Drove to within about 2 miles of the whitewater trailhead in early april before I was stopped by snow.  Walked the rest of the way to the trailhead.  At that time there was at least a couple of feet on the road when you topped outbefore the trailhead.  I don't think there were any windfalls other than one that's already been cut at the beginning of the road.  Hard to say about the snow now though.
