A 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.

The animations and videos here explain 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).
