The Courier understands a woman in her 30s landed in the lake and was found unconscious.

A woman was airlifted to a Melbourne hospital following an incident at Lake Calembeen yesterday afternoon.

Paramedics attended at 4.45pm and she was flown to a Melbourne hospital in a critical condition with multiple injuries.

Discussions on whether the jumping towers at the lake should be removed have been ongoing for more than a decade, with Hepburn Shire Council raising safety concerns in the past.

There has long been staunch community support for the towers, with residents opposing the removal of the top 10 metre platform on the tower before work was ultimately carried out in 2010.

A seven-metre and five-metre platform remains. The diving tower is on the Victorian Heritage list.

Calembeen Park is Crown land that is managed by Hepburn Shire Council.

A council spokesperson said on Thursday council was aware of the incident at the Calembeen Park Dive Tower.

"Our thoughts are with the person involved and their family and friends," the spokesperson said.

"We are currently gathering information regarding the incident and are unable to make any further comment."

The last council management plan for Calembeen Park dates back to 2009.

Community members have in the past called for council to repair the dive tower rather than taking it down.

The three-part water body was created by dredging and gold mining in the early 1900s.
