New Zealnd Mud Snails in Lower Chehalis River

It is being reported that New Zealand Mud Snails have been discovered in the Lower Chehalis River in Washington.  If you are fishing in this area, please inspect, clean, and dry your waders and boots before moving to fish in new drainages.  NZMS are visible to the naked eye, and a good brush and high pressure water (the jet setting on a garden hose attachment will work fine) will remove NZMS.  Here's a link to an article on the Chehalis.
