Oasis Spring has a clover-shaped pool that measures 20 ft (6.1 m) wide and 22 ft (6.7 m) long. Its depth is 9.1 ft (2.8 m). The spring has cloudy water and no boil was present on the water surface in March 2003. It has a limestone bottom with some sand and sparse amounts of algae. Oasis Spring is on the riverbank of the Santa Fe River. A short spring run flows northwest about 4 ft (1.2 m) before entering the river. The spring run is 6 ft (1.8 m) wide and 1.1 ft (0.3 m) deep. The high ground surrounding this spring ranges from 1 to 8 ft (0.3 to 2.4 m) above the water level. The area to the southeast appears to be an old run that is now filled in with grass and shrubs. Hornsby and Ceryak (1998) mention that the spring may have been dredged in the past. Oasis Spring is surrounded by forested private property. Discharge on September 9, 1997 measured 1.02 ft3/s.
