El arroyo Yaucha es un curso precordillerano chico del Valle de Uco, por la zona de San Carlos y Pareditas, que baja del faldeo andino con agua fría, clara y de poco cauce. En sus pozas y correderas menudas se esconden trucha arcoiris y trucha marrón, atentas y esquivas como corresponde a un arroyo de aguas transparentes.
Es pesca fina y de acecho: mosca con secas y ninfas livianas presentadas con cuidado, y spinning con señuelos chicos donde el cauce lo permite, cuidando la aproximación para no espantar el pique. Como regla general, conviene el otoño y el arranque de la primavera, cuando el deshielo afloja y el arroyo corre bajo y cristalino. Pesca íntima, de caminar la orilla agachado entre arbustos, con la precordillera árida cerrando el paisaje.
captura y devolución obligatoria del 10 jun al 30 oct 2026.

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.
