I'm planning a hunt up the haul road for about a week the 3rd or 4th week of Sept. I'll be bow hunting. I'm planning on taking my Zodiak for floating/crossing the Sag. I've never gone this late in the year and could use some reliable advice on weather and river conditions for that time of year. I've read through a lot of posts and I'm expecting snow but what about ice. Thanks in advance for any assistance.
