Invasive Eurasian Water Milfoil levels in Taunton Lake in Newtown are down significantly.  The Newtown Bee reports that an August 23 survey of the lake’s shallow-water perimeter is down by 75 to 80 percent.  Sterile grass carp were added to the lake in recent years to feed on the invasive weeds.  Newtown Planning Director George Benson oversees a milfoil control project at Ball Pond in New Fairfield, where grass carp are also stocked.  Milfoil, which can pose a danger to swimmers and boaters by getting tangled on limbs, propellors and fishing tackle, was first found in Taunton Lake in 2007. Taunton Lake has only limited public access.
