I was out on Spencer about a month ago and fishing was good but they have had a bunch more snow fall up there since then.
Was on Seibert this past weekend and it's either Quad or Skidoo's only unless you have a some type of modified 4x4. Fishing was ok at best on Seibert. Some surface water in places. Lots of surface water along the western side of the lake where it is protected from the wind. Could be even worse on Spencer as it does see as much wind as Seibert. Road in is fine.
Remeber accessing Spencer from Seibert is unlawful.
