Telford Spring is situated along the east side of the Suwannee River at the head of a cove surrounded by steep sandy banks. The spring emerges from two caves within scalloped limestone whose passages connect underneath a 5 ft (1.5 m) by 7 ft (2.1 m) wide natural limestone bridge. The natural bridge over the spring was about 1 ft (0.3 m) higher than water level in April 2002. The main pool measures 66 ft (20.1 m) north to south and 51 ft (15.5 m) east to west and has a prominent boil. The maximum depth of the spring pool is 11.3 ft (3.4 m) over the vent. The spring and its run have a sand and limestone bottom. The water color is greenish and clear. Algae are sparse and there is virtually no aquatic vegetation. The short, shallow, 1 ft (0.3 m), spring run flows approximately 75 ft (22.9 m) into the dark, tannic waters of the Suwannee River. Land on the 12-15 ft (3.7-4.6 m) high, eroded banks supports a dense mixed hardwood/pine forest and there is a large unpaved parking area around the perimeter of the spring pool. A sinkhole with a clear water pool is located 150 ft (45.7 m) north of the spring across the sand access road. Spring water levels are directly tied to Suwannee River fluctuations.

Bill’s Description:

Shallow cave – 60’ or less. This sits right on the river. Great for penetration diving. This cave system changes every 500’ feet.
