Observing Lake Ice-Off for the State

Posted at: 03/31/2014 3:14 PM

The Minnesota Pollution Control Agency is asking citizens to document lake ice-off dates, or the date when ice is essentially gone from a lake. Lake ice-off is an indicator of changing climate trends.

The MPCA collects both lake ice-on and ice-off data and makes it available for use by researchers and the State Climatology Office. Citizen observers make it possible to maintain records of ice data across the state on vast numbers of lakes.

To submit information about ice-out dates on a lake near you, send an email to ice.pca@state.mn.us
