Freshwater
Wight coastal village
Freshwater is water with low salt content, as opposed to seawater or brackish water—the water of rivers, lakes, and most groundwater.
As an adjective, it describes organisms or environments associated with such water: freshwater fish, freshwater ecosystems.
Figuratively, freshwater can mean inexperienced or provincial, though this use is dated.
