Inflatable adventure park planned for Lake Burley Griffin this summer

Canberrans would be able to bounce around Lake Burley Griffin on a new attraction planned for the waterbody this summer.

The National Capital Authority is seeking the public's feedback on plans for an aquatic adventure park at Tarcoola Reach swimming area, off the banks of Black Mountain peninsula.

The inflatable obstacle course would include tunnels, bridges, slides and swings.

The proposed attraction would be open from November 2019 to April 2020.

The idea was first pitched last year to the authority and ACT government by a small group of friends, who have formed a company called Canberra Aqua Park.

The company's director, William Yeap, told The Canberra Times that the group came up with the idea while fishing in Lake Burley Griffin.

"We thought that Lake Burley Griffin was a really nice spot to do this type of thing. We've seen other parks like this in places like Melbourne and I think it's a great way to promote a healthy lifestyle," he said.

Mr Yeap said the group would spend about $250,000 to set up and operate the park. The ACT government and National Capital have not provided any money towards the venture, but will be required to approve various licences to allow it to go ahead.

Application documents presented to the authority noted that park users would regularly submerge in the water as they jumped and climbed across the course, meaning the lake's water quality was "critical" to the operation.

High levels of blue-green algae typically force the closure of Lake Burley Griffin to swimmers for periods in late summer and early autumn.

Mr Yeap's company investigated the option of locating the obstacle course off Weston Park, but eventually settled on the Black Mountain peninsula site because of its "superior water quality".

Water monitoring data showed the Black Mountain section had been closed on average two weeks a year since 2011-12, compared to about seven weeks a year at Weston Park.

National Capital Authority chief executive Sally Barnes said the operator's licence would specify that the aqua park would have to close if there were high levels of blue-green algae or bacteria detected in that section of the lake.

"Everyone is going into this with their eyes wide open knowing the risks, but luckily this is one of the cleanest areas of the lake," Ms Barnes said.

Ms Barnes hinted that the aqua park could be the first in a wave of new attractions at Lake Burley Griffin, saying the authority was "keen to explore ways to responsibly provide access to, and activate, the lake".

When pressed by The Canberra Times on what activities or attractions were under consideration, she said: "Watch this space ".
