A fascinating documentary that shines a light on global scientific and environmental issues.For almost 60 years, Lake Ontario has been under lockdown - surrounded, controlled and managed more than any other large lake in human history. It is the most human controlled lake on the planet. Its water levels have been managed to the exact inch to provide for stable water lanes for shipping and for hydro power. Its shore lines have been changed and its natural marshes and beaches altered. But what happens when the ebb and flow of such a vast aquatic ecosystem is replaced and turned into the equivalent of a bath tub with its water stabilized year after year? Will the lake be allowed to be returned to its natural and fluctuating water levels? Or will Lake Ontario continue to be a Lake under lockdown?
