Wilson River, Cobrabald NSW: After heavy rainfall, a fresh in the river brings froth and leaves. I used a slow exposure of three seconds to allow the moving objects to draw their paths on the surface of the water. The result reminds me of a fish migration.

In this river the fish could be Australian Bass (Macquaria novemaculeata) returning to the freshwater for the summer, after spawning in brackish water near Telegraph Point in the winter.
