En el sur mendocino, el río Atuel nace del deshielo cordillerano y baja correntoso entre montañas áridas, por la zona de El Sosneado camino a San Rafael. Es agua fría y transparente cuando el caudal afloja, con trucha arcoiris y trucha marrón que se hacen fuertes en esa corriente de los Andes.
Se pesca con mosca y con spinning liviano donde está permitido: secas y ninfas en las correderas, streamers en los pozones y las juntas más profundas. El truco es salir cuando el río baja y aclara, que es cuando mejor rinde. En términos generales, la temporada estival, de la primavera al otoño, es la ventana buena. En los tramos con captura y devolución cuidá cada pieza: es un río de montaña que se disfruta con pesca prolija y respeto por el recurso.
captura y devolución obligatoria del 1 may al 28 jun 2026; veda en tributarios sensibles.

In October the species of Río Atuel are past their best moment. Off season does not mean there is a closed season.
In Río Atuel it is worth going when its main species bite: Brown trout (NOV–APR); Rainbow trout (NOV–APR).
Río Atuel is in the province of Mendoza.
Spinning (general use, trout of 1 to 3 kg):
Fly:
For trophy specimens (5-10+ kg at the Strobel): step up the power—medium/medium-heavy spinning with 15-20 lb braid and a robust fluoro leader, or a 7/8 fly outfit—because these are fish with strength and runs far superior to the average trout.
In every case: a well-adjusted drag, sharp hooks (barbless if you are going to release), and a rubber net to handle the fish with the least possible harm.
