River is a natural watercourse flowing toward an ocean, a lake, a sea, or another river. A river is part of the hydrological cycle. Water within a river is generally collected from precipitation through surface runoff, groundwater recharge, springs, and the release of stored water in natural ice and snowpack
Streams are a body of water with a current confined within a bed and stream banks. A stream can be referred to as a branch, brook, or a rivulet. A stream has a watercourse less than 60 feet wide.
