10 years or more, a friend, Blair left a shack on the ice, Fort Quappelle lakes, lives in Regina, knock at the door 6:30 PM DNR Officer gave him tickets and citation, expense charges, storage charges, and had to go out to Fort Quappelle and pick up what was left of shack by certain date, it was trash because of care taken in removal process. Cost him close to 700.00 ten years ago. Hopefully charges have gone up with the environmental concerns of today and tomorrow.
