Since you are in Emerald Park there might be some decent fat biking terrain at White Butte if there is enough foot traffic on the path between the south and north parking lots. There are a few trails dedicated to snowshoeing and fat biking, I think they are marked as the ski club doesn't want people walking/biking/snowshoeing on the ski trails. I haven't heard from anyone that has gone riding there so no idea what the conditions are like. Since I'm in the NW I go to Wascana Trails instead.
Here is the map with the biking trails added:
