Lake Marcapomacocha[1] [2] [3] (possibly from Quechua marka village, puma cougar, puma, qucha lake)[4] is a lake in Peru. It is located in the Junín Region, Yauli Province, Marcapomacocha District. Lake Marcapomacocha lies south of Lake Marcacocha and east of Lake Antacota. It is situated at a height of about 4400m (14,400feet), about 3.67 km long and 1.95 km at its widest point. It has a catchment area of 141km2.
The area where Lake Marcapomacocha is located is important for the breeding of the andean goose, the crested duck and the giant coot.[5] Bogs in the area are home to the rare diademed sandpiper-plover. The rainbow trout has become a naturalized species in the lake.[6]
The most important threats to the lake are the excessive hunting and the manipulation of water levels.
