I was up there a few weeks back. Not all that familiar with the lake though. We fished out of Dwight in Dwight Bay and Whitehouse Bay further south. You can also fish Portage Bay out of South Portage. Some guys we ran into were fishing out of Dorset, but not sure from where.
The only huts I've seen for rent were in Dwight Bay, but there might be others.
You can contact
Bondi Village Resort or
Logging Chain Lodge to ask about their huts.
Good luck!
