Chicago goes all-in on CHIRISH every March, and there’s no better way to celebrate than at the annual Chicago St. Patrick’s Day Parade in Grant Park! As one of the largest St. Patrick’s Day parades in the U.S., it draws over 100,000 spirited spectators eager to revel in the city’s Irish pride.
But the real showstopper? The dyeing of the Chicago River! The Chicago Journeymen Plumbers, Local 130 transform the river into a dazzling shade of emerald green—a tradition that’s as unique as it is breathtaking. You might wonder, “Isn’t the river always green?” Sure, on an average day, it has a murky tint, but on St. Patrick’s Day, it glows with a brilliant, vibrant green—a shade that mirrors the lush landscapes of Ireland, earning Chicago its rightful place as the Emerald City of the Midwest. And yes, every person on those boats? They’re all Chicago plumbers!
This beloved tradition began more than 60 years ago with an unexpected discovery. In 1961, Stephen Bailey, Business Manager of Chicago Plumbers Local 130, noticed a plumber’s white coveralls were mysteriously stained a perfect Irish green. When he inquired, he learned that the dye used to detect river leaks just happened to turn the ideal shade of emerald green. That’s when Bailey famously declared, “Call the mayor… we’re dyeing the Chicago River green!” And just like that, a legendary tradition was born.
So, grab your green gear, embrace the spirit of CHIRISH, and experience a St. Patrick’s Day like no other—only in Chicago! ☘️💚
