El río Mendoza baja bravo desde la alta cordillera, cruza Uspallata y se descuelga por Cacheuta rumbo al Gran Mendoza: agua de deshielo, fría y correntosa, encajonada entre cerros áridos. En sus tramos serranos guarda trucha arcoiris y trucha marrón, que aguantan la corriente al reparo de las piedras y los pozones.
Se pesca con mosca y con spinning: ninfas pesadas y streamers a la deriva en las tablas y los remansos, cucharitas y minnows buscando los veriles junto a la roca. Por lo general, conviene esperar a que el caudal de deshielo afloje y el agua aclare, del otoño al arranque de la primavera, cuando el río se vuelve legible. Pesca de sol de montaña, viento seco y andar entre pedreros, con el bramido del agua de fondo.

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.
