El río Barrancas marca el límite sur de Mendoza con Neuquén y baja de la zona de las lagunas de altura como Carilauquen, en el sistema de Llancanelo, hasta juntarse con el río Grande para dar nacimiento al Colorado. Es agua fría y clara de montaña, correntosa, donde se afirman la trucha arcoiris y la trucha marrón.
Se pesca con mosca y con spinning: ninfas y streamers a la deriva en las tablas y las pozas, cucharitas y señuelos chicos junto a las barrancas y los veriles. Por lo común, la temporada rinde mejor cuando el caudal de deshielo afloja y el agua se aclara, del otoño al arranque de la primavera. Pesca de confín, entre bardas áridas, viento sostenido y la sensación de estar en el borde mismo de dos provincias.
captura y devolución obligatoria del 1 may al 28 jun 2026 (cuenca Barrancas).

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.
