If shelters aren’t removed by the deadline, owners may be prosecuted, and houses may be confiscated or destroyed by a conservation officer. If weather conditions make removal of houses difficult by the deadline, the DNR says residents should contact their local conservations officer.

“And don’t just remove your fish house — make sure you clean up everything around it and leave only an impression in the ice or snow,” said DNR conservation officer Leah Kampa, in the release. “It’s been heartening this winter to see people’s willingness to clean up the litter other people leave, but it’s unfortunate some people don’t take the time to clean up after themselves.”

Any violators caught littering will be cited as a result.

The DNR says that fish houses may still be on the ice after the deadline, but they must be occupied if they’re out between midnight and one hour before sunrise.
