You can pull over the beaver dam, but if you care about your canoe, do the 5 rod portage. They don't get easier than this.
Lake after portage: Slate
Known campsites: 1
The lake starts out as a small stream. The rest of the lake looks like it might hold some fish, but we just passed through. There is a campsite right on the portage into Saganagons. The site is small and would probably interfere with any people wanting to portage. There is a much better site on the point across from the portage on little Sag.
