Maine Lakes in the Era of a Warming Climate Zoom Webinar

Many thanks to my friend Ross Swain for promoting this webinar. Ross runs Ellis Pond Sidekicks, a private Facebook group for people interested in Ellis Pond in Roxbury Maine. It’s a great group even if you don’t know where Ellis Pond is 🙂

A week from today Ellis Pond Sidekicks is sponsoring a free Zoom webinar presented by Scott Williams, a renowned lake scientist who has been involved in water quality issues at Roxbury Pond for over 30 years and state lake water issues for over 50 years. The webinar is called “Maine Lakes in the Era of a Warming Climate.” You don’t need to be a member of Ellis Pond Sidekicks to attend. The webinar will be on Friday, April 19 at 6:30pm. If you want to check it out you’ll need to register at this link. After you register, you’ll receive an email confirmation that includes a link to the webinar. The webinar isn’t going to be recorded.

I’ve known Scott Williams for many year and I consider him a personal friend and a valuable teacher, and I’m really looking forward to this webinar.

March 2024 Water Level Chart Archived

3 Clary-Lake-Water-Level-March-2024

March 2024

I have archived the March 2024 water level chart (above, and at left). The dearth of precipitation we saw in February did not continue into March. On the contrary, we ended up with 10.72 inches of precipitation making March 2024 the second wettest March on record, only slightly behind the 11.24 inches received in March 2010. “Normal” March precipitation in this area is around 3.77 inches but we received more than 2.8 times more than that. Even with the lack of rainfall we saw in February, we end the month with nearly 7 inches more annual precipitation than is normal for this date. March was also warmer and windier than usual which resulted in Clary’s ice cover melting off on March 8th, the earliest we’ve recorded since record keeping started in 2001. Continue reading

Upcoming Spring Maine Lakes Webinars

Maine Lakes is putting on a number of webinars this spring on topics of potential interest to friends of Clary Lake. The two that grabbed my attention (highlighted below) are one on PFAS in Maine Lakes and Rivers, and one on Maine’s Newest Aquatic Threats. You’ll find more of interest including a notice for the Water and Sustainability Conference on March 29th on the Maine Lakes website: https://www.lakes.me/ 


PFAS in Maine Lakes and Rivers
Tom Danielson, Maine Department of Environmental Protection
Thursday, April 11 at 5 p.m. Register HERE.

You have probably read about PFAS in the news lately as it relates to contaminated farmland. Tom Danielson of the Maine Department of Environmental Protection will present information about per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals”, in Maine’s lakes and rivers.

Maine’s Newest Aquatic Threats 
Brett Willard and Christine Guerrette, Lake Stewards of Maine 
Thursday, April 18 at 5 p.m. Register HERE.

In early 2023, four new plants were added to Maine’s watch list for potentially invasive aquatic plants. Since their addition, three new infestations of one of these new invaders have been discovered in Maine lakes, with likely more to come. In this webinar the Aquatic Invasive Species team at Lake Stewards of Maine will discuss how to identify these four plants and their native lookalikes, how LSM is engaging with lake communities with active infestations, and how volunteers can become involved in battling aquatic invaders across Maine. 

Clary Lake Ice Out Earliest Ever!

Last-ice-3-8-2024-20240308_142102We have declared ice out on Friday, March 8, 2024. Our records go back to 2001 and this is the earliest date we’ve recorded. The previous record was March 13, 2016. There’s still a little skim ice down in the marsh by the boat launch (likely a result of overnight freezing temperatures) and a few loose floes still in the cove on the south shore in front of David Giampetruzzi’s camp  (it’s always the last to go) but the lake itself was effectively and substantially free of ice by the end of the day Friday. The picture above and at left was taken Thursday afternoon.

Ice out occurred earlier than any of our ice out contest guesses so technically nobody was “closest without going over.” In such a situation, rather than saying “Sorry, no winner this year”  we feel justified in changing the rule to simply “closest” and “next closest” for first and second place which makes Gayle Knight with her guess of March 10th the first place winner of a $25 Jefferson Scoop gift certificate. Some of you will recall that also Gayle won the contest last year. We’re not quite sure how she managed to win our ice out contest two years in a row… she’s either cheating or she’s very lucky. She claims she just really really likes ice cream. We’ll go with that explanation 🙂

Clary_Lake_and_Meadow_Depth_Map_version_1.4Much to his chagrin, Tristan Tabor of Lake Stewards of Maine has come in second with his guess of March 11th. I’ll be mailing him the second place prize, a laminated copy of our Clary Lake Depth Map (pictured at left). Tristan is the Water Quality Program Director, Technical Director, Aquatic Scientist at Lake Stewards of Maine and is a great guy. I can honestly say he is NOT HAPPY to have won any prize at all in our ice out contest, let alone second prize. He is concerned as we all should be at the implications that a warming climate will have on lake water quality.

Clear Evidence of a Warming Climate

Normally, for statistical analysis of climate data one wants data covering as long a period of time as possible. Our ice in and ice out records only go back 24 years to 2001 but even over that short period of time we’re still able to detect a warming trend in our climate, as this chart of ice in and ice out dates shows. You can detect that the average of ice in dates (represented by the straight red line) trends upward ever so slightly, indicating that ice in is on average occurring a little later every year. Likewise, the average of ice out dates (represented by the straight blue line) trends downward ever so slightly indicating that ice out is on average occurring a little earlier every year. However, the number of ice free days (the straight yellow line) is very clearly rising since it’s reflecting both later ice in and earlier ice out dates i.e., it’s being stretched in both directions:

So this brings our 2024 ice out contest to a close. Many thanks to everyone who participated.

Ice Out Imminent (Video)

Ice out is imminent. It is hard to imagine the ice remaining on the south shore of the lake lasting another 24 hours, however we will not call it until we see it. This picture (complete with duck!) shows the condition of the ice along the south shore in Whitefield as of this afternoon. The east end of the lake down to the boat launch is already ice-free and if the wind keeps up this afternoon it will grind the remaining ice up in a hurry. This is the earliest we’ve ever recorded ice-out on Clary Lake. The previous record was March 13, 2016.

Here are couple of short videos:

5 March 2024 Ice Out Update

Steve-Cowles-3-5-2024-IMG_1186The ice is disappearing from Clary Lake even faster than I had thought it would, and judging from the ice out guestimates, earlier than most everyone else too. That said, most everyone thought it would be early this year. Perhaps just not this early. There never was much ice up in the marsh, and what little there was is gone as you can see on this lovely photograph taken by Steve Cowles earlier today (at left and above). You can also see open water on some of the Clary webcams, especially cameras 1 and 2.

If anyone is wondering why we’re using featured images on most all of our posts now, it’s so the post makes it’s way to our Instagram page! If you have what you consider a nice picture of Clary Lake, send it to pictures@clarylake.org and if it makes the cut, I’ll post it here.

February 2024 Water Level Chart Archived

2 Clary-Lake-Water-Level-February-2024

February 2024

I have archived the February 2024 water level chart (above, and at left). There was virtually no precipitation to speak of in February until the last 2 days of the month when we received a total of 1.16″ of rain! We ended the month with only 1.35 inches total, or only 52% of the normal 2.61 inches. On average, February has the least amount of precipitation of all 12 months. Despite the lack of precipitation, the lake level actually fell quite slowly over the course of the month losing only 0.36 feet all month while outflows remained quite high, thanks to January’s excessive rainfall. In fact, for much of the month of February total outflows in acre-feet exceeded those in 2023 which is amazing considering how little precipitation we received. By the end of the 3rd week of February however, outflows had fallen behind 2023 numbers and the lake level finally reached -1.5 feet. With slowing outflows, we decided it was time to add some stoplogs to the weir. The rainfall at the end of the month brought the lake up 4 tenths of a foot, ending the month at -1.09 feet or about average for the end of February. I expect the lake will rise a little more in the  next couple of days. Continue reading

2024 Clary Lake Ice Out Contest!

This is our fifth year running a Clary Lake Ice-Out contest. This year’s prize for first place is the same as last year’s prize, a $25 Gift Certificate to The Jefferson Scoop. Yay Ice Cream! If you guess the correct ice-out date  or come closest without going past it, you’re the winner. It’s quite likely that the ice will go out before the Scoop actually opens for business. As soon as the Scoop opens, we’ll pick up the certificate and get it to you.

