Portions of the following information were taken from Florida Geological Survey Bulletin 66.
The spring is located in the town of Weeki Wachee on the west side of US 19. From the intersection of US 19 and SR 50, drive south 0.2 miles. Turn west (right) into Weeki Wachee Springs Park parking lot. The spring vent is in the large pool used for mermaid shows.
Description - Weeki Wachee Spring discharges from the bottom of a conical depression with gentle side slopes. The spring pool measures 165 ft east to west and 210 ft north to south. Spring depth is 45 ft over the vent in the center of the pool. Bare limestone is located near the vent, but none is exposed around the pool edges. The water is clear and light greenish blue, and a boil is visible in the center of the pool. Thick, filamentous algae cover the majority of the spring bottom, and there are some native aquatic grasses in the spring pool. The spring is rich with fresh and salt water fishes and aquatic turtles. The Weeki Wachee River flows westward approximately 5 miles into the Gulf of Mexico. The river flows through low-lying, densely forested swamp. The nearest high ground east of the spring is rolling sand hills terrain and gently rises to 15 ft above the water level. All uplands and land adjacent to spring are developed. U.S. 19 is approximately 225 ft east of the spring.
Utilization - Weeki Wachee Spring is extensively developed into a tourist attraction that features underwater mermaid shows with a submerged observation area. It was purchased from private ownership by the Southwest Florida Water Management District (SWFWMD). The District leases the land to a private firm for the continuation of the mermaid shows. Shops and facilities are located all around the spring.
