Water Quality Technical Support Sessions

Friday, 10/4 at 12:30


Open to certified volunteers and the public. Do you have questions about what you are seeing on your lake or other? Are you curious how the impacts of climate change are being felt? Is your lake experiencing seasonal inversion already? Does your data seem weird this year? These are all excellent reasons to join us and discuss what is happening around the state.

We are in the season of lake turnover meaning nutrient-rich cooler water 🌊 and warm waters are mixing. Ephemeral algae blooms are more common when this happens. Please take photos 📸 of any potential cyanobacteria you see and let us know by emailing us images of what you see or use the EPA BloomWatch app to submit the images.

This week's community update

Mousam Lake Survey 9/18


On Wednesday, September 18, Lake Stewards of Maine staff and volunteers visited Mousam lake for a swollen bladderwort infestation monitoring survey.


Members of the IPP Travel Team, with volunteers from Square Pond, Spaulding Pond, Little Ossipee Lake Association, Lake Arrowhead, Panther Pond and others, assisted Mousam Lake Region Association with the survey. Together the survey team, consisting of 17 staff and volunteers, patrolled high-risk areas of Lower Mousam Lake, marking any occurrences of the invasive plant. Mapping the infestation will help with future management efforts, including hand-pulling and Diver Assisted Suction Harvesting (DASH), which have been underway since its discovery.


Swollen bladderwort, an invasive plant discovered on Mousam in 2023, has been confirmed in seven lakes since its addition to Maine's aquatic invasive species list last year. It strongly resembles native bladderwort species, but has key morphological distinctions that help it stand out to its native lookalikes.


We thank our volunteers for their hard work during this survey.


To be involved in future opportunities assisting LSM's IPP Travel Team, or receiving our latest news please use the link below.


To learn more about swollen bladderwort and its native lookalikes, please watch the "Know Your Bladderworts" webinar using the link below.
