Latest Updates

The Lake Champlain Committee (LCC) and the Vermont Citizens’ Advisory Committee (VT CAC) invite you to the Lake Champlain Community Sailing Center on Monday, 11/13/23 at 5:00 PM to learn more about lake issues and how Lake Champlain was affected by summer floods. Click to learn more! Read...

From afar, a patch of bright green on any body of water is cause for alarm: we are too used to the sight of cyanobacteria plaguing shallow waters close to shore. But get closer to determine what you’re seeing. It may be neither cyanobacteria nor algae, but tiny, individual plants known as duckweed. Read...

In this email you’ll find details of Week 18 monitoring along with information to help you recognize and report on cyanobacteria. Click on the links for scenes of fall blooms on Lake Champlain’s Inland Sea and Missisquoi Bay; a low alert bloom at Burlington’s Coast Guard boat access on Lake Champlain’s Main Lake Central; pictures of the varied conditions witnessed during Week 18 from clear water to high alert blooms; photos of Prouty Bay Lake Memphremagog post-bloom; shots of a high alert at Philipsburg Public Park QC on Lake Champlain’s Missisquoi Bay; pristine scenes at Blanchard Beach and Texaco Beach in Burlington VT on Lake Champlain’s Main Lake Central; autumn observations at St. Anne’s Shrine in Isle La Motte VT, and Burlington VT sites at Blanchard Beach, Oakledge Rocky Shore, and North Beach; and a snapshot of Missisquoi Bay monitor Nancy Lambert in action at her QC site. You can also learn about iron bacteria (and how to distinguish it from a petroleum sheen) and duckweed—which is often confused with cyanobacteria from a distance. If you’re intrigued about duckweed, you’ll find more information about the smallest known flowering plant in the world in LCC’s Lake Look column on our website. Read...

Brrr! It’s getting chilly in and around our waterways as fall fully takes hold. However, cyanobacteria blooms are still happening at various Lake Champlain and inland lake locations. Please use the resources in this email to learn how to recognize, avoid, and report cyanobacteria. Read on for details of Week 17 monitoring results along with resources to guide your reporting. Click on the links for a picture of LCC monitor Alfred Cumming taking a cold water sample, scenes of low alert blooms at Lake Memphremagog’s Derby Bay and Newport Marina and at Lake Champlain sites on Missisquoi Bay and the Inland Sea, and pictures of Lake Champlain clear water at St. Anne’s Shrine, Stoney Point, and DAR State Park.

While reports continue to dwindle as more monitors leave shoreline areas, we continue to see blooms. Please use the resources in this email to learn how to recognize, avoid, and report cyanobacteria. Click on the links for how to join our monitoring team in 2024 and to see pictures clear water conditions at Philipsburg QC and Burlington VT, an autumn alert at Hills Point Charlotte VT, fall leaves amongst cyanobacteria, and blooms at Graveyard Point North Hero VT on Lake Champlain and Prouty Bay on Lake Memphremagog.

Fall is a time of year when we have far fewer monitors reporting but blooms can still occur. This email includes details of Week 15 monitoring results along with resources to help you recognize cyanobacteria and stay informed about water quality. You’ll also find photos of iron bacteria, bloom close-ups from Lake Champlain and Lake Memphremagog, and cyanobacteria sightings at Philipsburg QC, Isle La Motte VT, Alburgh VT, North Hero VT, South Burlington VT, Peacham Pond, and Lake Memphremagog.

Fall is a time of year when we have far fewer monitors reporting but blooms are still prevalent. Forty-three percent of the Lake Champlain reports and 8 percent of the VT inland lake reports we received for Week 14 were of blooms. Please use the resources and photos in this email to help you learn how to recognize cyanobacteria and stay informed about water quality. Read...

Week 13 was a challenging one as blooms took off in new areas and persisted in others and the online reporting system overseen by the VT Dept. of Health (VDH) was not accessible for several days while IT staff worked to resolve issues. This meant monitors had to try to submit reports multiple times and LCC staff had a backlog of reports to sort through and vet once the tracker came back online. Over one third of the 126 reports we ultimately received during the week were of blooms which further reinforces the need to check water conditions carefully even during the fall.

Lake Champlain currently has 51 known aquatic non-native and invasive species of plants, fish, mussels, and other freshwater dwellers. Invasive species are both non-native, or introduced to an area outside the range in which they evolved, and nuisance, or disruptors of the ecosystem into which they were introduced. Zebra mussels, Eurasian watermilfoil, and water chestnut are all invasive species found in Lake Champlain.

Humans have the greatest influence on the spread of invasives—hitchhikers need a ride to get to where they’re going, and humans are highly-mobile hosts that give rides knowingly through deliberately releasing fish into waterways or flushing exotic aquarium plants down the toilet, and unknowingly on watercraft. Fortunately, humans can also play a key role in early detection and spread prevention. That is why the Lake Champlain Committee (LCC) started a new community science project: the Champlain Aquatic invasive Monitoring Program (CHAMP!) with funding from the Lake Champlain Basin Program.

Hints of color are starting to show in the Adirondacks and the Green Mountains as we move into fall. Another dramatic show of color that elicits less awe and more concern has been in the lake between these mountains since early summer—the blues and greens of cyanobacteria blooms.

“Witnessing a cyanobacteria bloom can take an emotional toll,” notes LCC Executive Director Lori Fisher. “Blooms threaten water quality, public health, recreation, the economy, and quality of life. Monitoring is a way for people to get actively involved in lake protection by gathering and sharing data. And that monitoring is not the end result – it’s foundational to LCC’s nutrient reduction advocacy.” Read...

Gardens were not the only places being weeded in August—LCC hosted a water chestnut removal event with the Vermont Department of Environmental Conservation at the Sandbar Wildlife Management Area in Colchester, VT. Volunteers spent the morning paddling the shallow waters north of the mouth of the Lamoille River and pulling up the invasive plant to help prevent it from colonizing the area. Read...
