Give one of the Bailiffs a ring mate, Mike Grief is normally a good bet, you'll get a number for him on the internet if you search for the KLAA angling club. Ask where the match fish are coming out and head there. Failing that, head for an area away from immediate access points and fish to any features you can find.
Otherwise, it may pay to ask Mark Barrett if he'll help you out, he has a lot of current knowledge on the water or visit
www.averagezedheaven.com you will find a little more info, although a little dated now, on the drain.
Kind regards,
Dave
Good luck mate!!!
