Happy Friday! Lots of green dots populated the cyanobacteria tracker this week and reports of clear water, non-filamentous green algae, and iron bacteria dominated over cyanobacteria in most areas. However, we did have cyanobacteria bloom reports from Lake Carmi and Lake Morey as well as Lake Champlain’s Inland Sea and low and high alert conditions at several St. Albans Bay sites as of today (8/20/21). Read...

Cyanobacteria monitors kept us busy again this week with 136 Lake Champlain reports and 43 from inland waterways. Blooms occurred in the Lake Champlain’s Inland Sea, Main Lake North, Malletts Bay, and St. Albans Bay as well as Indian Brook Reservoir and Lake Carmi as of this writing. Read...

We had many clear water reports early in the week but conditions changed in some areas as the temperatures rose and the air stilled later in the week. A bloom took off in St. Albans Bay, and alert conditions were witnessed elsewhere on Lake Champlain, Lake Carmi, and Lake Memphremagog. Read...

Happily water conditions improved significantly this week! Roughly 85% of the Lake Champlain reports and 94% of inland waterway reports showed generally safe conditions. Read...

Another busy week of monitoring with variable conditions up and down Lake Champlain. While most monitors reported generally safe conditions at Lake Champlain and inland waterway monitoring sites, low and high alert blooms were in evidence too. Lake Champlain’s St. Albans Bay, Inland Sea, Malletts Bay, Main Lake North, Main Lake Central, and Main Lake South, along with Indian Brook Reservoir and Lake Carmi, all experienced cyanobacteria blooms. Read...

Lake Champlain Committee (LCC) and community monitors filed a total of 246 reports this week as blooms showed up in a host of Lake Champlain shoreline and inland lake locations. Escalating temperatures spurred cyanobacteria growth that closed beaches at several lakeshore communities. Read...

Although generally safe conditions still dominate on the cyanobacteria datatracker, blooms showed up in several sections of Lake Champlain and Lake Memphremagog this week. Read...

While we received some reports of low alert cyanobacteria conditions on Lake Champlain and Lake Carmi, the majority of monitors observed generally safe conditions during this second week of the 2021 monitoring season. The cyanobacteria datatracker is populated with lots of green dots again this week. Yay! Read...

Monitoring began this week and will run through early fall. This week’s report covers conditions from Sunday, June 20 through early-afternoon on Friday June 25. The vast majority of reports we’ve received to date indicate generally safe conditions. Yay! Read...

Cyanobacteria blooms: Why do they happen, what are the risks, and what can we do?

Cyanobacteria blooms have received increasing attention in recent years, as a result of

particularly strong blooms in some areas. As research into blooms continues, we learn

more about what things make cyanobacteria blooms more likely, what dangers blooms

can pose to humans and other animals, and what the future might hold.

We weren’t sure how many people would turn out to monitor during a pandemic that required wearing a mask at public sites and quarantining for two weeks if traveling across state lines. But turn out they did! More than 160 community members signed up to check conditions at over 150 Lake Champlain and inland waterway locations during the 2020 season. They included returning veterans, first-timers, seasonal and year-round residents, couples, families, students, and friend groups. They took on more rigorous protocols, showed up virtually for training sessions via Zoom, and faithfully filed weekly reports. Read...

We send heartfelt thanks to Angela Shambaugh, our longstanding cyanobacteria monitoring program colleague who retired in October from the Vermont Department of Environmental Conservation (VT DEC). Angela has been a key partner in the monitoring program since its inception in 2003. In the early years she assisted in lab analysis, cyanobacteria assessments, water sampling, and community outreach while working at the University of Vermont. Read...

While the cyanobacteria tracker map was dominated by green dots last week, too many red dots evidencing blooms are showing as we head into Labor Day weekend. While good conditions were observed at Lake Champlain’s Malletts Bay, Main Lake South, and South Lake and at numerous inland waterways, cyanobacteria blooms showed up in Missisquoi Bay, St. Albans Bay, the Inland Sea, Main Lake North and Main Lake Central on Lake Champlain as well as at Lake Carmi, Lake Morey and Shelburne Pond. Blooms can pop up or persist well into the fall so please continue to check conditions carefully whenever recreating near waterways. Read...

