BOLLARDS which have been put up along the eastern road at Lake Ainsworth at Lennox Head will help protect the lake into the future, according to the Ballina Environment Society.
But while president Lyn Walker says it is "a good start", she still wants the road to be closed permanently.
"It's good news that the bollards have been installed and we are pleased that it has happened," she said.
"However it's not enough.
"That road needs to be completely blocked off.
"Whenever we get heavy rain, as we did several times last year, the road acts a conduit for the water and washes all kinds of chemicals and toxins into the lake.
"We also get erosion on a huge scale.
"At the moment the bollards are stopping cars from parking on that side of the road, so that's a really good thing.
"But it's a band-aid solution to the problem."
Dr Walker said she was unsure what would happen to the eastern road in the longer term, with some reports indicating that the road would not be closed until the western road was sealed.
President of the Lennox Head Residents' Association, Fred Goodman, said his group believed there were several issues that needed to be resolved before the eastern road could be permanently closed.
The Lake Ainsworth eastern road had to be closed on several occasions last year after rain caused the lake to flood over the road.
