Lake Lagunillas

Lake Lagunillas is a lake in the Andes of far southeastern Peru. Lagunillas is at an altitude of about 4250 m and it is located just northwest of Lake Saracocha. These two lakes are part of the system drained by the Coata River, which flows in a generally easterly direction until entering westernmost Lake Titicaca, about 50 km from Lake Lagunillas as the crow flies.

In 2014, the pupfish Orestias luteus made up slightly more than 70% of catches in fisheries, with the remaining being the introduced rainbow trout, a species also farmed in the lake. Lake Lagunillas is home to the unusual and relatively large "escomeli" form of the Titicaca water frog.
