EVANDALE Lake will be drained to flush out the elusive stonefish that closed the popular swimming hole for almost a month.

The Gold Coast City Council decided, after two failed rounds of Operation Stonefish, drastic action was needed.

Draining will start on August 21.

The pumping of the water could solve a few of the mysteries like what happened to the Loch Ness monster, where is Aquaman’s lair and what happened to the Suns’ ability to win.

Hiding under the water the council may even find the three-eyed fish that was nuclear-charged by Homer Simpson in Springfield in the 1990s.

It is expected to take a few days to drain the lake.

Before work can begin, the council needs to seek approval from the State Government to pump the water into the Nerang River, where the water came from.

Fishermen will net the lake to relocate marine wildlife to the river before the draining begins.

The pumping cannot start until marine experts confirm no dangerous marine organisms are in the water.

A council spokesman said while the lake was empty, about $120,000 in repairs would be undertaken.

“The lake was last drained and refurbished around 20 years ago so we are simply taking this opportunity to do those required works that will beautify the lake for the upcoming summer season and complement the cultural precinct currently under construction,” he said.

Repairs include replenishing sand in the lake, adding rock and pebble to the banks, removing debris.

“The draining and refurbishment works are being treated as a priority,” the spokesman said.

The repairs are expected to take until at least mid September.

The lake has been closed since mid-August when video was captured of a potentially deadly stonefish in the lake.

Attempts by SeaWorld divers and netting of the lake have failed to find a stonefish.

A theory has been circulating on social media the stonefish was part of a ploy to have the lake filled.

The spokesman called the theory “absurd” and said the lake was a prominent feature in the plans for the cultural precinct.
