Its late and I've had a long day at the BW AGM (well worth the effort) but I think you need to remember that the other way around. The flow runs across the canal below Alrewas lock so when you pass the weir in that direction you have the (flow) diagonally with you. I have to get Quidditch out of Wychnor in the next couple of days and I need to take into account that I have to go against the flow and risk being pushed diagonally towards the weir. Seems to me that if your proposition is correct, the board at Wychnor should reflect higher than at Alrewas lock (having said that, I suspect that both are 'accurate' but as the level at that lock is close a mill stream as well as the Trent crossing, there is actually more water there than their is at Wychnor lock which is around half a mile from the weir. Cheers Will I hope to do that tomorrow (inshallah). Cheers Will
