At least 4-5 individuals seen, at least 300m upstream from the ocean.
not a personal observation.
Six individual sea turtles present from Pacific Coast Highway north to the DWP power plant; none found further upstream past the first power plant. Count is conservative; there may have been more. At the marked location (where photo was taken), three individuals visible at once, working the flow line of the warm water outflow. A plant worker thought that one would see more turtles in winter when overall surrounding water was cooler.
The green sea turtle (Chelonia mydas), also known as the green turtle, black (sea) turtle, or Pacific green turtle, is a large sea turtle of the family Cheloniidae. It is the only species in the genus Chelonia. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans. The common name comes from the usually green fat found beneath its carapace.
