While on a work break by the river, I saw an enormous carp swim by. Now, impressive as the size of this fish was, carp tend to be quite huge, so that was not so remarkable in and of itself. What did strike me was the color. Your average Yahara River carp is a muddy river brown. This was a streak of orange that totally popped against the greenish color of the water. The only places I've seen fish that color have been ornamental ponds. Seems we have an escaped koi on the loose. 'Twas pretty.
