Trout Regulations
Rainbow Trout, Cutthroat
& Bull Trout
Bull, rainbow and cutthroat trout
are native to Washington waters.
Bull trout are listed as threatened
under the Endangered Species
Act. Bull, rainbow and cutthroat
trout look very much alike and
often live in the same waters.
Rainbow and cutthroat trout may
be harvested in most waters, but
harvesting or targeting bull trout is
illegal in the Lewis River basin.
Here is how you can tell them
apart. Rainbow and cutthroat
trout have distinct black spotting
on the dorsal fin, while bull trout
have no distinct spotting.
So remember, for the Lewis River,
tributaries and reservoirs:
Rainbow Trout
Oncorhychus mykiss
Bull Trout
Salvelinus confluentus
No Black, put it back!
