Variable Milfoil

Weed Watcher Program

The LKWA has decided to take the lead on the Weed Watcher program by volunteering their services this summer. We hope our example will encourage others to do the same. The Weed Watcher Program as described by the Milfoil Committee. "Moultonboro volunteers play a key role in our town’s Milfoil Control Program. Volunteers become the “Eyes on the Water” to spot areas of Milfoil growth. If interested in volunteering you will be Instructed on what to look for and how to conduct a weed survey. Volunteers will also receive a binder full of information on the program and details on the most threatening invasive plants. There is no cost to the volunteer. The only equipment a volunteer needs is access to a boat, kayak, canoe, paddle board, or PWC.”   Lake Host and Weed Watcher Programs work together to prevent invasive species from entering our lake. The Weed Watcher Program may be even more important to preventing Lake Kanasatka from becoming infested because of volunteers constant vigil that is likely to catch infestation before it can take hold.  If you are interested in volunteering for the Weed Watchers program, please contact :

Why should I Volunteer to be a Weed Watcher

Your work could save Lake Kanasatka and your property values......
1. While you are kayaking, canoeing, paddling all you need is to check an area once a week or month from June thru September.
2. If you find a suspicious plant, you give it to Bev Nelson Chair of Moultonboro Weed Watcher Program. She will confirm whether it is invasive or not or she will send it for DNA analysis.
3. There is no cost to you and training and support will be provided. Now what could be easier?
4. Your work could catch an invasive specie before it got a chance to get established.
5. Your work with so little effort can protect Lake Kanasatka and save your property values.

For more about the Moultonboro Weed Watching Program take a look at their informative booklet.

What to do if you suspect an algae bloom on Lake Kanasatka:

  • Notify board members and water quality chair (their email addresses are available here) with the following information:
    • Location of the suspected bloom on the lake (be specific…address, landmarks, etc.)
    • Approximate size
    • Anything noteworthy – when you noticed it, how long it has been there, has it changed, what it looks like (provide photos if possible)
  • Water quality chair will assess and notify both NHDES and UNH Lakes Lay Monitoring Program
  • If NHDES or UNH are not readily available, water quality chair or designee will visit site, take photos, note size, and collect a sample in a 125ml or larger container. Sample will be kept refrigerated and delivered to NHDES or UNH same or next day
  • Water quality chair or designee will follow up with residents and members
Here are some examples of Algae Blooms found in NH lakes.
