Yelcho Lake is a large fjord-shaped lake located in Chilean Patagonia, in southern Palena province of Los Lagos Region, Chile. The lake receives the waters of the Futaleufu River at its southern tip, near the tiny settlement of Puerto Ramirez. The river then flows northward through mountainous and glaciated terrain, until it outflows via the Yelcho River north-west and empties into Gulf of Corcovado, near Chaitén. The lake is a used for fly fishing, and several lodges and hotels operate on its shores.
