Muddy brown water fills Sandusky Bay, just south of Lake Erie in this astronaut photograph. The small city of Sandusky occupies the southeastern shore of the bay. Highway 2 can be seen arcing around the south side of the city. Ferries connect Sandusky to Pelee Island (not visible) in the middle of the lake. In earlier days, Sandusky Bay was known as one of the port sites best protected from rough waters in the Great Lakes.
The most striking aspect of this image is the flow of the brown water in and out of the mouth of the bay. Slight movement of lake surface water, driven mainly by wind, causes a small ebb and flow of bay water. Sediment-charged water is derived from agricultural fields along the Sandusky River upstream. Mud plumes in Lake Erie originate from prior pulses of muddy water from the bay. When this image was taken, some clear, lake water (blue-green strip) appeared to be flowing into the bay.
Sandusky lies midway between Toledo and Cleveland, both about an hour's drive away. Sandusky has a diverse economic base in engineering and chemical plants, as well as boasting one of the most popular vacation destinations in the United States, drawing millions of visitors each year to its very large amusement park, located on the eastern spit between Sandusky Bay and Lake Erie. NASA Glenn Research Center - Plum Brook Station also appears in this image, in the lower right corner.
