River X - Amazon Basin

Sweetwater is always looking for new, unexplored fisheries in the seemingly, endlessly vast Amazon Basin. We have been operating in the Amazon since 1992. During our years in the Amazon, we have been continuously searching for a clear water, white sand river that offers high quality sight fishing for Peacock Bass during the winter months of January, February, and March. This quest has inspired us to form a new mobile peacock bass operation where anglers can accompany us as we search for the next great Peacock Bass river.

The River X operation is a general name for our new mobile camps in the Amazon. This mobility allows us to move the boats to where the fish are and insure that there is always plenty of water to fish.


We are operating two different rivers located in the Brazilian state of Roraima on tributaries of the Branco River.. Both rivers have been selected for their water clarity and the quality of their fly-fishing opportunities.

The fisheries revolve around the lagoons, inland lakes and river channel. Butterfly peacocks are numerous and take poppers and streamers greedily. These fish fight hard and jump often.


River channel fishing is what makes these systems so special. The smaller peacocks are in the shallow water and respond well to any quickly stripped baitfish pattern. The Temensis and Spotted peacocks roam throughout the rivers in search of food. If they are actively eating(there is rarely any question as the water is exploding with colorful baitfish), any cast will do. In other cases, singles or doubles are spooky and require good casts. These are exciting shots as in most cases you can see the fish coming from a long ways.

In addition to the fishing, you will see remarkable birdlife and wildife on these rivers. This past year, we watched flocks of macaws fly noisily across the river, toucan fly furtively across a lagoon, and, most impressively, a jaguar hunt and eat a capybara. If the fishing ever slows down, you will be able to experience the biological diversity that still exists in pristine portions of rain forest.


The River X is a backcountry adventure with camps set up on sand bars in air conditioned, tented barges that move up and down the river as needed. It is a great way to experience the Amazon and to access the pristine rivers that provide some of the best Peacock Bass fly-fishing available anywhere. We hope you will join us.
