Lake Bonney open for business after 30 years THIRTY years after it was closed, Lake Bonney, in SA's South East, has been reopened for use by kayaks and canoes. The State Government has announced the opening following public consultation with the South East community. Lake Bonney was closed after the 1983 Ash Wednesday bushfires when logs were stored in the lake for future recovery and milling. Now State Government inspections of the lake have deemed the waters to be safe enough for use by human-powered vessels. Transport Minister Tom Koutsantonis said the Department of Planning, Transport and Infrastructure would continue to monitor the lake and remove any potential hazards. He said he hoped powered vessels, such as speedboats and jet-skis, would eventually be reintroduced.
