Lake fish-kill concern

By HUGH KEARNEY

HUNDREDS of fish have died in a man-made lake on the Vintage Lakes estate at South Tweed Heads.

A resident of Port Drive whose home backs onto the lake said he didn't know the cause of the fish kill, but thought it could be due to a heavy infestation of weed depleting the waterway of oxygen and killing the fish.

George Woolley said he first noticed the dead fish, mostly mullet, on Thursday.

"There were about 20 or 30 dead fish on Thursday, but today (Friday) there were hundreds and hundreds," Mr Woolley said.

"They are dotted all over the lake, you couldn't count them."

"It's a bloody mess and a real shame because the area is so well maintained."

Mr Woolley said 90 per cent of the lake was covered by a brown weed, similar to chickweed, which seemed to double its volume everyday.

He said the weed appeared different to the red azola weed which had caused a major headache for residents and council two years earlier.

"That was pretty bad until they brought in a weevil to control it, which worked really well," he said.[EP]

"What the cause or the answer is this time, I don't know."

Mr Woolley said the dead mullet measured up to 60cm in length and appeared to be in quite good condition.

He said a Tweed council crew was cleaning up the fish late on Friday afternoon.
