"Fishing piers and floating gardens welcome anglers to the Chicago Riverwalk, but a few blocks upstream is a little-known threat to fish and other aquatic life in the city’s steadily improving waterway: Trump International Hotel & Tower.

State records obtained by the Tribune show the president’s glass-and-steel skyscraper is one of the largest users of Chicago River water for its cooling systems, siphoning nearly 20 million gallons a day through intakes so powerful the machines could fill an Olympic swimming pool in less than an hour, then pumping the water back into the river up to 35 degrees hotter.

Like other large users that draw water directly from rivers or lakes, Trump Tower is required to follow federal and state regulations detailing how facilities should limit the number of fish pinned against intake screens or killed by sudden changes in pressure and temperature."
