HILLSBOROUGH COUNTY, Fla. — The Hillsborough River will look green ahead of St. Patrick's Day.
At 10 a.m. Friday, crews started to test-dye the river.
It's all to prepare for the city's St. Patrick's Day Bash in downtown Tampa.
If you're wondering about the impact, green dye is safe for people and animals.
John Ring from the Water Production Division said the dye they use is medical food grade, typically used in tracing leaks within the water and for optical surgeries.
He adds it is 100% safe.
The River O' Green Festival was originally set for Saturday, March 18 but was moved to Friday, March 17 due to weather.
The free event at Curtis Hixon Parks includes live entertainment, food vendors and fun, family-friendly activities.
Ring said they're hoping for some blue skies to pop the green color!
