: Missouri River: One of our guides was on the river below Craig a few days ago and said the fishing was tough overall. Despite the warm snap, water temps on the Missouri right now are hovering right around 35 degrees. This is due to the cold lake water that isn't susceptible to the warm air temps. There are still plenty of fish to be caught here right now, but don't expect the fish to show an eagerness to move much. Nymphing deep with worms and small flashy nymphs will be a good place to start, and anything pink with a fire bead is worth a shot as well.
