BELGRADE, Maine — Three years after the state began a controversial plan to use an herbicide to rid a Belgrade lake of an invasive plant, the plant hasn’t reappeared.
John McPhedran of the state Department of Environmental Protection told the Waterville Morning Sentinel that there’s no evidence of Eurasian water milfoil in Salmon Lake. He said the lake could be removed from the list of infested waters if it remains clear this year.
The milfoil can form dense mats and congest waterways. It was first discovered in the lake in August 2008.
In 2009, the state announced plans to control the milfoil with an herbicide. But residents expressed concerns the chemical would harm other wildlife.
McPhedran said there’s no sign the chemical has damaged the cove where it was applied in the highest concentration.
