still learning---how does a trout find it"s spot beside the streamside log
after it has been chased out to midstream?
eye ? nose ? [seems current would deny this }? brain memory ?

nothing else to think about when you wake up at 4am and paper does not
arrive till 6

Hmm, I doubt if anyone actually knows, and the trout ain't telling.

But I suspect that it is by nose/lateral line. Even though the moving
water washes away scents, I suspect that the substrate continually
recharges the water with things that can be sensed by the fish.

I once lived downwind from a pulp and paper plant. Even though the
wind continually moved the odor away, it was always being recharged,
and was always there. I think the 'scents' in the water might be the
same.

They probably don't worry about the current conditions on ROFF, so
there's lots of excess brainpower...

Seriously, I'd offer it is probably using some of the same "clues"
salmon use to find their way back to "their" river tributaries area:
clues that the "traveler" probably isn't even aware of - sight, chemical
triggers, smell, "memory," even magnetic field clues in long-distance
travels, etc. AFAIK, it isn't known absolutely how fish "know" where to
go, but there are theories on what's likely.

Hey, humans generally find their way back home after a trip to the
grocery...or even the neighborhood bar...so how hard could it be...?

Interesting question. Not being a fish scientist, I can only guess;
but I'd say that they don't find their way *back* to that spot, they
simply find the same spot again, the same way they found it in the
first place, current, cover, food supply. If it's the best available
spot in the pool, it makes sense the fish would eventually find it
regardless of whether they'd been there before or not.
