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.