Monitors filed 151 reports this week from Lake Champlain and inland lake sites. The cyanobacteria tracker map shows lots of green dots this week for generally safe conditions. However, blooms are still present in some areas of Lake Champlain and inland lakes. Read...

It’s been a tumultuous week with hot weather, intense rains that flushed nutrients and partially treated wastewater to Lake Champlain, and some high winds that knocked out power. In the midst of it all cyanobacteria monitors collectively filed 212 reports from Saturday August 8 through 1:30 p.m. on Friday August 14! Read...

The Lake Champlain Committee (LCC) and partners received 186 monitor reports last week from August 1 through 4:00 p.m. Friday August 7, 2020.

Thank you for signing up to receive the Lake Champlain Committee’s (LCC) cyanobacteria monitoring reports! Monitoring will run through the early fall. Each week we’ll send you an update about conditions our monitors are finding around Lake Champlain and several inland lakes. This week’s report covers results from Sunday July 5 through late afternoon Saturday July 11. We had 159 reports that ranged from clear water conditions (perfect for cooling off in) to turquoise blooms that closed down access areas. Future reports will generally be sent to you on Fridays. Read...

Photosynthetic bacteria, gelatin, and concrete are the building blocks of a new type of material: living concrete! Researchers at the University of Colorado, Boulder, funded by the Department of Defense, formed the new substance. Minerals in the concrete are deposited by cyanobacteria; in contrast to the typical greenhouse gas-emitting process required in the production of regular concrete, cyanobacteria absorb carbon dioxide through the photosynthetic process.

Hundreds of LCC-trained volunteers took to the water from mid-June through mid-November to assess conditions at more than 100 Lake Champlain and inland waterway sites. Each week they scoured the shoreline for signs of cyanobacteria, donned gloves and took water samples and faithfully filed online reports.

This is the last report of the 2019 Lake Champlain and Inland Lake cyanobacteria monitoring season. Lake Champlain Committee (LCC) monitors and partners have filed over 2,700 reports from Lake Champlain and inland lakes during a 22-week season. We’re deeply grateful for their efforts. Read...

It’s snowing in the Lake Champlain Valley, coating much of our region in a gentle blanket of white as we enter our last weeks of cyanobacteria monitoring. The cooler temperatures make conditions much less hospitable for cyanobacteria, so not suprisingly, the majority of reports this week were for generally safe conditions. However, the bottom-dwelling cyanobacteria, Nostoc sp., was observed again at Lake Winona earlier in the week. Read...

Cyanobacteria blooms were reported this week from Lake Champlain’s St. Albans Bay, Inland Sea, Main Lake North, Main Lake Central and Main Lake South as well as at Lake Carmi and Lake Memphremagog. Yesterday’s intense rain may wash cyanobacteria out or give them a fresh load of nutrients to grow. While the cooler temperatures will make conditions less hospitable for cyanobacteria, they may still pop up so please use the links and resources in this email to help you recognize, avoid and report blooms. Read...

Blooms were observed this week at a few Lake Champlain locations as well as on Lake Memphremagog. Temperatures are predicted to stay fairly warm into the beginning of next week, so cyanobacteria may continue to show up in waterways. As you enjoy fall’s beauty in the watershed, please keep a close eye on the water and use the information and links in this email to learn how to recognize, avoid, and report cyanobacteria. Read...

Blooms were experienced this week in Lake Champlain’s St. Albans Bay and Main Lake North, as well as Lake Carmi and Lake Memphremagog. We’ve had a blustery few days, with strong winds triggering lots of wave action on our waterways. In addition to breaking up existing surface accumulations, the windy weather and power outages also affected some monitors’ ability to report. Read...

We had some great weather for leaf peeping this week but unfortunately, those moderate temperatures and sunny, calm days also helped cyanobacteria blooms flourish. High alert or mixed conditions were witnessed in Lake Champlain’s St. Albans Bay, the Inland Sea, Malletts Bay, Main Lake North, Main Lake Central and Main Lake South as well as in Lake Carmi and Lake Memphremagog.
