I am heading up the Dalton Hwy in about a week to do some caribou hunting and fishing along the way. Any suggestions on fly patterns for Lake trout in Galbraith lake and/or Arctic Char in the Sag river? I know all those rivers have grayling and I know what patterns to bring for those. Mostly I would like to catch some of those sea run Char in the Sag. I have heard there are some bigguns in there. Last year I hooked into one using a sculpin, but it got off.
