Yes, but it does not necessarily have those two connotations in other languages (which is the issue here). In Portuguese, if you want to say "fresh water" (as in, "low-salinity water"), you use the term "sweet water", rather than "fresh water" ("fresh water" can only be interpreted either as "cold water" or "non-stale water", but never as "low-salinity water").
