Toyama fishing rivers

What are the best rivers to fish in Toyama?
I recently went to the river that leads to Banbajima/馬場島荘.
There were many others fishing there, but no one had any luck.
Does anyone have any other recommendations?
Would prefer somewhere in the mountains that's not touristy.

That lodge around rivers placed small check-dam(砂防ダム/sabou-dam)/weir(堰/seki) a lot.

Unfortunately in upper area using fish passage/ladder(魚道/gyodou)-less type usual no good
as habitat very risky found easier by fish eaters(wild animals birds and more).

Also higher ground still water cold by melting snow and not enough bugs for feeding.
So mountain stream fishing(渓流釣り/keiryuu-zuri) needs "map reading skills" before going.

Mountain stream fishes are smart with very high wariness agaist all enemies(fish eaters include fisherman).

BTW,
NO asking at local fishing tackle stores(釣具店/turigu-ten 釣具屋/turigu-ya)
also local fishermans or lodge staff before/after fishing?
(bought "river fishing license ticket/遊魚券 yuugyo-ken" and fishing rules?)

What time been there?
How about river conditions? (water color/temp/water amout)
What way of fishing did? (by lure? fly? live bait?)
Not matched tackles? (line,hook size and more as undrerstanding target fish name and their life?)
Seen a lot of fish rise?

How about wild baits/bugs condions river around and into water?
Used polarization sunglass(偏光グラス/henkou-glass)?
Attacked down-stream to up-steream?

Anyway,this is most important Q :)
No bite(アタリ/atari) also No following/attacking?
