The largest inland lake in Michigan and the center of the state's ice fishing culture. Shallow, wind exposed for an inland lake, and surrounded by more shanties in February than anywhere else in Michigan.
Access areas: Houghton Lake town accesses, Prudenville, North Shore. Temperature record from Houghton Lake, Roscommon County.

Houghton Lake averages only around twenty feet deep, which is why it freezes early relative to the deep northern lakes and why the ice fishing tradition here is so entrenched. There is no satellite ice product for inland lakes at this scale, so the only signal this page can honestly offer is accumulated cold from the Houghton Lake climate station, which sits essentially on the water. That is a real signal for whether ice should be forming, and it is not a measurement of the ice.
There is no NOAA satellite ice cover product for inland lakes at this scale. For this water the only honest signal available from a distance is accumulated cold, and that is all this page claims to show.
The NOAA ice cover product covers the Great Lakes, not inland lakes. For Houghton Lake this page shows accumulated cold only, and says so rather than implying more.
At roughly twenty feet average depth this lake gives up heat fast and typically locks up ahead of the deeper northern lakes.
Heavy shanty and vehicle traffic concentrates load and cuts holes across the sheet. Popular does not mean safe.
These six waters behave differently enough that a plan built for one can be wrong on another. Depth, current, and wind exposure all change the picture.
