Lightning Creek at Clark Fork, Idaho: December 9, 2015
On December 9, 2015, heavy rain and resulting snowmelt swelled many Pacific Northwest rivers to flood stage. One of these streams was Lightning Creek at Clark Fork, Idaho. In a 24-hour period, Lightning Creek rose from about 200 cubic feet per second (cfs) to more than 10,000 cfs as recorded at USGS strreamgage 12392155.
