Troy Spring issues from a depression with vertical limestone walls. The pool diameter measures 138 ft (42.1 m) north to south and 118 ft (36 m) east to west. The pool depth is 61 ft (18.6 m). The spring run is about 325 ft (99 m) long and flows in a straight path eastward to the Suwannee River. A thick layer of dark green filamentous algae covers nearly all aquatic substrates. There is little to no other aquatic or emergent vegetation. Water color is clear and greenish. Limestone is exposed around the spring pool and has a scalloped appearance. High ground surrounds the spring and rises to approximately 18 ft (5.5 m) above water surface. The uplands are generally forested with pines and hardwoods. The Springs Fever website notes that at the lower end of the run lie the keel timbers/ribs of the 19th century steamship, Madison, which was purposely sunk in the run during the Civil War to prevent it from falling into Union hands. The ribs resemble railroad ties. There is a nearby cabin to the south. An underwater cave system has been mapped at Troy Spring.
