I can't give current conditions for any of it, but may have some helpful information if you are going west through Rush and Banadad, then returning from Long Island via Muskeg, Kiskadinna, Omega, and Henson.
In 2012 I entered at Cross Bay and went east from Long Island through Muskeg, Kiskadinna, Omega, Henson, Allen, and Horseshoe to exit at Lizz to Poplar.
Trip Report Pictures see 2012 album.
You'll be happy to know I did see a moose, even got a picture, on Muskeg Creek just after the portage from Long Island. I stayed at the campsite next to that portage on Long Island.
That portage was a boulder field and the Muskeg Creek end was flooded out. Be quiet as you approach the Muskeg Creek end keep your eyes open.
The Muskeg-Kiskadinna portage is moderately long and has a very steep climb (known as "The Wall"). The next one to Omega is short but has an awkward narrow climb to begin.
Pack light and be careful on those portages. It was a very nice area, although a couple of tough portages. I think you have a long tough day to get to Long Island, too. I think Kendra did that trip not real long ago and posted a trip report, so you might check for that under the Planning tab under EP #49 trip reports for information on the first part.
I hope you have a good trip.
