freshwater
Rivers and lakes
Freshwater is water that isn't salty—rivers, lakes, ponds, and streams as opposed to oceans and seas.
As an adjective, it describes organisms or environments associated with such water: freshwater fish, freshwater ecosystems.
Figuratively, freshwater can suggest inexperience or provincialism, as someone from inland waters rather than the open sea.
