I have a tiny feeder brook that goes through my property. There's no trout in it for most of the year, but in the fall breeding brookies will move up from the main stem to build their redds
This can also be the season with the lowest water.
I afraid that I don't get around to it every year, but I try to wade the length and clear out the dead falls that cause the silting that blocks the flow.
It's pretty swampy back there and the water needs a channel or it finds other ways
Just my own personal improvement to solve a specific problem
I do love it when we have a good recruiting class.
