what's the difference between a swamp and a lake
a swamp is a body of water that has some vegetation and a lake is just a body of water surrounded by land. A reservoir is a man made lake whereas a lake is a result of glaciation that has changed over time and formed a U-shaped valley and the lake will be present in the v â¦ alley.     A lake is an inland body of freshwater & a reservoir is a man made (artificial) version of the same thing.
