Bugg Spring is a large, very deep, circular spring situated south of Lake Denham. The spring pool measures 396 ft (120.7 m) north to south and 372 ft (113.4 m) east to west. There is a vertical limestone ledge a few feet out from the south shore, and depths beyond the ledge eventually reach 170 ft (51.8 m). The water is clear and blue-greenish. No boil was observed on the pool surface during April 2002. There is very little aquatic vegetation, but algae are abundant. A large U.S. Navy platform supporting a laboratory for field instrument calibration is floating in the middle of the spring with a walkway attached to the northeast shore. The slow-moving spring run flows north approximately 0.8 mile (1.3 km) into Helena Run, the outflow of Lake Denham. Lands immediately surrounding the spring are low-lying and densely forested. The landowner’s residence is to the south, where the land begins to rise, eventually becoming rolling sand hills used primarily for agriculture.
Bugg Spring is located 0.4 miles ( 0.6 km) northwest of Okahumpka on privately owned property.
