We began implementing our 2018 Comprehensive Variable Milfoil Management Program for Lake Winnisquam in June. This lake-wide program included the removal of variable milfoil from a number of locations along the lakeshore (including new locations identified by our new Weed Watcher Program) by diver-assisted harvesting by Gilford-based Aqualogic Inc. Throughout the summer a total of 843 gallons were removed. This was followed in September by a controlled herbicide application by SOLitude Lake Management in 19.5 acres where the milfoil growth was the densest. We were not able to treat the milfoil in Jay’s marina this year due to the recent reactivation of a public water supply well in close proximity to the treatment area there. We’re looking to treat this area next spring with an alternative herbicide that has recently become available and does not have the same use restrictions.
Our milfoil management program was funded through a grant from the New Hampshire Department of Environmental Services (NHDES), local matches from the towns of Meredith, Belmont, Tilton and Sanbornton and the City of Laconia, and contributions from several neighborhood associations, as well as our members. We extend our deep appreciation to all. This is the first time that management of variable milfoil has been undertaken on a comprehensive, lake-wide basis on Winnisquam, and it’s our intent to continue this collaborative effort for as long as is necessary to control the growth of the milfoil and prevent further spread. We’re currently working with the NHDES to finalize next year’s comprehensive milfoil management plan and have begun soliciting bids for the work.
