Ice Out Day In Vermont

VERMONT - As temperatures begin to heat up, our lakes and ponds in Vermont are starting to lose their layers of ice. The day a lake or pond has no ice from shore to shore is known as the 'ice out' date.  And The Vermont Department of Environmental Conservation (DEC) is asking for your help to notify them when the 'ice out' day occurs.


Once the lakes and ponds lose their ice, the team at the DEC goes in and begins their spring water quality sampling efforts. Oliver Pierson, Vermont's Lakes and Ponds Management and Protection program manager says, "the more data we have from around the state on the timing of 'ice out', the better we can track water quality changes and impacts from climate change on our lakes." The data collection goes back to 1977, and helps the scientists at the DEC see the total amount of phosphorus a lake has available during the growing season for phytoplankton, algae, and aquatic plants.

"Tracking 'ice out' dates over time can also be important because in some lakes, earlier 'ice out' may lead to more phosphorus release from sediments during the summer, which can help fuel algae blooms and growth of aquatic nuisance vegetation," said Leslie Matthews, Environmental Scientist with the DEC.

The DEC needs your help to notify them when 'ice out' day arrives. They created an online form where you can notify them at the Agency of Natural Recourses website.
