As for Fisher and McKenzie inaccuracies- says right on the maps "Not intended for navigation".

Fisher and McKenzie maps are not inaccurate due to age, they are just inaccurate.

I bought the 2014 version at the ranger station in Atikokan in Sept 2014. The ranger told me the only difference at that time was a new long portage added on the Maligne to bypass swifts in high water conditions. You would probably skip it in normal conditions.


Yup.  Was told the same when we picked up our permit late-June.  As we went from Sturgeon to Poohbah, we completed three portages on the upper Maligne and couldn't recall seeing where the "new" one was added....I think it was created for upstream paddlers....

We also went across LLC down the Namakan and Up the Quetico River back to Beaverhouse.  The newer Chrismar listed longer portage lengths on 2 or 3 of the 4 portages going up the Quetico River.  I think the older lengths (around 250-350 yards) were more accurate....a couple of the newer lengths had them around 700+ which is way longer than they actually were....

But the Chrismar is still way more accurate overall when compared to Fisher or MacKenzie maps....

I found the same thing but in reverse on my 21 day solo trip route. Before I went, I looked the portages over and compared the new Chrismar with my old McKenzie's and when they disagreed, I went to the new Q-planner site.

That only made things worse because it varied between the two.
When they were ALL off, it was by a lot, more than you'd think it would be even allowing for minor human error.

One of my goals next trip to to bring a pedometer and mark each portage length down and then put any differences in my trip report.

On one hand, for me the length doesn't matter because if that what it takes to go where I want, I'm doing it regardless. But some people/groups have time/physical issues and a portage that is way longer than marked could be an issue for them?
