The Fish and Location: Located on Neuquen Province near to Junin de los Andes, the Collon Cura River is originated from the union of the great Alumine and Chimehuin rivers. Trout are exceptional fighters, with fish averaging in the 14 to 20-inch range. During the Argentine autumn, fall browns can run up to 28 inches.
The River: The Collon Cura River is perhaps the most prolific trout fishery in all of Patagonia. Flows nearly 50 miles until reaching the Piedra del Águila Reservoir. The first stretch covers 9 miles and it is possible to float downstream during the day. To have access to the middle and lower sections, it is necessary to go on a 3 or 4 days expedition trip, because the river flows far away from any road.
Collón Cura is the most "guide-friendly" river since it offers numerous and diverse fishing options and can be fished both from the boat and by wading in the countless channels and pools. Streamer fishing is a productive way to fish the river especially true in January when the river is full of Pejerrey minnows. But fish will take big dries such as hoppers, stimulators and Chernobyl ants, as well as nymphs. Evening hatches are great and sometimes the fish even become selective and force us to match the hatches. Not only can one catch many fish but one can also expect to catch a monster brown, at any time. Usually we will find a good number of rainbows surface feeding in huge back eddies that won't hesitate to raise to a Parachute Adams or Big Attractors. If the inch worms are falling from the willows or the minnows are moving in the shallows fishing can turn crazy caching from 20 to 40 trout during a full float, which happens frequently!
