Clean Water

The diverse ecosystems, working
landscapes, and vibrant communities
that inspire and sustain us depend on
clean water. Learn about pollution
reduction strategies.

Healthy Habitats
Connect Us All

Lakeshores, stream banks, and wetlands are critical to clean
water and biodiversity. Learn about efforts to improve
habitat connectivity in the Basin ecosystem.

We Care for
What We Know

Recreation fosters stewardship of the Basin’s rich
natural and cultural heritage by connecting people
to the landscape while supporting local economies.
Learn about ways to explore the Basin.

Informed Citizens
Make Wiser Choices

Citizens who have an understanding and
appreciation of water resources make informed
choices about actions that might contribute to
pollution. Learn about education programs.


    Clean Water commitment:
    Working to Achieve TMDL Goals

    Lake Champlain is generally a source of reliable clean water, but too much phosphorus in the Lake poses pollution challenges. The Total Maximum Daily Load (TMDL) is a pollution budget that establishes limits for the amount of phosphorus the lake can receive and still remain healthy. It also identifies the reductions needed from different areas of the landscape for healthy water in the lake.

    Explore the animations and videos here to learn why phosphorus is a problem, what the TMDL is, and how people working on the landscape in a variety of ways are helping to achieve the goals of the Lake Champlain phosphorus Total Maximum Daily Load (TMDL).
