Lake Musters and Lake Colhue Huapi - Outflow

Outflow

Both lakes suffer naturally of a severe evaporation process in the dry patagonian environment by means of strong winds action and solar radiation. In shallow Colhué Huapi evaporation is much increased. In past decades, when excessive inflows did take place, water discharged to the birth branches of Chico river and eventually reached Chubut river. This occasional process last happened in 1939, since then Chico river is mostly a dry one.
