Really?

I wonder who can know this maze of channels in such degree (s)he could improve significantly a long-term work of professionals from OS. A fisherman? Is there any fisherman? Or perhaps a maniac angler or a maniac canoeist. The same with drainage ditches with missing culverts. Maybe a farmer on own farm. And missing culverts can be easily spotted on the Bing without any local knowledge.
Although such import is far from being perfect it is much better than leaving a map as a terra incognita what is a big part of rural Britain on OSM.
