I am a Scuba Instructor. I get a teaching permit each year to teach scuba at Blue Springs State Park ($150 annually) I was just informed by the Ranger Station that the park is closed to ALL water activity until March 2007 due to the number of manatees taking refuge in the spring from the cold ocean water. So, if you are planning on diving Blue Springs, make your plans for AFTER March. I will be getting a full refund from the state for my permit.
