Weed Watcher Program

The WWN’s Weed Watcher Program draws on volunteers from around the lake who periodically patrol the shoreline and near-shore areas in their location to look for any new, potentially invasive species of plants or animals. The purpose of the program is to identify the presence of any new invasives or new growth of an existing invasive before it gets to be a problem. In our first year of the program our weed-watchers identified several new areas of variable milfoil that were added to the comprehensive milfoil plan.

We hold a Weed Watcher training session each year with staff from the NHDES Exotic Species Program and provide training materials to all of our volunteers.  To learn more about the NHDES Weed Watcher Program click here.

Variable Milfoil

2020 Weed Watcher Campaign

Weed watching on Lake Winnisquam resumed in June and is being conducted monthly along the entire shoreline of the lake.  WWN member Bill Esrich continues to coordinate the weed watcher program for the 3rd year.  Weed watchers:  Click on the button above to fill out the Weed Watcher Report after each weed watching session to let us know that you completed your monthly survey and if you found a suspiscious plant growth or animal.   


2019 Weed Watcher Campaign

This year’s weed watcher program kicked off on June 1st with another training session held by NHDES for both new and expereinced weed watchers.  With the addition of new weed watchers this Summer we now have coverage for the entire shoreline of Lake Winnisquam.  All weed watchers began their surveys in June, and will continue monthly through August or September, depending on availability.


2018 Weed Watcher Campaign

The 2018 weed watcher program was a huge success.  WWN wants to thank all who participated in the program, and Bill Esrich for coordinating the program this past season.  We started the season with a training session in early June, and 33 volunteers patroling 24 areas around the lake on a monthly basis. An additional 8 people volunteered mid-summer for the 2018-19 season.  The entire lake shoreline was patroled at least once, and most areas were checked June through September.

There were five new areas of milfoil discovered by our weed watchers that were subsequently removed using diver-assisted harvesting :

  • Durgin Brook
  • 2 locations along Stoney Brook Road
  • Leighton Ave
  • Chapman Brook

We also want to thank Amy Smagula, ProgramCoordinator at NHDES,  for the many weed identifications and the quick responses to all of our inquiries.  The program was a tremendous success.  Without it, the new areas of growth could have continued to spread unmanaged.
