Both Ends (9) : Cromford Canal

One end of the Cromford Canal, at Cromford Wharf in Cromford is not in doubt. But with the canal only navigable for a short distance and for much of its route barely surviving at all where is the other end of the Cromford Canal these days?

Is it at the end of the Wigwell Aqueduct where the current limit of navigability is? Or where the canal meets the Erewash Canal? However there is a big stretch before that without any water. I've chosen Ambergate where the waters peter out into a bit of a dribble. This is the end of the continuous water from Cromford Wharf.
