Location – Lat. 30° 49’ 12.52” N, Long. 85° 14’ 41.62” W (SW 1⁄4 SW 1⁄4 NW 1⁄4 sec. 21, T. 5 N., R. 10 W.). Blue Hole Spring is located within the Florida Caverns State Park, 3 miles (4.8 km) north of Marianna. From the intersection of US 90 and SR 166 (Jefferson Street) in Marianna, travel north 2.6 miles (4.2 km) on SR 166 to the park entrance on the west (left) side of the road. Follow the park road 0.8 miles (1.3 km) then turn north (right) on Blue Hole Drive. Travel on Blue Hole Drive for 1.8 miles (2.9 km) to the spring and picnic

area.
Description – Blue Hole Spring pool is elongated and measures 159 ft (48.5 m) east to west and 258 ft (78.6 m) northwest to southeast. The depth of the spring pool is variable and measures up to 26 ft (7.9 m) (Rosenau et al., 1977). The spring has a sand bottom. Thick patches of filamentous green algae cover about half of the spring bottom. The water color is greenish and murky. No boil was visible on the water surface in June 2002. Water lettuce is abundant in the southeast portion of the pool. The west side of the pool has a limestone boulder wall with stairs leading down to a sandy swimming area. The south side of the spring has a wooden footbridge over the outflow channel. The east side has a limestone boulder wall and a wooden swimming dock. On the north side of the main pool, there is another much smaller pool that is separated from the main pool by a narrow land bridge. During the January 2002 visit, the water in the small pool was crystal clear and light blue,contrasting with the murky greenish water of the main spring pool. There is a wooden walkway that leads over the land bridge. The spring run discharges south approximately 1.6 FLORIDA GEOLOGICAL SURVEY

### Spring Lake Springs
The Florida Geological Survey sampled five second magnitude springs that flow into Spring Lake. Spring Lake actually is a 100-200 ft (30.5-61 m) wide spring run that forms at the confluence of Mill Pond Spring and Springboard Springs. Three other named springs enter into the lake (run) downstream, Double Spring and Black Spring from the south, and Gadsen Spring from the north. A low-lying swamp forest buffer surrounds the entire lake basin, and farther upslope becomes cleared farmland. Spring Lake discharges into Dry Creek, a dark water stream that flows approximately 13 miles (21 km) to the Chipola River. From the confluence, Dry Creek is clear and often flows over limestone.

Location - Spring Lake is located approximately 6.5 miles (10.5 km) southwest of Marianna and has one boat launch that is privately owned but open to the public. Due to extremely shallow spring run conditions, these springs are accessible by canoe or small boat only. From I-10, drive southwest 0.7 miles (1.1 km) on SR 276 to its intersection with SR 167. Turn south (left) on SR 167, travel 4.3 miles (6.9 km). Turn east (left) on Mystery Springs Road and travel 1.4 miles (2.3 km). Turn north (left) on a small track just before the end of the road. Follow this track down to the water and the boat launch. Directions to each spring are given in relation to Black Spring run where this boat launch is located.

### Location – Lat. 30° 41’ 55.40” N., Long. 85° 17’ 40.08” W. (SE 1⁄4 SW 1⁄4 SW 1⁄4 sec. 36, T. 4 N., R. 11 W.). Black Spring is 150 ft (45.7 m) upstream (west) of the boat launch on the south side of Spring Lake.
Description – Black Spring is also known as Black Hole (Rosenau et al., 1977). The spring pool is nearly circular, steep-sided, and deep. It measures 150 ft (45.7 m) in diameter, and is 49.1 ft (15.0 m) deep northeast of the pool’s center. Approximately 20 ft (6.1 m) below the surface on the northeast side, a 25 ft (7.6 m) vertical limestone wall leads down to the spring vent. The water is clear to slightly tannic but appears very dark. Black Spring derives itsname from its tendency to issue tannic water during times when all other springs associated with Spring Lake may be discharging clear water. This was the case during the March 2002 sampling visit; however, the water of Black Spring was clear and bluish two months later. Abundant aquatic vegetation, including water lettuce, exotic aquatic vegetation and algae
, covers the shallow areas around the perimeter of the spring pool. No boil was visible in March 2002. Black Spring flows through three separate stream channels. The main channel flows north, another northeast, and the other east, all under a swamp forest canopy and into Spring Lake. The north-flowing channel is approximately 150 ft (45.7 m) long, thenortheast-flowing and smallest channel is approximately 300 ft (91.4 m), and the east-flowing run approximately 350 ft (106.7 m). The runs are up to 50 ft (15.2 m) wide and 5 ft (1.5 m) deep. All immediate surroundings are low-lying with dense hardwood and cypress FLORIDA GEOLOGICAL SURVEY

