Gator Spring has an elongated spring pool measuring 114 ft (34.7 m) northeast to southwest and 195 ft (59.4 m) north to south. The spring pool ranges from 3 ft (0.9 m) to 7 ft (2.1 m) deep. This spring bottom is sand. The pool has been altered to form a swimming pond; however, there is no evidence of recent use. There was no boil over the spring vent in the west side of the pool in January 2003. The water is clear with a greenish hue. Algae are both suspended in the water and attached to substrates. There is aquatic and emergent vegetation in and around the spring pool. There is a small culvert on the northwest side of the pool that drains the meager flow from the spring and channels the water through an earthen dam into the spring run. Some limestone boulders occur near the culvert and the vent. Gator Spring Run is a small, narrow, sand-bottomed stream that flows southwest for approximately 350 ft (106.7 m) and enters upper Magnolia Spring Run, just below Magnolia Spring. There is a private residence approximately 350 ft (106.7 m) west of Gator spring, or 300 ft (91.4 m) north of Magnolia Spring. Formerly cleared land surrounding Gator Spring is now overgrown with dense brush.
Gator Spring is located 0.8 miles (1.3 km) west of Aripeka near the head of the south fork of Hammock Creek.
