Mousam Lake & Goose Pond (which cover parts of Shapleigh and of Acton) have an intruder ... their name is Swollen Bladderwort (SB), or more formally Utricularia Inflata. The good news for remediation is that they do not set roots; they float around. Increasing numbers of invasive aquatic plants highlights the reasoning behind Maine's CLEAN DRAIN DRY Boating Law.
We CURRENTLY have volunteers from our out surveying Mousam and Goose Pond to see where we have concentrations of this invasive Bladderwort. Please safely boat around anyone in the water or standing in a boat near the shoreline. If you see someone arrive to your waterfront, go say "hi", meet a neighbor, and know what you can help pull from your waterfront in the future! TY
Mousam Lake is the native habitat for Purple, Common, and Floating Badderwort plants. You can see comparisons of native and invasive plants in our downloadable Lake Dwellers' Handbook, which also offers information about enhancing and protecting our local water sheds. We encourage anyone who enjoys time on Maine's pristine lakes to take a look!

In this video, team members are using an underwater drone to spot SB plants amid the natives. We are assessing deepest and worst spots to assign to a DASH (Diver Assisted Suction Harvester) contractor. Get involved; email [email protected] and ask how you can help!

Plenty of Utricularia inflata here.