There are large, thick mats of filamentous algae scattered about the pool among native aquatic vegetation with some exotic invasive aquatic plants. The spring discharges through a run as wide as the spring and flows for approximately 75 ft (22.9 m), where it splits into two channels, one flowing north and one flowing east. The majority of flow travels eastward approximately 200 ft (61 m) into a siphon that is estimated to have a depth of 15 ft (4.6 m). The northward run flows through a narrow channel a short distance into Spring Lake. Higher ground on the south side of the spring rises gently to approximately 8 ft (2.4 m) above the water. There is a wooden dock on the south side of the pool, and a private residence can be seen to the southwest on the higher ground. The area around the spring is within in a dense hardwood and cypress swamp forest.

Location – Lat. 30° 42’ 12.09” N., Long. 85° 17’ 18.42” W. (NW 1⁄4 NW 1⁄4 SE 1⁄4 sec. 36, T. 4 N., R. 11 W.). Gadsen Spring flows into Spring Lake from the north, 2100 ft (640 m) downstream from Black Spring Run.
Description – Gadsen Spring occupies a deep, conical, nearly circular to oval depression 120 ft (36.6 m) north to south and 141 ft (43 m) east to west. The depth of the spring pool measured over the vent is 43 ft (13.1m). The vent is located beneath a vertical limestoneledge that is slightly north of the pool’s center. The water is slightly murky with a greenish blue color. No boil on the pool surface was observed in March 2002. There is abundant native aquatic vegetation with some thick algae mats. Gadsen Spring discharges south 75 ft (22.9 m) through a narrow run that is shallow, approximately 1-3 ft (0.3-0.9 m) deep. The run then widens to about 100 ft (30.5 m) forming a pool that is approximately 150 ft (45.7 m) long and has dense aquatic vegetation. This pool is reported to be a sinkhole that takes some of the water (Rosenau et al., 1977). Continuing downstream southward, the run again narrows and flows swiftly for approximately 800 ft (243.8 m) through low-lying swamp forest until entering Spring Lake. A mowed grassy track accesses the spring on the north side. To the north, land rises very gently to a height of about 10 ft (3.1 m) abovethe lowlands. There is a small water-filled sinkhole to the north a short distance. All surrounding lands are forested.

Utilization

Description – Mill Pond Spring pool measures 126 ft (38.4 m) north to south and 150 ft (45.7 m) east to west. It occupies a conical depression. The depth measured near the center of the pool is 16.8 ft (5.1 m). The sides of the pool are steep and sandy, leading down to a deeper central area with limestone exposed in the spring vent. The water is clear and light blue. No boil was visible on the pool surface during the March 2002 visit. The pool has an abundance of exotic aquatic vegetation, except for the deeper central portion. Mill Pond Spring flows into uppermost Spring Lake on the southwest side via a 600 ft (182.8 m)-long, shallow spring run. The run averages 2 ft (0.6 m) deep. Private residences are present alongthe northwest side of the spring and the uppermost part of its run. The houses are situated on a gently sloping 8 ft (2.5 m) high ridge. The rest of the land surrounding the spring and its run is densely forested and mostly low-lying. High ground is also adjacent to the spring run on its south side approximately 400 ft (121.9 m) downstream from the spring.

