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.

Year End Summary of NLWA's Efforts
Below is a summary of the herbicide treatment and DASH diving efforts completed this year:

Herbicide Treatment
Herbicide 2,4-d applied to 28 acres in June 2016.
Total Herbicide Costs: $20,927

DASH/Diver Harvesting
Harvested for a total of 27 days yielding approximately 2600 gallons of milfoil collected.
Total Harvesting Costs: $27,540

Treatment and Harvesting Allocated Costs by Town:

Northwood ($10,000 Municipal Funding in 2016; Requesting $12,500 in 2017):
Herbicide: 26.15 acres treated = $19,462
Harvesting: 13 Days = $13,219

Deerfield ($8,000 Municipal Funding; Requesting sustained $8,000 in 2017):
Herbicide: 1.85 acres Treated = $1,465
Harvesting: 5 Days = $6,233

Epsom ($3,500 Municipal Funding; Requesting $4,000 in 2017):
Herbicide: None. Planned treatment area called off due to loon nesting activity.
Harvesting: 9 Days = $9,088

Lake Host Prevention Program Summary
The NLWA used four paid Lake Hosts and six volunteer Lake Hosts to inspect 748 watercraft over 15 weekends from Memorial Day to Labor Day. The program total cost was $1604.37 with $1300 being provided through a NH Lake grant and $304.37 was covered by private donations to NLWA. Two saves of variable milfoil on outgoing vessels were confirmed by New Hampshire DES this year.

Budget Season is Approaching... Voice Your Concern!
The NLWA will again have warrant articles requesting funding from the towns of Northwood, Deerfield and Epsom. Based on this years data and our projected spend for 2017, we are asking for an increase in support from both Northwood and Epsom. Please contact your Selectmen and/or Budget Committee Members and let them know how important their backing is to our ongoing fight against invasives.

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 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 and we have had considerable success in containing and even reducing the presence of milfoil in affected areas. 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 as well as residents and local businesses to secure much-needed, ongoing economic support... an effort that has been largely successful.

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.
