Backwater from the St. Johns River, at least in part associated with tidal effects, frequently makes it impracticable to measure the spring discharge. Several small springs issue from the sandy bottom near the south edge edge of the run midway between the main spring pool and the river. One of these reportedly has a considerably lower chloride concentration than does Welaka Spring and has at times been used as a domestic water supply. Undeveloped, but used for swimming. Analyses by U.S. Geological Survey.
Units are in milligrams per liter unless otherwise indicated.
