From the Wisconsin DNR Facebook page:
Heads up, anglers: Two ice shanty removal deadlines are coming this week.
This week's deadlines to remove permanent ice shanties, or those that are not removed daily, on inland and boundary waters are:
– Wisconsin – Minnesota boundary waters by March 1 – Inland waters south of Highway 64 by March 5
Portable ice shanties can still be used after these dates, so long as they are removed from the ice when they are not actively in use and at the end of each day.
Owners having difficulty removing their shanty should seek help from local fishing clubs, vendors and other anglers.
The removal deadlines are to ensure shanties are removed and to avoid the additional costs and hazards of shanties breaking through the ice.
When you're out there removing your shanty, remember that no ice is safe ice. The DNR does not monitor ice conditions, so anglers should check with local fishing clubs and bait shops for current ice conditions.
Here are a few ice safety tips to remember:
Carry a cell phone, and let people know where you are going and when you’ll return home.
Wear proper clothing and equipment, including a life jacket or a float coat, to help you stay afloat and to help maintain body heat.
Wear ice creepers attached to boots to prevent slipping on clear ice.
Carry a spud bar to check the ice while walking to new areas.
Carry a few spikes and a length of light rope in an easily accessible pocket to help pull yourself – or others – out of the ice.
If you fall in, remain as calm as possible. While attempting to get out of the water, call for help. Anyone who attempts to rescue you should use a rope or something similar to avoid falling through themselves.
Do not travel in unfamiliar areas or at night.
