It’s a sign that our brutal winter may finally be coming to an end – the spring thaw is here, and ice is starting to disappear from local lakes.

To help track climate trends and keep accurate records, the Minnesota Pollution Control Agency is asking community members to document when the ice disappears from lakes, or the ice-off data.

The agency collects this data to be studied by researchers and the Department of Natural Resources’ State Climatology Office. Researchers say it helps them look at how climate trends affect lake health, wildlife, and recreational lake use.

Community members can help collect this data by reporting when the water is ice-free. To submit information about ice-out dates on a lake near you, send an email to
