Welcome to the website of the Northwood Lake Watershed Association. Through our website, we seek to keep members, non-members and all those who care about Northwood Lake and its watershed informed and involved in maintaining and enhancing the health and beauty of this precious waterbody.
Facts You Should Know About the NLWA:
The Northwood Lake Watershed Association (NLWA) is a 501(c)(3) non-profit New Hampshire corporation. Our elected officers, directors and members come from all three towns that have a shoreline on Northwood Lake: Northwood, Deerfield, and Epsom; the NLWA has no direct affiliation with any of these towns. The purpose of The Northwood Lake Watershed Association is to preserve and protect the quality of Northwood Lake and its surroundings. Variable milfoil first appeared in Northwood Lake in 1990. In 1992, the NLWA was formed to deal with the milfoil problem. Our activities include the monitoring, treatment and control of milfoil. Our mission is entirely one of protection and conservation. We have been working closely with the Boards of Selectmen in Northwood, Deerfield and Epsom to secure much-needed, ongoing economic support... an effort that has been largely successful. For the 2016 season, we have secured funding from all three towns: Northwood ($10,000), Deerfield ($8,000) and Epsom ($3,501). Even with our DES grant (40%), a significant gap remains. That remainder will have to be made up by private and corporate donations.
NLWA’s efforts are focused on three methods of treatment and containment:
Herbicide Treatment: 2,4-D – trade names Aqua Kleen and Navigate. 2,4-D is generally applied to the aquatic environment after being mixed with clay and formulated into pellets. Once on the waterbody bottom, the herbicide is slowly released over time and is absorbed by the roots and leaves of the plants causing abnormal growth responses. This usually kills the plants within two weeks.
DASH (Diver Assisted Suction Harvesting): is a very productive and effective method of removal. When suction harvesting, a diver physically removes (hand pulls) the targeted plant, being careful to remove the entire root system and minimize fragmentation. They then place the plant into a suction hose that takes the plant to the surface. We are not dredging the lake bottom, but simply hand pulling the target plants and using suction to get them to the surface.
Northwood Lake Shoreline: 42,651 ft.
Northwood: 27,232 ft. (63%); Epsom: 7,567 ft. (18%); Deerfield: 8,100 ft. (19%)
2016 NLWA Budget: $52,400 (Herbicide: $24,900; DASH: $27,500)
