A while back Gregg Good gave us an updated list + shapefile of illinois’ impaired stream segments (303d list). I think we need to replace the “EPA impaired streams” layer with this more current list, especially on the Illinois site.  The only issue is I believe it has all the impaired waters, not just the ones that are impaired by something to do with nutrients… I cannot open GIS files to see if the database can be sorted/pared down to just nutrient-related impairments. … Is this something that can be turned into a spreadsheet that I can edit to remove the sites that have causes such as mercury or PCBs? After that, can we get it uploaded to the site?

(the file is in the box folder gltg-shared/GIS/Illinois CWA 303d)

Thanks-
