Chicago River Green For St. Patrick's Day 2021

Each year, the city of Chicago celebrates St. Patrick's Day with a unique tradition. It dyes a portion of the Chicago bright florescent green. How did this all get started and how is it done? Here are three fun facts about the Windy City's aquatic feat:

  • The river is dyed on the Saturday before St. Patrick's Day between Wabash Avenue and Columbus Drive, right in the heart of downtown Chicago.
  • Boat crews manned by volunteers from two families are responsible for dispersing the dye every year. Each person on the boat is related by blood or marriage to Mike Butler or Tom Rowan, who were the two men responsible for the first river dyeing in 1962.
  • The orange powder which is used to dye the river is a 'secret recipe'. Roughly 40 lbs of the substance is dropped into the river each year. It typically takes about 45 minutes for the river to reach its electric green coloring, and this effect can stay for few days.
