: Missouri River: This week is going to be warmer than the last few. e may even see the mercury creep near 40 this week. The fish have move into the slow soft water to spend the winter. Look for where seam lines and feeding lanes converge with slow water. I fished during the cold Christmas weekend and it helped to keep the car close. When the cold becomes too much you can head back and blast your heater. Pink Scuds and Sow bugs have been two very hot flies. Some fish are starting to eat midges on the surface. The dry fly fishing will pick up towards the end of February.
