You reach the stream/ river and there's no hatches nor signs of fish feeding. Nice pool, riffles, pocket-waters.
Trout river: browns, rainbows, brookies, cutts.
How do you start?... Streamer? Dry? Nymph? Dropper? Wet? Soft?...etc.
In my case, the first choice is a dry (caddis or foam terrestrial)...second choice a soft-hackle, third choice a nymph.

Good luck
