Check out this video from May 6, 2017 showing the South Fork Boise River with water flows running about 7,000 cfs.
The first mile or so of the river is shown in the video, including the drop at the boat ramp that was formed from the debris flows of September 12, 2013.
As of May 10 the flows are now 8,500 cfs. This should be moving some sediment.
