There's a little river near me in Manchester,It fishes like your brook,had some nice Trout out of it,and some huge Chub,and plenty of minnows.
I fish with a 16's hook with a maggot on it,that's tied to a number 8 hook(in the bend.)
I catch a minnow on the maggot,and then transfer it live onto the bigger hook.
I use a bucket with an aerator in it(battery)and keep live minnows in it.
Those big Chub and Trout love live bait.
I trot it with a bubble float,with the minnow just off the bottom so it can't hide on the bottom.
The Chub are easily spooked,so I stay off the skyline and move around nice and quiet.
When you think you are going to Blank,a minnow never fails.
I've noticed that little rivers with minnows in them produce bigger trout and Chub,and came to the conclusion that they grow bigger if they have a live diet.
