Question About Bugs and Stocking After Dam Work

[Laxref29]

Hi all,
I'm trying to plan ahead for a trip back to the Little Mo once stocking resumes. With the recent water issues and dam repairs, I'm wondering about the insect base. If the river has been essentially "reset," are there still reliable midge, caddis, or mayfly populations to support the trout right after an October stocking?

Or should I expect the fish to be more tuned in to eggs, worms, buggers, and other attractors until the bug life rebuilds?

Would really appreciate any insight from folks who have been on the water or know how quickly the insect populations bounce back here.

Thanks in advance.
