I've always thought that the boards - particularly the one at Bagnall Lock, as you enter Alrewas, was to provide advance warning so you could wind below the lock otherwise you would have to back half a mile when you saw the fast flow and gauge at Alrewas lock . I think the position of the one below Wychnor lock is again just before the winding hole. So I have not thought they added any value apart from giving advance interpretation of the gauges. Richard
