Pemberton Lake is located in the hills to the north of Pinantan Lake. It is a small lake with a primitive Rec Site and a rough 1 km road, accessed from the Hyas Lake Forest Service Road.
I put my folding kayak into a pack and hiked in to the lake.
The launch area is muddy, although there are some firmer spots to the east. I paddled around the lake, repacked the kayak, then hiked back out.
There were fish in the lake and there was an osprey in residence and loons on the lake. There was no one else on the track, nor on the lake.
A few moments of the pack and paddle are found in this YouTube video:
