Siphon Creek Rise is the reemergence of Siphon Creek that discharges from a single vent along the west bank of the Santa Fe River in the mouth of Siphon Creek. The spring pool measures 45 ft (13.7 m) north to south and 90 ft (27.4 m) east to west. Spring pool depth is 11.8 ft (3.6 m). The water is tannin colored, like that of the adjacent Santa Fe River. There is a voluminous boil over the vent. Native aquatic grass grows in the vicinity of the vent and sways back and forth in the powerful current. The adjacent west riverbank rises steeply to 2 ft (0.6 m) above the water, and fresh water shell marl is exposed. All land adjacent to the spring is lowland river floodplain with cypress, gum, and maple.
Siphon Creek Rise is approximately 4 miles (6.4 km) south of Fort White on the Santa Fe River. From the intersection of US 27 and SR 47 in Ft. White, drive south on SR 47 approximately 4.5 miles (7.2 km) to the boat launch on the northwest side of the Santa Fe River. The river rise is upstream approximately 0.75 mile (1.2 km) on the south of the river at the mouth of Siphon Creek.
