After a warm start to the season, it is finally starting to look--and certainly feel--like winter in the Lake Champlain Basin. To make walking and driving safer in this icy season, state and municipal road crews salt roadways. This practice started in the 1930s, when cars became more commonplace and roads needed winter maintenance. Since then, the annual use of road salts in the US has increased—in the past 45 years, the amount has tripled—to a yearly estimated total of 25 million metric tons.

All of this salt has to go somewhere. When in contact with the water, salt dissolves into its ion building blocks, the most common of which are sodium and chloride. The now salty water first washes off roads, stoops, parking lots, and sidewalks, and it can kill adjacent vegetation quickly, as these species are rarely adapted to high salinity. Salty water then either seeps into groundwater or flows through waterways, winding up in larger reservoirs like Lake Champlain. Chloride concentrations in Lake Champlain and its tributaries have been steadily rising for the past several decades. Read...

In the depths of Lake Champlain, an eel-like creature slithers among the rocks, hunting for a foraged fish dinner. This is no sinister cousin of Champ—this is the burbot (Lota lota), one of Lake Champlain’s only deep-water predator fish (the other one is lake trout). Burbot have a unique look, with small scales forming patterns of blotched green, brown, yellow, and black, all making up their particularly slimy skin. Perhaps their most distinct feature is the single “barbell” protruding from under their chin—think of a long, narrow goatee made of scales rather than hair. They also have large, wide-set, tubular nostrils that protrude from the front of their face, resembling catfish. Read...

Though the days are just starting to lengthen in this new year, winter’s hold on Lake Champlain has really just begun. Lake Champlain does what all water does in cold enough temperatures—it freezes. When record keeping on Lake Champlain freezing began in the 19th century, it was rare for a winter to go by without a complete freeze-over from shore to shore of the lake. This regular freezing created the basis for a seasonal culture of ice-centered activities. Icy activities have been a part of life in the Lake Champlain basin for generations untold, but freezing frequency is expected to plummet due to climate change. Read...

Calling All Paddlers’ – We Want Your Pictures! LCC is seeking boating pictures to enhance our 2023 edition of the Paddlers’ Trail guidebook.

This is a great opportunity to get outdoors and have fun while enriching your curriculum with local, engaging material. Read...

While Lake Champlain is not as cold or icy this winter as it has been in winters of yore, it is still not a place for a casual swim at this time of year. This inaccessibility gives the depths of the lake a certain mystery. What is going on underneath the dark surface of Lake Champlain as winter unfolds? How do fish hunker down and survive what seems to be a hostile environment of icy cold water all season long?

Think about how you interact with Lake Champlain. Do you live near it? Walk along its shores? Perhaps you swim, boat, paddle, fish, or even just skip the occasional stone. Maybe you photograph the sunsets or watch the birds from the shores. Regardless of what you do, your relationship with Lake Champlain is likely even more fundamental than recreation–the lake sustains those who live within its basin. According to the Lake Champlain Basin Program (LCBP), an estimated 20 million gallons of water are pumped from the Lake each day to supply drinking water to about 145,000 people. Chances are, you are using the lake every time you turn on a tap or flush your toilet. The water that passes through you to keep you alive is the same water that flows through the lake–it is literally your lifeblood. Read...

Site coverage is scant this time of year but all 47 reports from Lake Champlain received during week 19 were of good conditions. For inland lakes, Lake Carmi had a low alert bloom and Joe’s Pond had a high alert. The latter covered a wide swath of shoreline but was short-lived. Blooms can still happen late in the season so please continue to report if you’re still in the area. Read...

Only a scattering of monitoring reports are still coming in as we move into stick season but all that do provide important data on water conditions. Lake Champlain was bloom-free for the second fall week in a row. Lake Champlain was bloom-free again for the fourth week in a row. The lone sighting of cyanobacteria came from Lake Iroquois but we only had reports from four inland lakes. Read...

Week 14 of monitoring brought cooler weather, fewer sightings of cyanobacteria, but also far fewer monitors to report them. High alert blooms continued in parts of St. Albans Bay, Lake Carmi, and Lake Morey which have all had persistent blooms during the last weeks or months. Read...

While the weather cooled during Week 13 of monitoring, blooms continued in several lakes or bays where they were present previously and showed up in some new locations. On Lake Champlain, high alert conditions were restricted to nutrient-rich St. Albans Bay but there were low alerts in the Inland Sea, Malletts Bay, Main Lake North, and Main Lake South. Blooms also persisted in Lake Carmi, Lake Morey, and Lake Memphremagog. Read...

Throughout his career in the U.S. Senate, Patrick Leahy has been an unfailing champion for our region's– and the nation's – air, water, and land, and the health of our people. From the Conte National Wildlife Refuge, across the Green Mountain National Forest, to Lake Champlain, his dedication to safeguarding and investing in natural resources has improved our lives. Read...

Blooms continued into Week 12 of the monitoring season. You can see visuals of some of them from Lake Memphremagog, Lake Morey, Tinmouth Pond, Shelburne Pond and Lake Champlain’s Arnold Bay and Valcour Island, and Lake Champlain’s Keeler Bay. You’ll also find photos illustrating blue-green blues and the recreational impact of cyanobacteria. Read...

Several monitors reported odd gelatinous globules in the water at several sites in Lake Champlain’s Inland Sea during week 11 of monitoring. Happily they took water samples and photographs and shared the details with us and our partner Dr. Ana Morales-Williams at the University of Vermont’s Rubenstein Ecosystem Science Laboratory. The samples turned out to be Calothrix sp. – a benthic filamentous cyanobacteria. Read...

Happy end of August! As we move towards September, please remember that blooms can still happen as summer wanes which is why we are only about half way through the monitoring season. Blooms have been witnessed through November in our region during past years and the next few months can be very active periods for blooms. Read...

Conditions at Lake Champlain and inland Vermont waterways were overall much improved from the previous week. Continued warm weather along with the influx of nutrients from periodic storms could trigger additional cyanobacteria blooms so check the water carefully during your recreational outings and take advantage of the resources and links in this email to learn more about cyanobacteria. Read...

Most of the week was sunny, hot, calm, and humid and blooms took off in many Lake Champlain locations as well as at Lake Carmi. Heat waves are known to promote cyanobacteria blooms in waterways by increasing thermal stratification, allowing cyanobacteria to remain in warm and well-lit surface waters, and encouraging release of phosphorus from lake sediments in shallow lakes. Read...
