Lake Champlain

Vermonters love Lake Champlain.  We depend on the lake for fishing, swimming, boating, and other recreational pursuits.  It provides drinking water. Summer tourism and property values are tied to its health and beauty. The lake attracts businesses with a workforce that appreciates the lake’s natural beauty and Vermont’s working landscape.

The challenge is that too much pollution - runoff from rainwater or snowmelt that drains off of parking lots, roads and streets, logging roads, farm fields and croplands, and lawns is reaching Lake Champlain from the streams and rivers draining into it.  Phosphorus is one of the nutrient pollutants found in runoff and arguably the greatest threat to clean water in Lake Champlain. Too much phosphorus pollution stimulates excessive growth of algae. It can turn Lake Champlain water green, and even can be toxic to pets and people.

In June 2016, the U.S. Environmental Protection Agency (EPA) released new phosphorus pollution limits for Lake Champlain by establishing TMDLs (Total Maximum Daily Load) for twelve Vermont segments of Lake Champlain. The State of Vermont is seeking public input on the Draft Lake Champlain TMDLs Phase 1 Implementation Plan, which provides the framework for how these phosphorus pollution limits will be met.
