Things have been looking a little icy on the Lower Madison lately. Be sure to bring a 4-wheel drive vehicle with decent clearance if you are heading to either side of Bear Trap canyon. With these colder temperatures nymphing is going to be more productive than swinging or fishing streamers. As pretty as winter fishing can be it may not be worth battling the elements right now. Definitely no need to drive down low as the ice shelves are thick and dangerous…
