In October, 2021, a new invasive plant was found blooming in Lake Arrowhead in 3 slow moving, shallow coves. It’s called Utricularia inflata (swollen bladderwort), a carnivorous, free-floating (therefore unrooted) aquatic. It resembles a native bladderwort we have in our lake, Utricularia radiata, which is much smaller and more delicate.

This is what the invasive plant looks like (it can flower through till November):

The natural range of this plant is the southeastern coastal plains of the U.S. This is the first confirmed record of the plant in Maine. It has been documented in Connecticut and Massachusetts. It is easily spotted when in flower, so finding it at this time is not dependent on water clarity or turbidity. If you see  such a plant in your cove, please email or message me at, or 207 6191301. Alternatively, alerting a LACC board member would also work.

It has floats that hold the flower up out of the water :

This find, and that of the invasive Najas minor last year, highlights the absolute necessity of meticulously checking, cleaning, draining and drying watercraft when entering and leaving our lake.

October 7, 2021 – Laurie Callahan, YCIASP Founder & Coordinator 

This is announcing the rescheduling of some invasive aquatic species (IAS) awareness-building opportunities. I would like to invite you to join me this Saturday, 10/9, for visits to 3 river sites of interest – in regards to IAS presence and current projects. Join me for one, two or all three. These visits will not be on-the-water, but will be via viewing from the shore or wading in relatively shallow sites on the Salmon Falls River and Little Ossipee River. 

Short descriptions, locations and times of the 3 site visits are provided below. 

Please let me know if you plan to join me. If there is a need to cancel, revise the schedule, etc. I will want to be able to contact you. The sites we will visit are relatively shallow, and if you plan to join me please wear shoes that can get wet, or bring tall boots or waders. Just being on shore will be OK too. 

Will look forward to seeing some of you on Saturday! 

If you cannot join me, please pass the invitation along to others that might be interested.

Laurie Callahan, YCIASP Founder & Coordinator 

(mobile: 802-258-1877) 


Here are short descriptions, locations and times of the 3 site visits: 

#1  Little Ossipee River, below the Balch Lake dam on Acton Ridge Rd., Acton/Newfield (ME); 10:30 AM, Saturday, 10/9/21; meet at pullover across from dam. YCIASP has set-up screens in the river to capture variable milfoil fragments being carried by water flowing over the dam from Balch Lake. Variable milfoil has been present in Balch Lake, and other waterbodies upstream of it, for over a decade. The river and other waterbodies downstream from this site are very undeveloped and relatively remote – and vulnerable to colonization by the variable milfoil fragments travelling downstream. 

#2  Little Ossipee River, Limington (ME), at the intersection of Doles Ridge Rd. and Rte 117; 12:30 PM, Saturday, 10/9/21; meet at dirt parking area at the intersection, on river side of Doles Ridge Rd. This site is about 1.5 miles below Lake Arrowhead, where variable milfoil is well-established. This location is a good site to see variable milfoil that has become established in the river below Lk Arrowhead. 

(If there is time and interest, we may also visit a location directly below the Lake Arrowhead dam on New Dam Rd. in Limerick. In 2020 N. minor was discovered growing in Lake Arrowhead, just above the dam. We may do a cursory check for growth of N. minor below the dam.) 

#3  Salmon Falls River, Lebanon (ME) just below the Spaulding Pond dam; 2:30PM, Saturday, 10/9/21; at the intersection of Spaulding Ave., River Rd. and Indian Lake Drive. Roadside parking on River Rd. We will view invasive variable milfoil growing in the river at this location and will also check for the presence of European water nymph (Najas minor). Both of those invasive aquatic plants are present in Spaulding Pond. (N. minor is also present in Townhouse, Depot and Northeast Pond, just up the Salmon Falls River from Spaulding Pond.)

July 29, 2021 – Invasive Plant Paddle session presented by the Lake Stewards of Maine

Attendees learned how to determine if a plant they find is one of the eleven Maine invasives. They also learned how to tell the invasive Naiad from the two other Naiads we have in our lake.


July 8, 2021 – Lake Arrowhead Kayakers and Canoeists– Please get involved in this important project. 

The Plant Paddle on July 29 has been announced by LSM!

Free Invasive Aquatic Plant Paddle session for Lake Arrowhead

The Lake Stewards of Maine (LSM) will be presenting a Plant Paddle on Lake Arrowhead in July. Plant Paddles provide a fun, informal way to learn about the threat of invasive aquatic plants and the importance of early detection. All attendees will receive (and learn how to use) LSM’s waterproof, tear-resistant “Quick Key” to quickly determine whether or not any plant found growing in the lake is suspicious. We will collect samples of native aquatic plants, observe samples of the invasive plants that are known to occur in the lake, and practice skills needed for local invasive aquatic plant survey efforts.

Pre-registration is required

Thursday, July 29, from Noon – 3:00 PM


(Address and directions will be provided once you have registered)

A light lunch (hamburgers) will be provided. People who have dietary restrictions or preferences should pack their own lunch.

If you are interested in learning how to identify our new invasive species Najas minor, please register here to attend.

June 29, 2021 – the first fragment of this year’s growth of the invasive naiad was found in the vicinity of the dam section of Lake Arrowhead.



We need your help in locating the areas it’s growing in. Please keep an eye out, and report sightings or look-alikes to or 207 619 1301. There are plant collection containers at each clubhouse where you can leave a sample that may resemble this plant – let Debbie know when she should collect a plant.


June 25, 2021 – update posted on front page.

From President Mike Fitzpatrick

Hi LACC Members:

Just wanted to give you an update as we wrap up our first week of full operations in both the DASH and CBI programs.  CBI inspections started on Monday at the Ledgemere DAM boat ramp.  Inspections will be manned 7 days a week at that location at least through the Labor Day Weekend.  We also will have an inspector at the Bay Cove LAC Members Only Boat ramp on Saturdays and Sundays.


The DASH program did get a jump on our normal season start.  We were fortunate to have enough DASH crew available to run one boat since the middle of May where we concentrated on member beaches, boat ramps and some Pay for Play programs.  We started this past Monday with both DASH Harvesters out and have been filling the baskets and barrels daily.  I’ve included pictures for our website.  But the big news is LACC has hired its first female boat captain this year!  We’d like to welcome Captain Charlotte Sanfason to our team.  Charlotte has grown up on our lake and has a love for the lake like all of us do.  Some of the pictures show the diver prepping to enter and the full face mask that is utilized with communication equipment.  There is one picture with Capt Charlotte and the second diver with the head gear on. She keeps in constant communication with the diver on the bottom at all times.  It’s not easy work as you see the Captain transferring the milfoil into the large cage basket and barrel from the receiving basket.  The divers split the day between active harvesting below and the communication/safety role on the topside.


Finishing this up now so I can run off to meet with John McPhedran, the head of the Maine DEP Invasive Aquatic Division. We are going to review the current growth level and discuss future plans.


Have a great weekend.. Hope to see you on the lake….


Mike Fitzpatrick



Variable Leaf Milfoil 

From member Deb Broderick (June 2021)

The stalks you currently see growing at the water surface above the patches of milfoil are the flower bracts that are used for sexual reproduction.

Pictures taken by member Deb Broderick (early spring 2021)

These pics show clear root growth on fragments found right after ice-out this year. It’s always worth removing detached floating fragments from your waterfront. “On the second day of ice-out this year (2021), I found a few floating fragments of Variable Milfoil in my cove.  I fished them out with a long net and could see new roots on the weathered stems, so they were still viable, right after the winter. It’s better to monitor the shoreline and pick them out now before they root and take hold.”
