Uncaught catfish can swim through and turn to river pebbles 

Wind and currents drive on their own accord
or so we would be told; there are currents
a top of currents dust to water to air to star dust
the moon the earth the planets ‘round
an apathetic sun and back down a clockwork
a whirly hurly a tornado a hurricane the white caps
on the river when the wind currents are colder
than the water and the old rivermen laugh at the office dwellers who insist on living in the forgetting that currents still sweep us along, river pebbles
dashed against waves
from one place to another
