Branford Springs
Located in the town of Branford on the Suwannee river, Branford spring is a popular spot for the locals.  Large pool with depths to about 9 feet.  There is a small vent on the south side of the spring that leads to a cave blocked by concrete rubble.  A wooden deck has been built around the spring.  Water clarity depends on how many people are swimming in it.  Depths vary w/ the river height.  Decent snorkel dive.  There is a dive shop close by for air fills.
