Yellowstone Park 9-16-17

Big news here is that Hebgen Lake browns and rainbows are beginning to move into the Madison River above. So streamer patterns presented on sink tip lines will become increasingly effective here as the season advances to the first weekend in November when the Park fishing season closes.  The other happening is that the Firehole River is cooling off to the point that resident trout are not in survival danger on being caught and released.  Look for good BWO and caddis activities to attract fish here. The Gibbon River along with Grebe, Wolf, and Ice Lakes have been chemically treated to remove resident rainbow trout and grayling which are to be replaced with grayling themselves. Thus reliable grayling fishing in the park is reduced to Cascade Lake in the Yellowstone River drainage.