Utilization

- The spring is located on private land and a portion of the water is extracted by a water bottling company. BULLETIN NO. 66

### Springboard Spring

Location

– Lat. 30° 42’ 26.64” N., Long. 85° 18’ 23.76” W. (NE 1⁄4 SE 1⁄4 NW 1⁄4 sec. 35, T. 4 N., R. 11 W.). Springboard Spring is on the northwest side of Spring Lake 0.9 miles (1.5 km) upstream from Black Spring run at the head of Spring Lake. At the head of Spring Lake, take the spring run that enters from the north and follow it approximately 1,000 ft (304.8 m) to the spring.
Description – Springboard Spring pool measures 78 ft (23.8 m) north to south and 60 ft (18.3 m) east to west. The spring issues from a deep crack in limestone near the center of the spring pool and is 18.4 ft (5.6 m) deep. Its water is clear and bluish. Aquatic vegetation including exotic aquatic vegetation and algae are abundant. A very slight boil was present in March 2002. It has two spring runs, one flowing southwest, and one flowing southeast. The southwest run, approximately 1,000 ft (304.8 m) long, is narrow, averages 2 ft (0.6 m)deep, and merges with Mill Pond Spring run to form upper Spring Lake. The southeastflowing run is approximately 125 ft (38.1 m) wide and averages less than 1 ft (0.3 m) deep. It has a soft sand and detritus-covered bottom with rich aquatic vegetation and freshwater mollusks. Approximately 800 ft (243.8 m) downstream, half of the southeast run flows into a swirling siphon approximately 50 ft (15.2 m) in diameter. The other half flows southward a short distance from the first siphon into another. During higher water levels, water flows past the siphons via an ephemeral stream channel southward to the northwest portion of Spring Lake. This intermittent channel was dry in March 2002. The immediate lands to the north of the spring are all low-lying and densely forested with mixed hardwoods and cypress. BULLETIN NO. 66

Group Location—Lat. 30° 20’ N., Long. 83° 59’ W. (Sections 2 and 12, T. 2 S., R. 3 E.). The Wacissa Springs Group is approximately 19 miles (30.6 km) southeast of Tallahassee and 1.2 miles (1.9 km) south of Wacissa. From the intersection of Tram Road and SR 59 in Wacissa, travel south on SR 59 approximately 0.7 mile (1.1 km) where SR 59 turns sharply to the west less than 1 mile (1.6 km) south of Wacissa. At this sharp right turn, a paved county road continues south (straight) and ends 0.6 miles (1 km) beyond at a county park and boat ramp situated on the east side of the head of the Wacissa River.
Group Description -The Wacissa Springs Group consists of at least 12 springs that give rise to the Wacissa River (Rosenau et al., 1977). Several springs are located at the head of the river near the county park. The rest are scattered along the upper 2 miles (3.2 km) of the river. Hornsby and Ceryak (2000) list 16 springs in this group. These include Wacissa, Big, Blue, Buzzer’s Log, Cassida, Garner, Horse Head, Log, Minnow, Thomas, JEF63991, JEF63992, JEF63993, JEF64991, JEF312991, and Acuilla springs. Land along the upper part of the river is low and flat, and it supports a lush mixed hardwood-palm forest.
Spring No. 2—Lat. 30° 20’ 23.59” N., Long. 83° 59’ 29.34” W. (SE1⁄4 SE1⁄4 NE1⁄4 sec. 2, T. 2 S., R. 3 E.). Spring No. 2 is located 15 ft (4.7 m) south of the diving board platform at thecounty park. There are multiple small vents near this spring. Spring pool diameter measures 45 ft (13.7 m) north to south. The maximum depth of the spring pool measures 8 ft (2.4 m). The spring pool is choked with exotic aquatic vegetation, and algae are present throughout the pool. There are no adjacent uplands. Land near the spring supports cypress FLORIDA GEOLOGICAL SURVEY

