I have fished this stretch many times and the advice given is spot on. Really important to check the Kielder releases as this is a critical factor. We have had a good deal of water into the North Tyne and there should be a decent head of fish in the beats by now.
I have found yellow flies work really well in the peaty water you are likely to encounter.
This beat is not the worst North Tyne stretch for wading but I would strongly recommend a wading stick.
I agree with Mattytree and lax0341, this is a cracking bit.
Tight lines,
