Snake River catfish

Maybe I have the wrong mental picture of "riffles." In that section I didn't see any currents I thought of as riffles. If it was shallow, it was covered in mats of weeds.

According to Wikapedia: "A Riffle is a short, relatively shallow and coarse-bedded length of stream over which the stream flows at higher velocity and higher turbulence than it normally does in comparison to a pool."

The Marsing to Walter's Ferry stretch is a series of very large pools connected by riffles. Some of the riffles have weeds in patches, some don't. Few of the RIFFLES have weeds in mats, except along the edges.
