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...

Good water conditions dominated monitoring reports for the third full week of fall but there are far fewer monitors reporting this time of year on Lake Champlain and inland lakes.

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...

We’ve had a lot of additional subscribers to our weekly cyanobacteria emails so here’s a link to all the weekly reports from the 2022 season in case you’ve missed any of them. They’re worth checking out for the compilation of reporting results, visuals of blooms, and information to help you differentiate cyanobacteria from other lake phenomena. Read...

Happily, Central Main Lake was bloom-free during week 8 of monitoring but blooms persisted in sections of St. Albans Bay and Missisquoi Bay on Lake Champlain and Lake Carmi. After a week of bloom-free reports, cyanobacteria was observed again on Lake Memphremagog. Read...

Bloom reports for the week were restricted to the Central Main Lake, St. Albans Bay, and Missisquoi Bay on Lake Champlain and to Knapp Pond and Lake Carmi for Vermont inland lakes. 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...

It's the season when cyanobacteria blooms are most prevalent. Learn how to recognize them by viewing this video produced in partnership with the Lake Champlain Committee (LCC). Read...

Our week 4 cyanobacteria monitoring report for July 10 through July 16 was delayed due to a breakdown with the cyanobacteria tracker.

The Lake Champlain Committee (LCC), Conservation Law Foundation (CLF), and Vermont Natural Resources Council (VNRC), have jointly filed a petition requesting that the Environmental Protection Agency (EPA) either force the State to correct its failed administration of the Clean Water Act or step in to regulate clean water enforcement in Vermont itself. Right now, the state’s Agency of Natural Resources and Agency of Agriculture both oversee clean water regulation on farms, a situation which leads to confusion and mistrust among farmers. Read...

Vermont is becoming warmer and wetter due to climate change. Specifically, the Vermont Climate Assessment 2021 notes that both summer and spring precipitation have increased in the Green Mountain State. The Assessment cautions that “[t]his spring precipitation . . . can make farm operations difficult.” Read...
