Since a lot of fishing reports lately have been telling people to go to the Yellowstone, the Madison has had significantly less pressure than normal and the fishing has actually been quite good! Nymphs and streamers are still your best bet if you are looking for big browns, but there are plenty of fat 16 inch rainbows up eating dries on the edges and behind rocks in the middle of the river. Try a mix of small (size 12-14) hoppers, crickets, flying ants, and attractor baetis patterns. For nymphs, rubberlegs, beadheads, lightning bugs, copper johns, and baetis nymphs. For streamers try any color you like but black and olive have been popular. This time of year fish tend to get nippy, so you might want to fish an articulated fly or a streamer with a stinger. If you have the luxury of picking your day, overcast and nasty have been better for the big ones. Be sure to bring your camera, the browns are really starting to look sharp!
