Cabin and Beaver creeks are putting muddy run-off big time into Quake Lake and the Madison River just above it. So much of this stuff coming in that the Madison coming out of Quake Lake is also discolored. From Cabin Creek upstream to Hebgen Dam the river is in great shape, but there are more anglers there than resident trout. Remembering that this is opening weekend for Montana fishing general season, expect crowds just about anywhere . The Beaverhead River below Clark Canyon Dam remains in good shape with PM BWO and caddisfly activity bring responses.
