Am I right in thinking that, in summer, the fish will mainly be out in the middle where there's maximum flow? I fish the Thames which I'd describe as a medium flow river.
I realise there are exceptions. Like I think they will still hide under boats, even in summer. Do you agree?
A related issue is where they will be vis a vis depth. Am I right that roach will tend to be up in the water, and will certainly like a dropping bait? That's a nuisance for me, as currently I can't see a float much further than under the rod tip, but that may hopefully change after a cataract op.
And perch, now that's another question. Half of me thinks they'll be close in cos they don't like much flow. But on the Thames they can be very active chasing the bleak out in the middle, you see the bleak jumping out of the water.
So am I right that ledgering has it's problems for both roach and perch in mid summer?
What's your experience of summer fishing?
