ROWERS competing in today's Australian Masters Rowing Championships on Lake Wendouree ended up in the water after their boats capsized in wild weather conditions.
Multiple boats tipped rowers into the choppy waters.
Several ambulances are on scene, where one woman aged in her 60s, is being treated by paramedics for hypothermia after falling into the lake.
All races have now been cancelled.
Organising committee chairman Peter Fraser said the weather did not look like it would improve and was settling in.
"We have a criteria that we have to adhere to so we've cancelled all events for today," Mr Fraser said.

"(Because) tomorrow the schedule's already packed, we won't be adding any more events."
Mr Fraser said boats could tip over even when the weather was fine and it was unfortunate they tipped over in conditions when the water was cold.
Rowing Victoria chief executive officer Nick Ball said all athletes were competing in an average of 4.5 events over the days, so most would be able to compete on other days.
Ballarat-Wendouree Rowing Club member Kelly Steegstra said a jet ski followed her crew back to shore after all events had been cancelled.
"It was really rough, we had waves crashing into the boat," Ms Steegstra said.
Racing is scheduled to commence at 8am tomorrow.
