Citrus Blue Spring has a roughly circular pool that measures 120 ft (36.6 m) in diameter. The east side of the spring pool is partly enclosed by a man-made, five foot high dike. The spring depression is relatively shallow and uniform except at the vent in the center where depth measures 22 ft (6.7 m). A slight boil was observed over the vent during October 2002. The color of the water is bluish-green, and the sand bottom has substantial aquatic grass cover with sparse algae. Spring flow is directed northwestward through a 30 ft (9.1 m) wide man-made canal, eventually discharging into the Withlacoochee River approximately 0.4 miles (0.6 km) downstream. The canal has a sand bottom with abundant detritus as well as abundant aquatic vegetation. Before the dike was constructed, the spring apparently discharged eastward approximately 150 ft (45.7 m) into the river. The spring is within the forested Withlacoochee River floodplain. The spring reportedly has an extensive cavern system that opens southward to a depth of at least 180 ft (54.9 m) below the spring surface.
Citrus Blue Spring is surrounded by private property and is used locally for swimming.
Citrus Blue Spring is located along the Withlacoochee River approximately 10 miles southeast of Dunnellon. From the US 41 bridge over the Withlacoochee River in Dunnellon travel south on US 41 approximately 1.3 miles to the intersection with CR 39. Head east (left) on CR 39 and travel approximately 7.6 miles to the intersection with CR 200. Head northeast (left) and travel 0.1 mile to the bridge over the Withlacoochee River at Stokes Ferry. A boat launch is on the southeast side of the river. The spring can be accessed by boating 3 miles upstream from the CR 200 bridge in Stoke's Ferry. The spring is situated on the south (right) side of the river.
