The folloiwng ice report is by Tongue River Reservoir State Park:

Ice Update 12-26-25:
Hope you had a nice Christmas. Most of the lake has ice covering over it now. It is thawing and refreezing daily and only 1-2″ thick. It may slowly thicken as the weeks go by. The south end may still have 3-4 inches. Use caution if you come fish. Remember, safe ice is 4″ plus.
Happy New year!