In the event there are two (or more) people who guessed the same winning date, the person guessing first (based on the recorded timestamp) will be the winner and the other less-lucky (but still lucky!) person (or persons!) will win a laminated 8.5″ x 11″ Clary Lake Depth Map as a Clary_Lake_and_Meadow_Depth_Map_version_1.4runner up prize (see below). FYI, the earliest the lake has been deemed completely free of ice was on March 13, 2016; the latest the ice has gone out was on April 24, 2001. Last year’s â€śofficial” ice out date was March 29th which was correctly guessed by Vicki Grimaldi. She won a beautiful 12″ H x 15″ W framed loon photograph taken by David Hodsdon. We also awarded some second places prizes to a couple of other people. Visit our Ice In and Ice Out page to see all our historical data back to 2001. Reviewing historical ice-in and ice-out data is NOT CHEATING! We’ll be closing the contest to new guesses late on March 15th or sooner if it looks like ice out is actually imminent. Guess as often as you want, but remember: only your last guess counts!

Here’s the entry form. A few hints: 1) Use the little little calendar icon thingy and select your date guess  by clicking on the calendar, this helps prevent botched dates and 2) I’ll plan to update the list of people’s guestimates at the bottom of this message several times a day 🙂

January 2024 Water Level Chart Archived

1 Clary-Lake-Water-Level-January-2024

January 2024

I have archived the January 2024 water level chart (above, and at left). With an average monthly precipitation of 3.19 inches, January is normally the least wettest month next to February which averages only 2.61 inches of precipitation, usually in the form of snow. This year however we received 3.82 inches or water or 120% of our normal precipitation on top of the whopping 16″ of surplus rainfall we received in 2023. We had to release a lot of water in January from surface runoff from rain and snow melt and also from ground water to keep the lake level down where it belongs this time of year.  We still had water overtopping the dam when the lake rose to within a tenth of a foot of the high water mark on January 14th, an unusual circumstance in January.

Watershed Survey Volunteer Update

The response to our post looking for volunteers (see: 2024 Clary Lake Watershed Survey: Volunteers Needed!) has been good! I’m happy to announce that we’ve lined up a sufficient number of people to assist with the watershed survey this coming spring. That said, it certainly can’t hurt to have a few extra people lined up so if you were on the fence about volunteering for this important project, please consider doing so! There is plenty of work to go around.

Many thanks in advance to the people who’ve signed up to volunteer:

Anya Lagasse, Ashley Prescott, Brian Vogel, Carolyn Curtis, Charlene Andersen, Cheryl Smith, Dave Knight, Dee Ann Grazioso, Eric Sroka, George Fergusson, Julie Cowles, Kathryn Ference, Malcolm Burson, Megan Breece, Michael Keller, Paul Devlin, Steve Cowles, and Wynne Keller.

A Sunny Winter Day

Clary_cam3 casts a shadow on the lake on this clear, cold, sunny day. I don’t really have anything to say, I was just thinking it was time for a picture. I haven’t seen anyone ice fishing, but I heard someone drilling holes with an ice augur yesterday.

2024 Clary Lake Watershed Survey: Volunteers Needed!

clarylake_with_watershedOur Watershed Steering Committee has begun planning the 2024 Watershed Survey, with the assistance of DEP Staff. This is not our first watershed survey, the picture at left is the actual Clary Lake watershed map developed for the 2001 watershed survey. While the watershed itself hasn’t changed in 22 years, a lot of land development has occurred in those intervening years. It is way past time to take this important step in protecting and preserving Clary Lake and its water quality.

