Everything You Need to Know about Dying the Chicago River Green

But Chicagoans are known for their crazy manifestations of Irish pride. Locals watch every year as the Chicago River becomes the ideal shade of shamrock green. However, how did this custom start? Let’s talk about the origins of the custom of colouring the Chicago River green and look at several techniques for accomplishing so.

Origins of Dying the Chicago River Green

The custom of dyeing the Chicago River green dates back more than fifty years, even if locals may not be aware to it. Surprisingly, this wasn’t originally intended to be a fun way for the community to celebrate St. Patrick’s Day. The Chicago mayor embarked on a mission in 1961 to identify the source of the sewage flowing into the Chicago River. The Chicago Journeymen Plumbers Local Union employed tiny amounts of green dye to find leaks in the pipes in order to ascertain this. Many believed that the hue was akin to the green shamrock that is connected to St. Patrick’s Day. For this reason, in 1962, the union chose to mark the holiday by dumping a significant amount of this dye into the Chicago River! Since then, a lot of locals and visitors alike have grown to adore this annual ritual.

How It’s Achieved

Despite the fact that it appears like a massive endeavour, completing it is not too difficult. Two boats and a small group of labourers are all that are needed to spread the dye throughout the river. The dye itself is supplied in powder form, which needs to be applied by hand. From beginning to end, the complete operation only takes roughly two hours.
