People strolling by Lake Victoria in Stratford may notice something unusual. On Monday, two small yellow buoys will be put into the water to test a new device meant to improve the lake’s water quality. Stratford’s community services department will put one buoy just east of Tom Patterson Island, while the other device will be just west of the Waterloo Street bridge. “These buoys (known as Equilibrium Modulating Fluids Devices), are designed to help improve water quality by enhancing the natural exchange of gases between the water and the atmosphere,” the City of Stratford said in a social media post. “This helps support healthier oxygen conditions in the water and creates an environment that can help reduce issues such as odour and the buildup of organic material.” The buoys are solar-powered and do not add chemicals to the water. The plan is to keep them in the water until the end of October.
