Conditions have improved across the Park to the point that you can fish your river of choice. Everthing in the northwest corner is back to a great green color. There are Western Sedge Caddis beginning to hatch on all the rivers. The Salmon Flies have made it into the Grand Canyon of the Yellowstone. On the Lamar an olive stonefly was working better since the big bugs were yet to fly up this river. On the Lamar, Slough and Soda Butte you can hook into a lot more fish with a bugger or leech pattern. The dry fly action is just beginning but it will increase fast. The very upper section of the Yellowstone River will open next Sunday, the timing of the bugs getting through the canyon and past both falls may work out just right for the opener. The west side of the Park has shifted into PMD season and evening caddis. Stimulators are a good match now for a double fly rig.
