minor riffles?

From the put-in, there is very little which can be seen (via online aerial/satellite photos as of 2017, anyway) to indicate any rapids, riffles or rips until this point. (Which is not to say there isn't or couldn't be, just that it is not evident.)

A minor rocky shoals appears at this point, just after one of many broad meanders, and after a small island. These appear to last about 2/10ths of a mile, and perhaps a bit beyond.
