Yes, your right, I should have read more carefully, and got the boards the wrong way around! As you say, the board at Wychnor maybe should be lower, and with the main flow going down the river the levels are probably higher at Alrewas in times of flood - which means I have a better chance of saying to BW if stuck again at Alrewas - well it might be red here, but its yellow at the other end, so it must be OK to let us through! :-) I wouldn't mind, but the flow there even in high flood (maybe not summer 2007) is still no worse than the tidal bit of the Trent. Good luck for today. Mike -- Michael Askin http://shoestring_DOT_zapto_DOT_org/
