Report from the party at the cabin the weekend of January 14-15.
Got back on Friday, January 27th from Watersprite Lake. Our vehicle was a Toyota Cruiser. 4WD was engaged from the highway due to the icy roadway. Mamquam FSR was plowed to the turnoff to Skookum power plant and a short distance up Skookum Branch to the power plant gate. There is a large plowed parking area at the gate and is marked KM 13.5. We skied into the hut on Thursday in just over 4 hours with overnight packs. I would not advise traveling further than the plowed road. Although the snow pack is about one half meter in depth on the road you can easily punch through and get stuck. There is a Facebook post this week describing a rescue of a stuck Toyota RAV4 at KM 16: https://www.facebook.com/photo.php?fbid=10155045447144673&set=gm.1379679642083716&type=3&theater
Report from February 23rd. We drove to KM 13.5 which is the end of the plowed road at Skookum powerhouse. Continuous hard packed snow from there. Sections between KM 13.5 and KM 15 will likely melt out to bare ground if there's sun over the next week or two. Between KM 16 and the dam near KM 20 there is a good meter of snow. The Mamquam FSR is still icy in spots but we did not need chains.
Report from the party at the cabin the weekend of April 2.
The group reported you can drive to KM 16 which is 2.5 km beyond the power plant at Skookum Creek and elevation of 840 meters.

The Mamquam forest service road is as usual full of pot holes.
