This data set combines USGS Hydrologic Units (Subbasins = 5th field HUC) with data on the change in April to September Run off from 1950 to a 2 degree C increase in temperature. Data from: Alan Hamlet, University of Washington.
Data comes from the Parameter-elevation Regressions on Independent Slopes Model (PRISM). March, April, and May values were averaged for the years 1992 to 2008. Temperatures are in degrees C.
This data set combines USGS Hydrologic Units (Subbasins = 5th field HUC) with data on the proportion of precipitation that falls as snow in 1950.
The change in summer run off (April-September) by watershed in Western Washington. Data are expressed as a ratio of 2003 value / 1913 value). Data are from Alan Hamlet, University of Washington
Data comes from the Parameter-elevation Regressions on Independent Slopes Model (PRISM). July-October values were averaged for the years 1992 to 2008. Temperatures are in degrees C.
Data comes from the Parameter-elevation Regressions on Independent Slopes Model (PRISM). March, April, and May values were averaged for the years 1992 to 2008. Temperatures are in degrees C. Since the defined season (Dec - Feb) crosses years, this map actually starts with Dec 1991 and ends with Feb 2008.
This layer provides the location of stream gages in Western Washington and values for Maximum recorded historical temperature and future modeled temperature from the composite climate model with the A2b emissions scenario.
