Climate data from NOAA/ NWS Co-op Network stations are complied in Table 3.5-1 and their locations are shown on Figure 3.5-3.  Figure 3.5-3 also shows precipitation contour data from the Spatial Climate Analysis Service (SCAS) at Oregon State University.  The Douglas Basin does not contain Evaporation Pan, AZMET or SNOTEL/Snowcourse stations.  More detailed information on climate in the planning area is found in Section 3.0.3.  A description of the climate data sources and methods is found in Volume 1, Appendix A.  For a link to the web site for each climate data source click its header.
