Quetico park maps dated 2007 and earlier incorrectly show the portage starting to the right of the creek. In fact the trailhead is 150 meters down shore to the left of the creek, and there is a small put-in in the middle. So the actual portage is (2) 200m portages. Topographic maps (dated 1995) have it shown correctly.
Lake after portage: Walter Lake
Known campsites: not sure
