-
A.
headwater stream
chosen
A headwater stream is a small, often narrow and shallow watercourse at the uppermost reaches of a watershed where surface runoff, springs, or snowmelt first converge to form the initial flow of a river system.
-
B.
headwaters section
The headwaters section is the uppermost part of a river system where small streams and springs originate, characterized by steep gradients, fast-flowing water, and relatively pristine conditions.
-
C.
river distributary
A river distributary is a branch of a river that diverges from the main channel and flows away from it, typically found in delta regions where sediment deposition causes the river to split into multiple smaller channels.
-
D.
trout stream
A trout stream is a cold, clean, well-oxygenated flowing body of water that provides suitable habitat for trout to live, feed, and reproduce.
-
E.
watershed
A watershed is a land area that channels rainfall and snowmelt into streams and rivers, ultimately draining into a common outlet such as a larger river, lake, or ocean.
- F. None of above.
