On Saturday, May 14, seven volunteers from Three Mile Lake Association attended Water Testing Training at Rosseau Lake College. The training was put on by the Muskoka Lakes Association as part of their Water Quality Initiative. These volunteers will be collecting samples at four locations on and around the lake over the long weekends from May until the end of August. The samples will be sent to Dorset Environmental Science Centre for analysis and then included in a report which will be published in late fall.
