A reservoir on the San Juan River, upstream of Ullum, with deep waters among hills and pejerrey (silverside) and rainbow trout. A scenic lake of the San Juan pre-cordillera.
The pejerrey is fished from a boat and from shore, best in the cooler months; the trout appears in the colder, deeper water. It is a quiet destination, a complement to the nearby Ullum dam, with access through the western San Juan area.

The number (0 to 100) sums up how likely the species is to be active here this month: it weighs the season, recent catch reports and, where there is a river gauge, the water level.
The pejerrey is a medium-sized fish with a delicate mouth, so the tackle leans to the fine and sensitive side. A recommended setup:
The philosophy of the tackle is simple: the finer and more sensitive it is, the more bites you will detect and the more you will enjoy the fight of this silver fish.
The gear is matched to the setting and the size of trout you are after, but these setups cover most situations in Argentina:
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.
