Summary

Indian Washtub Spring is a submerged spring feature located in Merritt’s Mill Pond near Marianna, Florida. Despite its name, the site is technically not a traditional spring vent but a ponor, a natural opening where water flows downward into cracks in the limestone rather than flowing out of the aquifer.

The feature lies along the western shoreline of Merritt’s Mill Pond, approximately 200 yards downstream from Shangri-La Spring. The site sits beneath a limestone ledge in about 20 feet of water, where a large crevice in the rock marks the location of the ponor.

Like other springs in the Merritt’s Mill Pond system, Indian Washtub is connected to the broader Jackson Blue spring and cave network that feeds the pond with clear groundwater from the Floridan Aquifer.

Because the site is underwater and located within the pond, it is accessible only by boat, kayak, or paddleboard.

Activities and Access

Indian Washtub Spring is located in open water within Merritt’s Mill Pond and cannot be reached directly from land. Most people get there by launching from Jackson Blue Springs Recreation Area or from the public boat ramp on Hunter Fish Camp Road.

From the public boat ramp, paddlers can travel approximately two miles upstream through the clear waters of Merritt’s Mill Pond. The spring lies on the west (left) side of the pond when traveling upstream.

The site is located near an old dock structure extending from a set of concrete steps on the shoreline. The vent itself sits about 35 feet before the dock and can be identified underwater by a long crevice in the limestone bottom.

There are no facilities directly at the spring, though nearby Jackson Blue Springs Recreation Area offers amenities such as parking, picnic areas, and swimming areas.

Spring Characteristics

Indian Washtub Spring differs from many Florida springs because it functions primarily as a ponor, where water flows downward into the aquifer rather than emerging from it.

The main feature is a large limestone fissure located roughly 20 feet below the surface beneath a rocky ledge along the shoreline. A fallen log lies across part of the crevice, and several collapsed limestone boulders appear to partially block the opening.

These collapsed rocks likely reduced the water flow at the site and may have prevented the development of a larger cave system. Because of sediment and low water movement, the area can sometimes appear slightly hazy compared with the clearer vents elsewhere in Merritt’s Mill Pond.

Diving and Snorkeling

Indian Washtub Spring is not an ideal place for diving and snorkeling. Collapsed rock and silt around the fissure murky the water, and shade from the surrounding vegetation can make conditions worse.
