Monitoring Ice-on/Ice-off
Ice on/Ice off monitoring is a simple type of lake monitoring. Volunteers simply record the date that ice completely covers the lake in the fall, and record the date that the ice is completely gone from the lake in the spring. This information is used to track changes in the open-water season, which is useful in many different types of lake-related research projects.
