This sheet of water has shown a very curious behavior. Many years ago, the locals considered it a very good place to fish. Nowadays it is thought of as a low yield area for fishing. The causes of this situation seem to be the urban development of its northern tip, the strong impact on Gutiérrez stream which joins it to Lake Nahuel Huapi and the changes in certain natural spawning areas like the Pescadero stream.
The fact is that ichthyology research carried out by Universidad del Comahue, with headquarters in San Carlos de Bariloche, have shown a really interesting population of salmonids, with catches of almost 3 kilograms. The existing varieties are Fontinali, Brown and above all, Rainbow trouts.
The lake has two entry points:
1) Villa los Cohiues: You turn right and, after approximately one kilometer you arrive at an open camping ground. Among the areas suitable to fish, the most recommendable ones are the area around the mouth of Pescadero stream and all the shore area, where the park ranger's house is located (always outside the summer season). From this spot you can get to the mouth of Van Tritter stream by boat.
2) The other access is along National Route Nº 258 to El Bolsón. This takes us, some 21 kilometers ahead, to the southeast extreme where Torrontegui stream empties into the lake. As well as being really well protected from the predominant winds, this easily transited shore is the most productive one on this lake. The best moment to come is at the beginning of the season, when the water level of the stream is higher and there are still some Rainbow trouts in the area hungrily, awaiting the spawning season.
