Create CHaMP map

Start by looking at which watersheds we need polygon shapes for.

Watersheds with paired fish-habitat data:

          Watershed  n percent
             Entiat 61   18.6%
           John Day 75   22.9%
              Lemhi 34   10.4%
              Minam 20    6.1%
  South Fork Salmon 30    9.1%
 Upper Grande Ronde 86   26.2%
          Wenatchee 22    6.7%

Watersheds with CHaMP habitat data

          Watershed  n percent
             Entiat 89   16.8%
           John Day 80   15.1%
              Lemhi 30    5.7%
             Methow 45    8.5%
              Minam 20    3.8%
  South Fork Salmon 43    8.1%
           Tucannon 47    8.9%
 Upper Grande Ronde 87   16.4%
          Wenatchee 45    8.5%
        Yankee Fork 44    8.3%

Looks good. Let’s save the polygon sf to use later.

Now let’s make a map that we can import into the manuscript
