Colorado, river, Argentina
(klrä´th) (KEY) , river, c.550 mi (885 km) long, rising from tributaries in the Andes and flowing SE across S central Argentina to the Atlantic Ocean. It marks the northern limit of Patagonia. It is also a rough boundary between the commercial agriculture to the north and ranching to the south. The Colorado’s lower course splits into two branches that flow into the Atlantic Ocean; the river often overflows its banks in spring.
