Ice On / Ice Off Data
The information on ice on and ice off dates can be useful as an indicator of the current climatic conditions, and over time it can be used to help monitor indications of climate change. We hope at some point in the future to be able to provide capability for upload and visualization of data. For now, if you start keeping track of the ice on and ice off data, you can start to build a set of data that can be used for trend analysis.
Some lakes have existing definitiions of ice-on and ice-off dates. If there's a tradtion, certainly use that and gather any historical records you can find. If you don't have a tradition, one that is widely used is to declare ice on when the ice prevents someone from boating to the deepest part of the lake from all the points on shore. Ice off is when you can boat to the deepest part of the lake from some shorepoint.
Ice on / ice off data can be entered as part of the electronic data collection - see CSLAP online. Or you can note this information on your first CSLAP sampling form of the year, or email it to Nancy Mueller.
