Today the Mud Snail is found in fisheries across the western United States, in Idaho, Montana, Wyoming, Oregon and California and is having impacts on populations of Pacific salmon, cutthroat, redband, rainbow and bull trout.

In order to prevent the further spread of these invaders, it is up to each and every angler to be responsible and inspect, clean and dry their gear before traveling between fisheries.
