Minnesota Pollution Control Agency asks for help with ice data

The Minnesota Pollution Control Agency is asking residents to tell it when ice disappears from lakes around the state.

“Lake ice-off” is an important milestone for the state and it could suggest changing climate trends, the agency said. The data is used by the State Climatology Office at the Department of Natural Resources.

Ice-off is defined as the date when “ice is essentially gone from the lake,” the MPCA said. “If there is some ice pushed up on shore, but the water is ice-free, the ice is considered to be out.”
