Description Suwannee Blue Springs is a system of interconnected vents and pools spanning over 160 ft in length. Natural limestone bridges separate the pools. The pool furthest north measures 13.5 ft north to south, 4.0 ft east to west and 6.5 ft deep. Water flows from a limestone outcrop on the north edge of the pool. The pool bottom is limestone and the water is clear green. Algae and algae-coated aquatic vegetation are abundant in the pool. The spring water flows into the second pool, due south of the first pool. The second pool is oval and measures 23 ft north to south and 6 ft east to west. Water flows from various small cavities in the limestone around the pool. The water is clear blue and the pool does not have as much algae or aquatic vegetation as the first pool. The third pool, due south of the second pool, measures 32 ft by 15 ft. Water flows from cavities in the limestone on the east and west sides of the pool. The sand bottom pool has aquatic vegetation and sparse algae. The fourth and largest pool, measures 93 ft north to south and averages 7 ft wide. This pool appears to be discharging the most water though no boils are visible on any of the pool surfaces. Water from this last pool passes underground and feeds into the river by three different runs. The most significant run measures 10 ft long and averages 5 ft wide and 3 ft deep. High ground slopes up 4 ft above the spring pool surfaces and trails run along side the spring. The spring is surrounded by private land with a dense hardwood forest.
