"The Wedding of The Waters"

Wind River Canyon Fly Fishing

Big Horn River Fly Fishing aka “Wedding of the Waters” comes with history and excitement. While most people relate the Big Horn to the famous stretch of water outside of Fort Smith, Montana, Wyoming natives think otherwise. Although we may be biased, we believe our stretch of the Big Horn River gives the Montana stretch a run for its money.

Blue Ribbon Fishery

The Bighorn is another famed Blue Ribbon fishery that sits nearest to the town of Thermopolis, Wyoming. Thermopolis is located about two hours North West of Casper. This tailwater fishery is stabilized by the dam and rich in nutrients. These conditions make for a healthy fish population. The Bighorn is a tributary of the Yellowstone River, and is completely separate from the North Platte drainage system. The upper most portion of the Big Horn is called the Wind River. This is the name of the river as it flows through the reservation. Once the river hits Boysen Dam, it is called the Big Horn. The area where the Wind River turns to the Big Horn River is fittingly coined as “The  Wedding of the Waters”.

3,000 Fish Per Mile

Cut throats, Rainbows, Brown Trout

The Big Horn boasts a fish count around 3,000 per river mile. The stretch consists of mostly Rainbows, Browns, and Cutthroats with an average trout size of 16 to 18 inches. The Big Horn has a multitude of protein staples in its waters including an abundance of scuds and leeches. This is due to the high alkaline content in the water that comes from the local hot springs. These protein sources coupled with prolific hatches are what makes the trout in this section eager to eat. Whether you prefer to fish nymph rigs, dry flies, or chuck streamers, you will find any fashion is productive on the Big Horn.


Hot Springs State Park

Another reason that the Bighorn is different from any other river in the area is that it flows through Hot Springs State Park. Is that it flows through Hot Springs State Park. Cold day on the water? Not a problem on the Bighorn. Just hop out of the boat and right into one of the natural hot springs.

My family and I have been customers of Crazy Rainbow for years. It would take us some time to try and calculate how many fish we have caught with them over the years.

BEYOND EXPECTATIONS! I spent a week in July fishing with Ugly Bug guides Justin, Troy, and Addie (also at the shop) on the North Platte catching rainbows, cutthroats, and browns. I have fly fished most of my adult years, and this was by far the best trip of my life.

So, between Eduardo Barrueto and Andi Manstein we decided to go forward and start setting up this fantastic dream, that we called The River of Dreams.

Agua Negra Camp

Travel to the Agua Negra Camp, which is a remote yet luxurious tent camp/lodge perched on a bluff overlooking the Secure River. Roughly 100 yards away is the small native village of Agua Negra, which makes this camp by far the most culturally rich of the Tsimane experiences. Here anglers will enjoy very comfortable double occupancy safari tents with attached baths as well as the comfort of the main lodge building where drinks and meals are served. The fishing will be done on the main Secure as well as on the Agua Negra River. The Agua Negra is smaller and offers not only big dorado but the region’s most forgiving terrain as well as the greatest diversity of species including large pacu, pira pita and the elusive striped catfish known as surubi.
