Join Aquatic Ecologist Kellie Merrell and Program Manager Oliver Pierson of DEC’s Lakes and Ponds Program to learn about the status of Vermont’s lakes. They will cover phosphorus trends in lakes and how we can proactively protect lake water quality.

Vermont is home to some of the clearest lakes in the nation due to low levels of nutrients like phosphorus. However, recent monitoring shows some of Vermont’s lowest nutrient lakes have significantly increasing phosphorus concentrations. Reversing this decreasing water quality trend will be expensive and difficult if left unaddressed. The Vermont Water Quality Standards provide an opportunity to reclassify lakes that meet certain criteria to a more protective category. This reclassification triggers additional land use restrictions and provides a mechanism for quicker restorative actions. Is it time to reclassify lakes in our state?
