We found between three and four there was some good walleye fishing in the channel. We drifted back and forth in front of our campsite and each caught a bunch. Had enough for two meals that day! Try to get a site on the east end of lake three. They are fairly spread apart and large. But watch out for strong NW winds!
Very easy to get to with only 2 portages. It is a nice place. I agree do yourself a favor and go onto Insula. Insula is well worth the extra portages.
