Fly anglers wait all year for the month of July. At this point of the year, everything necessary for a successful day on the water aligns and anglers find themselves consistently catching fish. Gone are the days of runoff, minimal hatches and unpredictable weather. The dry fly bite begins to heat up and anglers finally have an opportunity to show off their skills.

As you begin to plan your trips to the water, here is a list of seven rivers you should fish in the month of July.


1. Yellowstone River – A Fly Fisher’s Destination

If we’re being honest, the Yellowstone could be on the list of best rivers to fish for several months of the year. This massive body of water that flows through Montana and Wyoming has everything that an angler would want. In July, the water levels begin to decrease due to minimal runoff and its true colors begin to show. You’ll have access to pocket water, seams and pools.

Wade fishing starts to improve so all types of anglers are able to hit the water and see what they can find. The west is the place to be for fly fishing in July. Beautiful mountain views combined with quality fish puts a smile on every angler’s face.

In the Yellowstone, you’ll find rainbow, brook, brown and cutthroat trout. In July, you can start catching these on dry fly patterns, but streamer fishing also improves as the temperatures rise. The fish often dive deeper into the pools so a baitfish streamer near the bottom is always enticing.

Where to Fly Fish on the Yellowstone River

The Yellowstone river stretches over 692 miles so there are numerous places you can choose to fish it. Depending on the aesthetic you’re after, you can be a bit more picky. The portion between Gardiner and Carbella near Yellowstone National Park is a great option. The dry fly hatches during July are impressive and wade fishing isn’t too challenging. Work your way up from the Carbella access and see what you can find.

What to Pack for Fly Fishing in Alaska

Depending on the type of fishing you’re doing, you’ll need different equipment. If you’re targeting salmon, be sure to use an 8 or 9-weight switch rod. The trout can be targeted with a 7-weight, but it’s always smart to have too much power compared to not enough. For leader, you’ll want 0 or 1x salmon leader. These are a bit longer and have more power to handle the large fish.

Be sure to have enough flies packed as well as sinking tip line. Many of these fish peruse the bottom and want to feast on the eggs and flesh that are lower in the water column.

Waterproof is the name of the game in Alaska. You won’t regret the investment in quality rain gear. Check out this article for the best fishing hats to wear in the rain.
