Lake Rivadavia

Lake Rivadavia sits in a fjord-like trench at an elevation of 527 metres (1,729 ft) between glaciated mountains rising to Sierra Rivadavia, 1,924 metres (6,312 ft) on the east and Cerro Coronado, 2,097 metres (6,880 ft) on the west.[2] Glaciers descend the mountain slopes to an elevation of about 1,500 metres (4,900 ft). The Jara River joins the Lake Rivadavia on the west side near its southern end.[3] The outflow from the lake is the Rivadavia River, which flows 6.7 kilometres (4.2 mi) to Green Lake (Lago Verde), 151 hectares (370 acres) in size, a much smaller lake than Rivadavia. The Rivadavia River and Lago Verde are famous for trout fishing with "turquoise water, Jurassic Park like jungle, and snow-capped peaks." Rainbow, brown, and brook trout and landlocked Atlantic Salmon are found in the lake and river, all of them introduced rather than native.[4]

The outlet from Green Lake is called the Arrayanes River. A pedestrian bridge crosses the river near the outlet. The Arrayanes is joined by the outlet from Lake Menéndez, and flows about 5 kilometres (3.1 mi) to Futalaufquen Lake. Argentina Provincial Highway 71 follows the shoreline of Green Lake and the Arrayanes River to Futalaufquen Lake. Campgrounds and lodges accommodate visitors.[5]
