Can anyone confirm a whitefish behavior in rivers. I've heard that
whitefish
will roll small rocks over using their snounts in an effort to dislodge
nymphs. Some of have said this sometimes the flashes you'll see in a
stream
when the whitefish are rolling over rocks.

This sounds reasonable... I have caught whitefish on the surface using dry
flies. They will pod up with rising trout and feed the same as Rainbow,
Cutthroat and Browns on the surface. It's near impossible to tell if you
have a trout or whitefish by the take. I have seen this on Kelly Creek and
the Bitterroot.
