A reservoir on the San Juan River, a few kilometers from the provincial capital, with waters that shift from green to turquoise and pejerrey (silverside) and carp. A scenic lake at the foot of the pre-cordillera, closely tied to the city of San Juan.
The pejerrey is fished from a boat and from shore, best in the cooler months; the carp gives bottom fishing. Ullum has yacht clubs, ramps and beach spots, and combines fishing with water sports and San Juan mountain tourism.

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.
Bottom fishing with boilies, corn or dough and a hair rig. Medium gear with rod pods and a bite alarm; it withstands long fights.
