Running Springs consist of a pair of separate spring areas (East Running Springs and West Running Springs) that discharge from small cavities at the base of an approximately 20 ft (6.1 m) high limestone bank on the northeastern side of the Suwannee River. The two springs occur in depressions in the river bank that are separated by approximately 150 ft (45.7 m). East Running Springs was sampled for water quality and was approximately 2 ft (0.6 m) above the adjacent Suwannee River during the March 2002 visit. The spring pool is oblong and measures 70 ft (21.3 m) north to south and 50 ft (15.2 m) east to west. Its depth ranges from 2 to 6 ft (0.6-1.8 m). The pool bottom is sand and limestone. The water is clear and bluish. There is no aquatic vegetation, and algae occur on portions of the sand and limestone substrates. It has a short southwestward flowing run that is approximately 25 ft (7.6 m) long. The run cascades over a 2 ft (0.6 m) high limestone ledge into the river. East Running Springs has multiple boils within the northeast end of the pool. There are several spring rivulets emerging from the base of the high banks into the northeast end of the pool. There is another spring located in the Suwannee River that creates a prominent boil along the riverbank just 15 ft (4.6 m) upstream of the mouth of East Running Springs. Divers report this spring to be connected to the East Running Springs run through an underwater cavern. West Running Springs is smaller and has a run that is approximately 150 ft (45.7 m) long. The run flows southwestward under a small land bridge then into the river. Rosenau et al. (1977) report steep limestone walls, natural limestone bridges and numerous vents at these springs. The high ground above Running Springs harbors a mixed hardwood and pine forest with some private landscaping intended to reduce erosion.
Running Springs is located on private land, 4.3 miles (6.9 km) northeast of Mayo. From Mayo, drive 3.3 miles (5.3 km) north on SR 51 to the boat ramp. The spring runs flow in from the northeast side of the Suwannee River, 4.3 miles downstream (east) from the boat ramp on SR 51.
