: Missouri River: The Tricos are in thick right now. Delicate presentations and not lining fish are key. Trout have been hitting flies the moment they land on the water so be ready! The 18" average browns and rainbows are definitely picky from about 2-6:30 PM under bright skies and heat, but nymphs still get them during the dry doldrums. Cooler temperatures have prompted better fishing and crowds are diminishing so the MO is an awesome option right now. Fish are starting to become more wary of sloppy drifts and bigger tippet sizes. So down sizing your tippet to 5 or 6X and presenting delicate drifts would be a good idea for the picky fish. As with most other rivers fishing in the morning and evening has been best.
