A heavy rain storm on Halloween weekend that dropped 4 1/4 inches of rain over 2 days resulted in a peak flow of 22,400 cfps on the Middle Fork river. The rain was steady without a heavy downpour at any one time and there was no snow to melt in the mountains, factors which helped avoid major damage to the road. But flows of ~20,000 cfps were sustained for 5 hours. The Taylor river was especially wild — a log jam formed just above the turn off to Dingford Creek and caused part of the river to flow over the spur to the Taylor River trailhead. Later reports indicate that SUV style vehicles should still be able to negotiate the trench eroded across the road (see the last photo below).
