Located just east of Marianna, Merritt?s Mill Pond is actually a 202-acre reservoir fed mostly by one spring named Blue Spring or Jackson Blue. Considered to be one of the most beautiful springs to explore by divers, Jackson Blue?s main vent is a limestone cave close to 5,000 ft. in length. It is a first magnitude spring, discharging an average of about 76 million gallons a day, and is the head waters of Merritt's Mill Pond.
