Description Siphon Creek Rise is a spring 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 (14 m) north to south and 90 ft (27 m) east to west. Spring pool depth is 11.8 ft (3.6m).
The water is tannin stained, 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 it sways back
and forth in the powerful current. The adjacent west riverbank rises steeply to 2 ft (0.6 m)
above the water, exposing a fresh water shell marl. All land adjacent to the spring is low-
land river floodplain with cypress, gum, and maple.

Utilization Land around Siphon Creek Rise is pristine and owned by the SRWMD.
