Yellowstone Park 8-10-13
Right now the Park is crowded with tourists. But good roadside fishing is possible. The Madison and Gibbon Rivers are warm enough to make for slow fishing except early in the day when tricos are beginning to show. Obsidian Creek is full of eager brookies, but a braggin’ fish would be around 12 inches. So use a lighth weight system. A more interesting location would be near the northeast part of the Park where trout in the Lamar River and Soda Butte Creek are responding well to grasshopper patterns. The same should be happening on Slough Creek’s meadows. Another possibility is the Gallatin River in the Park where evening caddis emergence can bring fish up.
