.arcgis.com/stories/6a6be7d624db41638a24b659305af522), National Forest Climate Change Maps (https://www.fs.usda.gov/rm/boise/AWAE/projects/national-forest-climate-change-maps.html), and the NorWeST Stream Temperature dataset (https://www.fs.usda.gov/rm/boise/AWAE/projects/NorWeST.html). Scenario = RCP 8.5; incorporates data from several data sources. Climate variables (snow-water equivalent, snow residence time, and summer dry days) use the average of 20 global climate models (bcc-csm1-1, bcc-csm1-1-m, BNU-ESM, CanESM2, CCSM4, CNRM-CM5, CSIRO-Mk3-6-0, GFDL-ESM2G, GFDL-ESM2M, HadGEM2-CC365, HadGEM2-ES365, inmcm4 , IPSL-CM5A-LR, IPSL-CM5A-MR, IPSL-CM5B-LR, MIROC5, MIROC-ESM, MIROC-ESM-CHEM, MRI-CGCM3, NorESM1-M). Streamflow variables (winter floods, 25-year floods, and decadal low flows) use the average of 5 climate models used in RPA Assessment: Least Warm-MRI-CGCM3; Hot-HadGEM2-ES; Dry-IPSL-CM5A-MR; Wet-CNRM-CM5; Middle-NorESM1-M. Stream temperature adds 2 degrees Celsius to historical (1993\u20132011) temperatures. <\/span><\/p>
