The dolphins, which included two calves, had been trapped in the canal since Sunday.
Wildlife officials told WFTS because the dolphins did not appear to be in distress, they waited a day to see if they would exit on their own with the tides.
On Monday, wildlife officers mapped out the canal and the waterways nearby to come up with a plan of action to push them to freedom.
They then formed a human chain and used sounds and vibrations of the water to lead the dolphins back into Riviera Bay
