Zone 7 … Out to the Farthest Buoy and back
John Edgarton (hearty soul that he is) took out his kayak on August 22nd and patrolled from his dock in zone 6, grid #172, to Gull Rock, Maidens of the Mist and out to the farthest buoy (grid 173) and back. He stated that his Avenza map would not track and he wanted to report the patrol through me. He found that there was surprisingly very little plant growth around any of the rock collections along that stretch. He is remembering that in past seasons there was never a lo

It’s even BIGGER in zone12 than we had imagined!!
Kay, my 10yr old grand-daughter, and I made it back to Pennacook on 8/20 and to the big boulder in grid #429 to investigate the Bryozoan we reported on in an earlier post this season but did not have either the sun or my camera to record it fully. We knew that it was large, but this is just huge. Kay’s hand as you see it, measuring 6” at its full length, made the full length of the fetus-like shape be about 12” long as we looked down on it … then I managed to wrap ¾ of my

Surprising finds in Zone 7
Aug 15th had started off a sunny day with no wind but that only lasted until early afternoon, snipping short the patrol. Regardless, some neat finds were made. My grand-daughters Benna and Kay, ages 9 and 10 respectively, came with me and were determined to see whatever I saw, know the names of the plants I pointed out, and then investigate further if possible. They did just that. Inspiring. Each one had their own inflatable paddle board and, after about few minutes of thei

Easy viewing over zone 15
Aug 15th was exceptionally sunny with absolutely no wind which made viewing to the lake floor almost effortless. No new news of any changes with the plants I found earlier in July (other than I remain amazed at how substantial the clump of Elodea is in grid # 474.) No new plants to report.

A FIND … nope, Two of Them !!!
Aug 6th in Zone 7, grid 200, my 10yr old granddaughter and I, armed with AIS plant guides, we climbed onto my paddleboard and took off to search for and identify any plant growths either growing on the lake floor or floating along the shoreline that we might encounter. We started off finding: Spiral pondweed bits crowded up against one of our dock support posts. Pipeworts, with no flowers, right off our shore that we dug up and investigated to confirm that they were not Quill

A Great Learning Curve
On Aug 4 Cheryl Cullion and I met at South Cove (her chosen zone) for her first run through on how to patrol using the system that we have all developed. That day was right after a strong burst of rain a few days before which left the water in the immediate coves around Snow Brook so full of dirt particles that it was virtually impossible to see to the floor of the lake. But along the shallower areas we found Filamentous Algae, Tape grass, Floating hearts, Watershields, Ribbo

Some impressive finds in Zone 14; very little at top of Zone 13
July 26th offered another morning of bright sun and calm waters that just had to be taken advantage of. I headed out and even tried my hand at dropping some pins during the patrol to mark where I had some interesting finds...outside of the first one I was almost on target. The second and third landed almost on top of each other. (More practice needed.) The aquatic plants I found in Zone14 offered few surprises. That said, given it is relatively early in the growth season, I f

Interesting finds in Zones 15 & 16
July 25th and patrolling another sunny morning with very calm winds – so perfect. Started at bottom of Zone 15 and found nothing unusual other than in grid 485 where there is still the amazingly thick layer of Aquatic Moss, now at least over 1.5’ in one section. Scattered within the moss was a good mix of Elodea, red Water Naiad (pic attached), Thin-leaf Pondweed, and wispy strands of Floating bladderwort. Naturally, a fine coating of Filamentous algae was everywhere. Met up

Zone 7 Looking Pretty
July 24th was finally a sunny day with calm winds(!) Throughout the zone I found the water was a combination of easy viewing to the lake’s floor and very fine dust or debris on the surface with a good many floating strands of young bladderwort, thin leafed Pondweed, Elodea, and/or native Water naiad. The Maidens of the Mist and Gull Rock had barely any plant growth that was visible but there were the familiar bright green Fresh Water Sponges of previous years, stuck to many

Flowering Floating 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.

S. Cove - Zone 11 - First Look of the Season
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
