Grand River is not listed by name in the zone's species or waterbody exceptions or fish sanctuaries. Some exceptions cover whole townships or river systems, so read the zone page before you go.

Ice huts in Zone 19

Huts must be registered (free, once) and show the number outside; fabric shelters under 7 m² are exempt. Remove your hut by March 15, and in any case before the ice breaks up. You may fish with two lines through the ice in most waters, within 60 m and in sight of each.
