brackish water

Partly salty liquid

Brackish water is water that falls between fresh and salt water in salinity—typically found in estuaries, coastal lagoons, and river mouths where freshwater meets the sea.

The term distinguishes this intermediate state from both drinkable freshwater and full-strength ocean water: The marsh was fed by brackish water from the tidal creek.
