Description

The river splits around an Island while dropping steadily.   At low flows the left channel tends to be a bit deeper, but it has several obstacle rocks in awkward locations.   The right channel tends to be wider and cleaner, but more shallow.  

Where the channels come back together the flow pushes against granite outcroppings on the river right.
