In late October Lake Champlain Committee (LCC) community science volunteer Ashley Leemans tossed an aquatic rake into Lake Champlain and pulled in a clam while doing a routine monitoring check for aquatic invasive species (AIS) at the South Bay Boat Launch in Whitehall, New York. Ashley immediately reported her finding complete with photos to LCC and we followed up with the Lake Champlain Basin Program (LCBP) and state agencies who conducted further analysis and confirmed our suspicions that the mollusk was golden clam (Corbicula fluminea). The aggressive AIS has been documented in the region since 2008, but the October 2024 sighting is the first known finding in Lake Champlain. Native to the eastern Mediterranean, Asia, Africa, and Australia golden clam is hermaphroditic, meaning a single individual can start a new population. The species is known to reproduce quickly in other North American waterbodies. Read...
When a volunteer pulled a suspicious clam from the lakebed in Whitehall, New York, as part of a routine monitoring program last month, they immediately reported the find to lake scientists. Further analysis confirmed the first known occurrence of invasive golden clam (Corbicula fluminea)in Lake Champlain. The volunteer, working with the Champlain Aquatic Invasive Species Monitoring Program (CHAMP), made the discovery while conducting a survey at the South Bay boat launch.

We have a far smaller cadre of community science volunteers checking monitoring sites this time of year so while we’re still receiving bloom reports our coverage both on Lake Champlain and inland waterways is greatly reduced. Read...
Lawns make up a large portion of the developed area in the Lake Champlain Basin and simple changes to mowing and fertilizing practices can reduce stormwater runoff and pollution. Although lawn maintenance tends to wind down this season, fall is an important time to consider practices that reduce water quality impacts and can improve the health of your lawn and soil for next summer and beyond.
Read on to learn about what you can do on your lawn to support water quality! Read...
The cooler fall temperatures reduced the number of bloom sightings but we also have far fewer monitors reporting this late in the season so blooms could have been missed due to lack of coverage. Read...
Over a third of the 91 monitoring reports received for Lake Champlain during week 16 chronicled blooms--only the Main Lake South and South Lake segments had no blooms reported. Lake Carmi and Shelburne Pond also had reports of blooms. While the season is winding down, cyanobacteria can still show up long into the fall. Read...
The number of monitoring reports received for Lake Champlain fell below 100 for the first time this year during week 15 and we only received 16 reports from inland VT waterways as more volunteers and state and municipal seasonal staff left lakeside posts. Calm, dry, and relatively warm weather helped stimulate or sustain some significant blooms in Lake Champlain’s Main Lake North and Inland Sea and Malletts Bay had bloom activity as well. Read...
Aquatic plants in Lake Champlain will be dying back soon, but their blooms provide additional color to the vibrant autumn landscape. How did aquatic plants in the lake get there, and what helps make them successful away from land? We dig into the origin of plants, their journey from water to land and back again, and some specific adaptations of plants found in the Lake Champlain basin. Read...

Lake sturgeon are fish with a lot of superlatives. They have been on Earth longer than any flowering plant, can grow to the standing height of an adult man, and live to be supercentenarians in the right conditions a complicated relationship with people as it was Nearly driven to extinction and currently designated as endangered in Vermont and threatened in New York, lake sturgeon have complicated relationships with people. Read on to learn about their storied evolutionary history, “vintage” features, and how they got to the precarious state they’re in now. Read...
Aquatic invasive species (AIS) are among the major challenges facing Lake Champlain—they reduce biodiversity by outcompeting native species and disrupting ecological processes, and they can proliferate to impact water quality and recreation. LCC launched a volunteer community science initiative—the Champlain Aquatic invasive Monitoring Program (CHAMP)—to train folks how to identify and survey for key AIS in Lake Champlain. We still need volunteers to survey before the snow flies—you can sign up on our website and we’ll schedule additional trainings in your area. Read on to learn more about the program and stories from the field. Read...
Humans are the main conveyors of most aquatic invasive species, moving them from one body of water to another. Many of these troublesome plants and animals can be unintentionally transported on fishing gear, boating equipment, or even tiny amounts of water left in a watercraft. The simplest and most effective way to prevent the spread of aquatic invasives is to ensure that your vessel and all your equipment are cleaned, drained, and dried.
