July 24 and wind is still a hinderance. I patrolled Paige Brook for the second time this season. First patrol was in June. All the usual suspects (not suspicious) and more of it since June patrol. Pickerelweed, bur-reed, Pipewort. White, pink and yellow waterlily, floating heart. Bladderwort, native naiad, pondweed, native milfoil and several grasses. Patrolled the channel while conditions were favorable from Gloria’s and around the shore toward boat launch to other shore bac

Paddled Zone 2 today and all looked good. Noted lots of submerged blobs/clouds of filamentous green algae. These create bubbles of oxygen and if trapped in the algae it will float to the surface of the lake. See photo below. Made a detour from my patrol to photo the north shore loons and chick. Filamentous Green Algae Native Water Naiad - can be distinguished from the invasive form by the smooth edges of its leaves.

Bladderwort

I was out for a paddle this past week through Turtle Cove in Zone 1 and spotted this nice example of Floating Bladderwort (Utricularia inflata). There are four types of bladderworts that have been identified in Conway Lake, and this is the least common form. There are two quite different types of leaves on Floating Bladderwort. The lower leaves alternate on the stem, are up to 3 cm long, and are divided many times into hair-like leaflets, each bearing many tiny bladders.

July 18, 2026 First AIS Patrol of Zone 11 this morning. Weather was perfect, winds calm, and light was good. I stayed in Zone 11 to get a more thorough look at what's growing. While seeing nothing invasive, white and yellow pond lily (much in bloom), Potamogeton natans (pond weed), bladderworts (Utricaria spp) including thin-leafed, floating hearts (Nymphoides cordata), watershield (Brasenia schreberi) with its gooey underside, and tape-grass (Vallisneria americana) were all

'Avenza', the mapping app that served us so well in tracking our patrols, is now charging a fee to download custom maps. You will find that if you try to use it, it will no longer allow you to download and use the AIS Zone map of the lake. You can however use their generic basemap to track your path on the lake. To use the app and download the AIS map you now have to pay an annual fee of $35. I've opted to pay the annual fee but if you prefer you can use the free version

The lake is warming up, and aquatic plants are beginning to take off. It’s time to pull out your gear and reacquaint yourself with the native plants in Conway Lake, as well as the invasive species we are watching for. I patrolled most of Zone 1 this past week and noted many floating aquatic plants, including water lilies, watershield, floating burr-reed, and floating pondweed, as well as lots of submerged grassy spike rush, two large patches of native Elodea (doted circles on
