How trout successfully
climb the falls - Photo #6
Notice the distinctive line at the top
of the fall where the white and blue water meet. If the trout can get into the blue water
area, they have made it. The reason for the color change is this is the edge of the fall
where air mixes with water creating the white color. The trout can't get a strong lock in
the air/water mix, which means they can't swim at full strength. This big brown will make
it. While she landed just a little short of the line, she landed at the right angle which
means she can successfully swim the last foot.
