At one time, a day of Chicago River water were pumped into the stockyards. So much stockyard waste drained into the South Fork of the river that it was called Bubbly Creek due to the gaseous products of decomposition. The creek bubbles to this day. When the city permanently reversed the flow of the Chicago River in 1900, the intent was to prevent the Stock Yards' waste products, along with other sewage, from flowing into Lake Michigan and contaminating the city's drinking water.
