The Ministry of Environment reminds you that ice fishing season closes in northern Saskatchewan on April 15th so all fishing shelters in areas north of highway 16 must be removed by March 31st. They note each spring a number of ice fishing shelters are abandoned and this creates identification and cleanup challenges for the province and can pose environmental concerns. All litter including fish entrails and offal must also be removed when the ice shelters are taken off the ice.
If shelters are not removed owners can be prosecuted and the structure and contents may be confiscated and removed by the ministry. As an example they report in 2014 a Saskatoon man was fined 28 hundred dollars for leaving an unmarked ice fishing shelter on the ice covered waters of Blackstrap Lake and for littering.
