Best Fishing Techniques
Different fishing seasons call for different fishing tactics. Here is a breakdown:
Spring: Looking to catch a 20+ inch trout? Break out the streamers! When the river begins to thaw, and the water turns from murky to green, it’s time to throw streamers. The best retrieve for a big hit, is a strip and pause. Slow short strips followed by a few second pause seem to work best.
Summer: Downsize your tackle. Aside from keeping a variety of tippet sizes, you’ll want to downsize your tackle as the summer season peaks. The fish tend to be most skittish, so a thinner tippet and longer leader (11ft) is preferred. Throwing smaller sized bugs will up your chance of getting fish to bite.
Fall: Fall is the best time to land a trophy brown trout. Egg pattern flies are a safe bet, due to the large amount of eggs found in the river from October through November. They provide a high amount of nutrients to the fish. Because trout are spawning this time of year, they can be particularly aggressive. Throwing a large streamer is a safe bet to entice a strike from a trophy brown.
The Yellowstone River is a truly unique river that is the largest in the lower 48. Its nearly 700 miles of river gives way to some of the greatest trout fishing in the United States. Pack up your fly gear and head out west, Yellowstone has some big fish to be caught!
