Freedom — September 16, 2009 – More milfoil has found its way into Ossipee Lake. Late Tuesday, state officials confirmed that samples taken from Pickerel Cove on Broad Bay are invasive variable milfoil.
Lake property owner Jim Fitzpatrick reported the weed to Ossipee Lake Alliance, and a volunteer collected a sample for processing by DES.
After viewing the area, which is east of Cassie Cove, Alliance co-director Susan Marks said the infestation is in deep water and is extensive but appears to be relatively young. She said the Alliance will work with state and local officials to develop options for treating it, which could include mechanical harvesting, hand-pulling or an application of chemicals.
Milfoil is spread from lake to lake by boats, making inspections of boats and trailers an important preventative weapon. There are yearly Lake Host inspection programs at the Pequawket Trail and Pine River public ramps, but all other ramps rely on boaters to inspect their boats and trailers voluntarily before launch.
Once established, milfoil is spread within a lake system by currents as it is chopped up by boat props, with even the smallest fragment capable of establishing a new infestation. At present, there is no method of permanent eradication.
Other infested locations in the lake system are upper and lower Danforth Pond, Danforth Brook (Ossipee Lake Marina vicinity), Phillips Brook and an adjacent portion of Leavitt Bay, and the Ossipee River.
