Cyanobacteria
Cyanobacteria blooms are a significant issue in Lake Champlain and can pose health risks to people and pets. Blooms can vary widely in appearance, making awareness and monitoring especially important. Learn how to recognize blooms and consider joining our cyanobacteria monitoring program.
Aquatic Invasive Species
Invasive species pose a major threat to the lake's ecological health and recreational access. Through LCC's Champlain Aquatic invasive Monitoring Program (CHAMP), we train and support volunteers to survey and report on invasive species in the lake.
Volunteer
Volunteers are the heart and soul of the Lake Champlain Committee. Our community science monitoring programs, the Lake Champlain Paddlers' Trail, and education and outreach work would not be possible without the help of dedicated folks that share a love for Lake Champlain and a passion to protect it.
LCC is a bi-state nonprofit that uses science-based advocacy, education, and collaborative action to protect and restore water quality, safeguard natural habitats, foster stewardship, and ensure recreational access.
