We must all be stewards of

Maine’s precious lakes.


Education is an ongoing process - there are never too many opportunities to raise awareness.


Check out Tristan's thoughtful op-ed on the impacts of aquatic invasive species.

Do you know of any groups or associations involving paddlers, anglers, Maine Guides, or boaters? Please share their contact information with us so we can connect with them and grow our volunteer network.

Water Quality Program

Attention! Water Quality Data Due


✅ All completed water quality datasheets are due September 15. Please send in additional datasheets when you complete your sampling season.


✅ If you have submitted the data using Survey123, please note it on the form in the appropriate location (column / bottom right) AND send the completed datasheet to us.

Fall Cyanobacteria


As summer transitions to autumn, more precipitation falls and lake waters mix. This can lead to abundant nutrients that allow some algae, including harmful cyanobacteria blooms, to grow. Please be on the lookout for significant globs of algae in the water, scums, and what can appear as spilled paint. Click here to see some examples of cyanobacteria blooms. If you see these, please take photos and let us know, your observations are crucial!


Take a photo, capture a sample in a clean glass jar (store in fridge), and report using EPA's BloomWatch!

Next AIS Tech Session

Tuesday, Sept 9 - 1 pm


Join the Aquatic Invasive Species for the last AIS Tech Session of the season. This is an open session to talk about suspicious and invasive species, aquatic plant identification, IPP survey methods, collecting data, and ask questions.

NEAPMS PLANT CAMP


Lake Stewards of Maine had the pleasure of co-sponsoring and presenting at the North East Aquatic Plant Management Society's (NEAPMS) Plant Camp event this week from September 2 through September 4.


The event drew volunteers and professionals in the aquatic invasive species and lake management sectors from New Jersey to Maine. Held at the YMCA Camp of Maine at Cobbosseecontee Lake, the three-day program was filled with lectures, hands-on workshops, and paddle expeditions led by AIS experts from around the country. 


Lake Stewards of Maine helped co-sponsor the event, and each participant received a complete copy of LSM's Field Guide to Invasive Aquatic Plants and a copy of our Quick Key. Additionally, LSM AIS program staff members Brett Willard, Christine Guerette, and summer intern Naomi Zeidenberg led presentations on aquatic plant identification and working with volunteers, and assisted with on-water plant paddles at Cobbosseecontee Lake and Upper Narrows Pond. 


During the week, campers also heard lectures and attended workshops led by staff from our colleagues and partners at 7 Lakes Alliance, Maine Department of Environmental Protection, Maine Natural Areas Program, and LSM Board of Advisors members C. Barre Hellquist and Ken Wagner. Guests were also able to see over one hundred samples of aquatic plants from around the northeast in an advanced plant ID station.


LSM would like to thank the Maine Department of Environmental Protection (DEP) for their work in organizing Plant Camp with NEAPMS, and for including LSM in the planning process. We also would like to thank all of the guests, who traveled across the northeast to attend and visit Maine for this unique and special event.

Invasive Terrestrial Plant, Be on the Lookout for...


LSM specializes in Aquatic Invasive Plants, but it is good to be aware of other threats to our landscape. Our friends at the Department of Agriculture Conservation and Forestry are concerned about Japanese Stiltgrass (Microstegium vimineum). This highly invasive 1' to 3' tall grass has reflective hairs along midrib of its alternating leaves and causes significant harm to the ecology of Maine. Please be on the lookout for it and find out more here: https://www.maine.gov/dacf/mnap/features/invasive_plants/microstegium.html


How You Can Help:

Residents are asked to stay alert, especially in July and August when the plant is easiest to spot. Look for:

  • Smooth, pointed leaves (2–4 inches long) with a shiny silver stripe down the middle
  • Shallow roots that make the plant easy to pull up
  • Reddish stems later in the season
  • Seeds forming in September–October that resemble crabgrass
