Yellowstone National Park

Lewis, Shoshone and Yellowstone Lakes are ice free.  Yellowstone boating permits and a passed Aquatic Invasive Species (AIS) inspection obtained before boating are required on any still water in the park. Campsites on all these lakes are subject to a reservation system meaning each site is reserved for occupation by the group that has signed up for it first. Successful fishing by wading shorelines to present streamer and woolly bugger patterns will soon diminish as water warms up. Boating on Lewis and Shoshone can be the best way to action. Concentrate casting streamer and wooly bugger patterns toward submerged weed beds.  Fishing on the Firehole River remains the best dry fly location with white miller, other caddis, BWO life cycle and soft hackled patterns providing action for fly fishers with the afternoon caddis activity adding to the top water excellent fishing. Caddis activity is also good on the Gibbon River below the falls. Northeast corner streams are still high and discolored. The Gallatin River is running high and discolored with run off. Park fishing licenses are available through the park web site, and visitor and ranger station offices within.
