Brown Trout in some rivers will migrate up and down the river depending on water temps. If the temps in your area stay cool those fish will likely stay there all summer and if the temps in the lower end of your river get to warm you may find more trout start moving up into your area.
I would also suggest trying Fluorocarbon line in a higher strength which will give you more chance of keeping bigger fish out of the wood but still having the low visability in the line.
They also feed daily on insects so try small cadis larva, mayfly and stonefly nymphs.
