Morrow repeated his concerns on another media outlet.
''I suspect we may find people have been deceased.'' he said.
Friday 6.45am: THE levee broke and the streets of Lismore quickly became rivers of water very early this morning.
Northern Star reporter Hamish Broome said wherever you looked water from the river was gushing down.
"It's ankle deep and rising," he said.
"Water is coming down between the cinema and Mary Gilhooleys then turning right towards the roundabout at Woodlark and Keen Street, then turning left and heading down towards Dawson Street."
Hamish described the multiple streams of water in the CBD as river rapids with eddies and flows.
"It's like a thunder river rapid," he said.
"Businesses will be inundated quite soon in Keen Street.
"It's risen 5cm since we have been down here.

Thursday 6.02pm: WITH the evacuation alert given to businesses in the Lismore CBD people are starting to move their stock.

"We have little time to pack after the water goes across the levee."
In the 10 years Ms Ahern has been running their business in the Lismore CBD water she has never seen water over the levee.
"We've had tips from other people about it being muddy and smelly," she said.
"We have a lot of stock to move and we have a lot of people to thank who have helped us move.
