Anywhere there is any chance that carp could get into salmon waters the wdfw will not put them there. Swofford spills right into Riffe, So if they do do something about the weeds it will be chemical as usual.

Also, I am not a fan of Grass carp either. Duck lake and Silver lake were ruined because of them stinky terds. Sure the fishing gets better at first then it takes a nose dive.
