The EQT Three Rivers Regatta is 3 days of activities and entertainment primarily in and around Pittsburgh's three rivers and Point State Park ranging from live bands to boat races.  The event itself is free to the public.  

 

A percentage of the funds raised through event sponsorship is allotted to the Regatta Board which distributes grants to other nonprofit causes that promote clean waterways and recreational river use.
