WHAT IS A STREAM?

A stream is a body of water[1] with a current,

confined within a bed and stream banks. Depending on its location or certain characteristics, a stream may be referred to as a branch, brook, beck, burn, creek, crick, gill (occasionally ghyll), kill, lick, mill race, rill, river, syke, bayou, rivulet, streamage, wash, run, or runnel.
