FIRE that burnt away bamboo on the levee bank has revealed the extent of damage the succession of floods has done at Great Marlow.
Local farmer Greg Nicholls said without the bamboo covering it up, you could see where the floods had eaten away a large section of the bank.
He said in some places it was getting close to Great Marlow Rd, the only access road for farms in the area.
"The council told us the bamboo would hold the bank in place," Mr Nicholls said.
"But you can see the water has just cut away the soil around the bamboo plants and eaten its way toward the road."
He said during a flood the flow of the river created a swirling eddy near the bank.
"This just cuts into the bank. You can see it even better if you get out on a boat and look at it from the water," he said.
Mr Nicholls and other farmers are worried what might happen in a flood when the levee banks upstream of the second Grafton Bridge are raised as suggested in an RMS environmental impact statement.
"They're just speeding the river up with these levees," he said.
"I want to know what council plans to do about it."
A Clarence Valley Council spokesman said staff with expertise in this area were not available to comment, but would attempt to answer Mr Nicholls's questions this week.
The RMS will staff displays of its EIS at the Grafton Community Centre 4-7pm Wednesday and at the South Grafton Ex-Servicemen's Club Thursday 9am-noon.
