Tampa, Florida -- St. Patrick's Day is almost here and Tampa is getting ready for the Mayor's 3rd annual "River O' Green."
A small portion of the Hillsborough River was dyed as a test Thursday morning. It will take about 200 gallons of dye to get that true Kelly Green color.
Mayor Bob Buckhorn will lead the event Saturday morning from 11-4 when crews dye the Hillsborough River between the Cass Street Bridge and Kennedy Bridge.
City engineers explained that the dye is safe, non-toxic and bio-degradable.
"It's not something we do every day in the water department so we're very excited to have the opportunity to show what we can do," said engineer Eric Weiss, City of Tampa.
The event is sponsored by Grow Financial.
