Sulphur Springs is located in Hillsborough County, between Florida & Nebraska Avenues, just South of the dog track along the Hillsborough River in Tampa.

DESCRIPTION:

The spring, which has a very strong flow, has been walled up to form a swimming pool with a spillway that leads to the river. It was a popular swimming hole until the rising nitrate/coliform levels forced health officials to close it to the public.

Although the property has been posted for years, a few diver's were granted permission to survey in 1994 and mapped over 4000 ft of passage. The cave opening has been widened a bit to allow easier access for divers with scooters. Connections to a couple of sinks to the North have also been established, but as far as I know, the entrances are impassable. For years the city of Tampa funneled stormwater runoff into numerous sinkholes in the area. Over time, the water quality in the spring has gradually deteriorated to the point that it is almost unsafe to dive. The pollutants from the runoff have caused the entire circumference of the cave to become lined with a thick coating of algal detritus which tends to be dislodged by the divers exhaust, thus reducing visibility.
Load up on your vitamin supplements before you dive this one.
