I'm being cynical here, but up and down 2ft in a week, I should be so lucky. My local river, the Wear, can come up 10ft overnight and be down again in 48 hours, as I'm sure many other spate rivers do. I do appreciate your problems though, its now months since my river was anything like stable. When it is at normal winter level it usually coincides with very heavy overnight frosts. Roll on the 15th March then I will have a legitimate reason for not fishing. The springtime, a time of rejuvenation - including me, I hope!
How is the Cherwell fishing these days? I have not visited the river for some years now. Out of all the southern rivers I have fished, I much prefer the Cherwell. Although the upper Gt Ouse has bigger fish it doesn't have the same appeal as the Cherwell for me. Probably because it was the first southern river I ever fished.
