While I haven't been there yet this year, I have been gathering all the info I could on trail conditions. This is a pretty good picture of what it'll be like:
And for actual snow data:
About the closest actual sensor I could find is Charlotte Lake, and they have close to 4' of snow at the moment (at 10,200). The satellite date is more vague, pretty much showing anything from 5-9 feet for the majority of the area. I have no idea the accuracy of any of it.
From the SEKI website it looks like water levels will be gnarly, the trail will be non-existent for stretches, and plenty of snow.
