There has been no sighting of a 76-year-old Nimbin fisherman, who regularly fished at Clarrie Hall Dam in his kayak, despite a major search.
The man left home on the fishing expedition on Thursday and family reported him missing on Friday.
A Westpac Helicopter search on Saturday, a police and SES hunt over the weekend and the police divers searching the dam yesterday failed to find any trace of the man.
His kayak and other belongings were found near netting that filters weed from the water supply and that is where police divers will focus their search today.
