Everywhere I looked in the water today there were many thousands of these little critters.
As long as there was a bit of current.
They seemed to prefer the lower third of the water column.
In places there was also several Waterboatmen in attendance.
Whether feeding or just in the area I don't know.
Size varied from less than a mm to 3 or so mm.
