TomT -
I don't disagree w/OS re: Sturgeon as a fishery, having just come off a very nice fishing week right there. It's a big lake and diverse fishery that offers a lot. We did well both with walleyes & bass there.
On the other hand, I DO LIKE the lakes you've selected and probably for the reasons you have chosen them. My experience has been: Camel produces very nice walleyes and McDougall is an exceptional lake for smallmouth. That whole string of Cutty Creek lakes offers great walleye fishing. With regard to McDougall, I would refer you to a BWJ article written by Tim Mead (our very own "Ancient Angler") back in the early 2000's, I think. Titled something like "Back to McDougall", it was all about the great smallmouth fishing there. And, if it's BIG smallmouth you're after, well, I watched my brother take the largest smallmouth I've ever seen just across the portage over on Russell Lake.
I recommend a bit of care with campsite selection on those two lakes. Most maps will show 3 sites on Camel but only ZC is really any good. I found the one in the far western bay of that lake to be absolutely infested with no-see-ums twelve years ago. Since then I've stayed at ZC. On McDougall, it's tempting to grab one of those "peninsula point sites" and - if the weather is good - you can really enjoy the great views they offer. On the other hand, if the weather is bad, you are VERY exposed. I ran into that situation last September on a similarly-exposed site. Those September storms can be bad news! If the weather looks shaky, there is a decent campsite tucked in on the west side of that smaller eastern bay that should service you quite nicely. It doesn't show on many maps.
September will be a great time of year to visit that area of the park. I'm envious!
