Water always flows down a river, so upstream is the opposite direction from the direction in which the water flows.
Welll lol
The answer is... A river only flows down hill
there are rapids not very far upstream
Downstream. The source of a river is always upstream.
it slows down because first it rushes down from mountain and then slows down right at the end when it goes into the sea/ocean/lake.
a lock is a system that allows ships to travel upstream and down stream
No, a river only flows one way, they either flow upstream or downstream not both.
In a canoe Im from the wanganui river. they travel in a canoe :)
The upstream of a river is its mouth, AKA, the opening to the ocean, and everything in between. Downstream is the source, AKA the "beginning", such as a lake, and everything in between.To put it simply:A RIVER:(Mouth)=--------------------------------------------------------------------------------0 (Lake) Downstream
