So how small, or big, is a small creek ??

Guess it depends on your bailiwick.

In looking at your pictures, the first one is a little larger than a small creek.
The next two I would classify as small rivers.
The third, well you stated that as it should be John.

I don't know. If you fish a variety, as to size waters, the waters fished will become apparent to you as to size.

Of course, this is from the perspective of an eastern US fisherman.

Nice pics!
