Recent winters in New Hampshire have been warming and bringing erratic temperature and precipitation swings. This has been impacting lake ice cover, to the point where lakes with traditionally consistent and thick ice cover are showing later ice-in and earlier ice-out dates. This is threatening wintertime ice recreation, in some cases even impacting long-standing ice fishing events. Additionally, changes to ice cover and ice thickness through the winter season can have large, and uncertain impacts on the overall physical and biological health of the lakes.

The goal of this project is to develop a citizen-driven method of recording lake ice and snow cover thickness throughout the winter. We are interested in how lake snow and ice cover is changing and how it might potentially impact the physical and biological characteristics of our lakes.​ 

However, we need your help​​!

Monitoring of Lake Ice and Snow through citizen science!

Tracking lake ice and snow thickness during winter is challenging! In New Hampshire, we are fortunate that many enjoy spending time on lakes during the winter ice fishing, skating, skiing, walking, etc. In this project, we hope to capitalize on you hearty Granite Staters to help us track lake ice and snow through the winter. There are several ways to contribute, and participation is easy! See below for ways you can contribute.
