We are moving into late winter early spring here in Southern Montana and that means Yellowstone river will be picking up! If you hit it right you could have a stellar day! Indicator rigs can be effective especially on sunny day, try a bugger followed by your favorite midge pattern. Try stripping streamers on cloudy days and if you're more into dry fly fishing and see some noses throw baetis and midge cluster dries. Areas of the river with spring creek influence can be a great option right now as there will be warmer water pumping into the colder main river, giving the trout a comfortable place to pod up and look for food. If you plan to fish the Yellowstone, be sure to check FWP's Restrictions and Closures page for up-to-date information regarding closures.
