Weed Watcher Program ID's and Helps Eradicate Aquatic Invasive Weeds

The Weed Watcher program is a State of NH Dept of Environmental Services program to identify aquatic invasive weeds and animals, prevent their spread, and coordinate eradication.


What Weed Watchers Do - Invasive plants and animals

Each Weed Watcher checks a section of the lake monthly from June to September. So far in 2018 there have been no invasive plants found on the lake bottom. However, Common Reed (Phragmites) shoots were found and cut down at the common lot between the Cahill's and Donovan's. Monitoring and plant removal will continue.


What You Can Do - right from your shoreline

We have received further information from the State DES about invasive aquatic animals such as Asian Clams and Chinese Mystery Snails.


We ask lake residents to watch for these invasive aquatic animals as well as plants along your shorelines. Look online for photos of aquatic invasive species to identify them.  If you see a suspicious-looking plant or animal, contact Evie Conroy or a Weed Watcher team member.

Common Reed (Phagmites) Eradication Report - Sept. 4, 2014

Brad Caswell's Common Reed Eradication project summary and recommendations are available here. A good read on a critical project.


Common Reed (Phragmites) Eradication Project History

The first phase of Common Reed eradication by an outside company took place in September 2012 as planned. A second area has been identified nearby and will be handled as a separate project, and Brad Caswell is overseeing both. The Common Reed infestation was first positively identified in 2009 by the Department of Environmental Services (DES).


Eradication by hand (!) began in the fall of 2011 in an area on the eastern shoreline where a highly invasive exotic weed, the Common Reed, had taken hold was was spreading well beyond the original area.


In early 2012 LAA board hired a company specializing in weed eradication to eliminate the Common Reed (Phragmites) over a three-year period costing several thousand dollars.
