Caleufu River

When the Meliquina and Filo Hua Hum rivers merge they create the Caleufu River which flows for 40 miles before draining on the Collon Cura River (now Alicura Reservoir).
It is floatable from opening day until early January depending on snowmelt and rains. 
It is an excellent river for streamers (early season) to dry flies and nymphs. 
Ask your guide when the "minnow hatch" occurs for some epic fishing in the lower reaches.
