In the autumn I read news that predicted "the hardest winter in 100 years" or so. Seems like you guys got that "the winter of all winters" but at least my country got almost no winter at all.
There was 3 week period with black frost and no snow. That's all. Ice managed to get approx. 40 cm thick only because of lack of snow but it has gone now. The first real snow appeared about 2 weeks ago and almost everything melted.
I'd predict that only some unlucky people will have fish kills this year. No serious winter fishing too.

Yeah, but I live quite far from you...
