That road is drifted in from what I hear. Passable to snowmobiles/atvs. I've been using the one that comes off the rock creek/skalkaho road and goes through the lower campground up onto the dam. It's plowed up to the lower campground. Snows not to bad from there on. Last friday I drove my truck across the dam to the bridge that crosses the spillway. Didn't go any farther than that. Today I drove all the way to where I fished. As long as you have 4-wheel drive and some good tires, you'll be fine. - SpitzoMT
