State agencies are investigating whether a pesticide sprayed for mosquito control caused a fish kill in an Addison County lake earlier this month.
The fish die-off was seen in Fern Lake a few days after trucks applied a chemical in the area to kill adult mosquitoes.
Leicester resident Zachary Saxe has lived near Fern Lake for a decade. He often fishes and swims there, and the first weekend in June his swim was interrupted by the sight and smell of dozens of dead fish. Saxe, who once worked as a wildlife technician, went out to collect samples in plastic bags.
