No you certainly get lot less on the northern broads and rivers, but you still get a little, my feelings with the Wensum and the Yare are that Norwich is primarily the beginning of the problem as you obviously get people throwing rubbish in, but you also have at least two storm drains, that when we have any amount of rain just pump raw sewerage straight into the river. Yes it's just shocking as only a few miles down river kids are paddling and sometimes swimming or at least splashing about a bit during the summertime, yes it doesn't bear thinking about, does it?
