While St. Patrick's Day isn't until Monday, Chicago's iconic tradition dyeing the river green is happening Saturday. Here is how to watch the event.

Jamestown dyes part of the Chadakoin River green each year to celebrate St. Patrick’s Day. The Pearl City of Western New York is one of only three cities in the United States to color their rivers green for the holiday, according to I LOVE NY. (The other two are the Windy City and Tampa.)
