The cool water of the spring discharges into a metal casement, about four feet in diameter and five feet tall, that has been placed over the spring. The pipe, which is attached to a dock, acts as a reservoir for a small watering system. The water surface in Lake Harris was low at the time of the visit, and the pipe was just at the waterline. Nonetheless, the water level in the pipe was about three feet above the water level in the lake.
This spring was located using by aerial thermography and is documented in St. Johns River Water Management District's Special Publication SJ2008-SP7, Submerged Springs Site Documentation: August and September 2007. It was visited on September 12, 2007 by Tom Morris and Mark Long, of Karst Environmental Services, Inc. accompanied by Jeff Davis of the SJRWMD. A video of the spring is available from the SJRWMD.