The purpose of a watershed survey is to identify sources of non-point source pollution- areas where soil erosion is taking place within the watershed such as along shorelines, gravel driveways, camp roads, road side ditches, dysfunctional culverts, etc. Runoff from rainstorms and snowmelt can result in soil erosion and sedimentation which makes its way into the lake, bringing with it sediment and nutrients, the most damaging of which is Phosphorus.  If you’ve been paying attention over the years, you’ll know that Phosphorus is the primary cause of algal blooms and If we want to keep our lake free of blooms (see picture at the top of this post), we need to reduce the amount of Phosphorus entering the lake. A watershed  survey is the first step in doing that.

Once we’ve completed a watershed survey and have developed a Watershed Plan, we become eligible for Nonpoint Source Water Pollution Control Grants. DEP administers Nonpoint Source (NPS) grants to help communities make progress restoring or protecting waters named as NPS Priority Watersheds (Nonpoint Source Priority Watersheds List). While Clary Lake is not listed as an “Impaired” lake,  it IS on the list of Threatened Lakes, making it eligible for 319 funds- a dubious distinction but an important one! Grants for projects are funded with monies provided to DEP by the U.S. Environmental Protection Agency under Section 319(h) or Section 604(b) of the Clean Water Act.

Volunteers Needed!

We’re going to need roughly 15 volunteers to help with the actual field work of the survey. The plan is to divide the watershed into 4 roughly equal sized sectors and assign each sector to a survey team consisting of 3-4 volunteers and a Technical Specialist who will oversee and guide the survey fieldwork. It is anticipated that the  actual field work will take approximately one day to complete. It will obviously be a long day! Food and refreshments will be provided.

The survey is to take place on Saturday May 4th (rain date, Sunday May 5th). Volunteers will need to attend a Zoom training session held a week or two before the survey. The training will be offered several times to accommodate varying schedules. To volunteer to help with the watershed survey field work or to volunteer in any other capacity on this important project, please email watershed@clarylake.org or call George Fergusson @ 207-242-2256. If you have any questions at all about the survey or why we’re doing it, please do not hesitate to contact us!

CLA Hors D’oeuvre Party Announcement!

It’s never too early to beat the doldrums, or plan to beat the doldrums!! We’re looking to do just that this coming February when we expect the Winter Doldrums to be at their peak! We’d like to gather as many Members as we can to join in celebrating being together, and to break up the monotony and cold of the long winter with some warm cheer and friendly conversation. To that end we’re planning a party on February 24, 2024 at 7 PM at the home of our President, Gareth Bowen and his lovely First Lady Beverley! Their house is down at the end of the long driveway at 739 Gardiner Road in Jefferson in the field overlooking the lake (MAP). Various events have been held there over the years including our first Doldrums party back in February 2020, just before the COVID pandemic started. It was a great party and we’ve wanted to do a repeat of it ever since, and this is the first year when it seems feasible. We hope you can make it!

Mark your calendars!! This party is going happen regardless of the weather, but if there’s a major winter storm underway making travel unsafe or impossible, we’ll put the party off to the following weekend, same time, same place.

Please bring an hors d’oeuvre or light fare dish to add to what is sure to be a smorgasbord of little party delights, and whatever beverage you care to consume. Hope to see you there!

December 2023 Water Level Chart Archived

12 Clary-Lake-Water-Level-December-2023And that’s a wrap! I have archived the December water level chart (at left and above) bringing 2023 to a close. Once again as has happened so often this past year, December rainfall vastly exceeded the monthly average. We received 7.47 inches of rain in December, 4.03 inches more than the average of 3.44 inches. We ended the year with a total of 60.31 inches of precipitation, 16.25 inches more than the annual average of 44.06 inches. To say it was a wet year doesn’t quite do it justice: we got soaked in 2023! All this rain resulted in some wild swings in the lake level in December with it twice rising above the High Water Mark resulting in gentle overtopping of the dam. This isn’t actually all that unusual. Despite our efforts to keep the lake level “down where it belongs” going into Winter, over-topping in December happens roughly 3 years out of 5. Continue reading
