Winter Packraft Trips

I am wondering if anyone knows of any winter float trips here in Alaska. I have been thinking about Cooper landing - Jims landing since I think it’s open. Anybody
know? Let me know if this is foolish. Thanks

Hadn’t looked lately to see if its open, maybe the Knik from the old bridge to the new? I don’t have any winter pr experience so I am clueless to any additional concerns/hazards, but I am curious also.

Kenai River is usually open for paddling, although there’s only one way to find out for sure… hahahahaha…
