Early spring and summer on the Yellowstone can be very productive. Depending on the day and water temperatures, pre-runoff can be some of the best fishing of the year. Nymphing something big like a Zirdle Bug, Pat’s Rubber Legs, or Woolly Bugger followed up by a worm or smaller euro-style nymph will be the most consistent rig out there this time of the year. Don’t be afraid of smaller flashy streamers such as the Kreelex Minnow or a Sparkle Minnow this time of year either. On warmer overcast days fish will be willing to move to a bigger streamer like a Dragon or a Dungeon. Midges and smaller Mayflies can hatch on the warmer days too, so keep your eyes peeled for rising fish in the slow water close to the bank. The Mother's Day Caddis hatch has started on the Yellowstone, so be sure to bring some caddis patterns!
