Description - Sheppard Spring pool is slightly ovoid, measuring 90 ft east to west and 105 ft north to south. It is 25 ft deep near the center, with steep, sand sides. Two vents have been recognized. The water is clear bluish-green. Long filamentous algae cover the majority of the soft sand bottom. The spring has an abundance of fallen logs and a detritus layer covering most of the bottom. No boil was observed on the spring surface during the November 2002 visit. Plants and trees completely surround the spring pool and its run. The spring run averages 2 to 3 ft deep, 15 ft wide, and meanders southward for over a mile. It empties into Goose Creek Bay, approximately 4 miles west of the mouth of the St. Marks River. Sheppard Spring is a pristine, wild spring situated within the St. Marks National Wildlife Refuge. The surrounding Gulf Coastal lowlands are heavily forested with palm, hardwoods, and pine.

Utilization - The spring is undeveloped and remote, surrounded by National Wildlife Refuge land.
