Heard barbel are coming from the Calder in some of the faster flowing stretches, it too has chub.
The Dane is in reasoable traveling distance for a few hours barbel/chub fishing summer time, probably a bit iffy going over the tops winter though.
A couple of friends from thar area used to chub fish the Aire on a reglar basis. One tells me he is catching some good carp locally, but he wont say from where.
