Lots of open water. From Leitch down to 507 is all fishable, though some holes have ice in the best fish holding areas... there's enough water to find a few fish in...
Between myself , GGP, and lonefisher we managed 4 'bows and a white. Tough, tough winter conditions. Slushy anchor ice on the bottom of most runs, floating slush to contend with on top, line and guides icing up all day, hell even my sjw was an iceberg most of the time. Tough, but my one fish made it worth the effort, just to say I did it!
