Unlike most North American rivers, the Manso flows freely from its source at the glaciers on spectacular Mont Tronador. After being cleared of glacial silt by a string of lakes, the river becomes a crystal clear, turquoise, Patagonian river. We regularly fish two to three separate stretches on the riverutilizing drift boats and rubber rafts to travel and fish on the river, stopping where it is practical to wade fish. Each of these stretches has its own character and they range from smooth, quiet runs through medium size lakes to brawling whitewater that requires a portage or two to navigate. Yet all the water is productive with wild browns and rainbows throughout that range from 10-24 inches. Fish in the river average 14-16 inches, with larger fish passing through the river from one of the feeder lakes.
At Lago Hess the river forms a series of serpentine, grass-lined channels that provide outstanding dry fly fishing in the evenings. With majestic snow-capped Tronador in the background, fishing “The Channels” is a great way to cap a full day on the river. The evening time provides some of the best hatches, and provides for countless rising targets. Because of its proximity to Bariloche it makes for a great day trip from the town, or if more time is wanted, we would recommend staying at the Rio Manso Lodge. From there we can access all of the sections of the river, and a couple nearby lakes.
