before you go check bylaws
i know if a river has trout
in it you cant use a suspended bait ie float fishing,
and it will be worm or fly only in the close season
if you did not know you cant fish for barbel till
the 16th june i would check before you go
because the EA will be out in force over the bank hols
If it is the day ticket stretch at Tadcaster you will find that it is out of bounds for all fishing until the 16th. I'm not too sure about the Leeds ASA stretch though and stretch above the bridge belongs to Tadcaster AC. You have to be a member to fish there.
Try the Leeds stretch at Pool in Wharfedale as you can fish for trout there and it is day ticket.