Location

– Lat. 30° 09’ 46.23” N., Long. 83° 14’ 35.06” W. (SW 1⁄4 NE 1⁄4 SW 1⁄4 sec. 5, T. 4 S., R. 11 E.). Allen Mill Pond Springs are located on SRWMD land approximately 8.5 miles (14 km) northwest of Mayo. The springs are on the west side of the Suwannee River at thehead of Allen Mill Pond. From the intersection of US 27 and SR 51 in Mayo, travel northwest on US 27 for approximately 4.8 miles (7.7 km). Turn north (right) on CR 251B and travel 3.7 miles (6 km) to the SRWMD sign for Allen Mill Pond on the east (right). Followroad to a parking area near the lower section of the spring run. The spring vent is approximately 0.6 miles (1.0 km) upstream from the mouth of the spring run. A footpath follows the west side of the run upstream to the spring.
Description – At least three spring vents occupy an elongated limestone fissure that spans 186 ft (56.7 m) east to west. The vent is a 2.5 ft (0.8 m) diameter hole in exposed limestoneand has a maximum depth of 8.6 ft (2.6 m). The fissure reaches a maximum width of approximately 40 ft (12.2 m). The banks are exposed limestone. The bottom is dark due to organic debris. The entire elongated spring pool was covered with a thick layer of duckweed in July 2002. Water quality was sampled from the westernmost spring vent in the fissure system. The sampled spring pool is estimated to be 15 ft (4.6 m) east to west and 8 ft (2.4 m) north to south. The depth of the sampled vent is estimated at 8 ft (2.4 m). Allen Mill Pond Springsdischarge southeastward from the east end of the fissure through a shallow run that averages about 1 ft (0.3 m) deep and 40 ft (12.2 m) wide. The spring run flows over scalloped limestone and rippled sand. There is an abundance of aquatic vegetation including exotic aquatic vegetation. Spring water is clear. There is a thick algal covering on limestone. FLORIDA GEOLOGICAL SURVEY

### Several additional springs feed the upper part of Allen Mill Pond Springs Run. Approximately 100 ft (30.5 m) downstream from the head springs, on the west side of the spring channel, a small spring discharges vertically near the bank. A small vent producing a slight boil also is present out in the middle of the shallow stream channel 20 ft (6.1 m) to the east. Continuing downstream about 100 feet (31 m) farther, another smaller spring run, that is approximately 80 ft (24.4 m) long, feeds in from the east side. At its head is a small spring that has a pool measuring 15 ft (4.6 m) in diameter. From this point, Allen Mill Pond Springs Run continues to flow southeast another 0.6 miles (1.0 km) into the Suwannee River.

Utilization – The spring and spring run are within heavily forested SRWMD land. A public access area is located along the west side of the lower part of the spring run.

Mearson Springs are located approximately 9 miles (14.5 km) east of Mayo along the southwest bank of the Suwannee River. From the intersection of US 27 and SR 51 in Mayo, head east on US 27 for approximately 6.6 miles (10.6 km) to the intersection with CR 251. Turn east (left) onto CR 251 and drive approximately 2 miles (3.2 km) until the road makes a 90 degree bend to the north. Continue north on CR 251 approximately 0.7 miles (1.2 km) to a boat landing at the end of the road. The spring are 0.8 miles (1.3 km)downstream from the boat ramp on SR 251. Mearson Springs occupy a southwest to northeast-trending cove surrounded by high banks along the southwest bank of the Suwannee River.
Description – Mearson Springs pool, which has three vents, measures 75 ft (22.9 m) southwest to northeast and 51 ft (15.5 m) southeast to northwest. The largest spring vent is southernmost, where a cavern opens beneath a limestone shelf. The depth over the largest spring measures 11.8 ft (3.6 m). The bottom is limestone and varying amounts of sand. Spring water is clear and slightly green, contrasting with the dark water of the Suwannee River.There are thick patches of algae but little to no other aquatic vegetation. Three springs producing prominent boils are oriented linearly along a 30 ft (9.1 m) long, north-south trending limestone fissure. On the southwest side, a wooden boardwalk and stairs lead down into thespring from the 15 to 25 ft (4.6 – 7.6 m) high banks. The short spring run discharges northeast about 30 ft (9.1 m) into the river. Land around the spring is privately owned and forested adjacent to the spring. Spring discharge is dictated by Suwannee River stage. Bare limeFLORIDA GEOLOGICAL SURVEY

From the intersection of US 27 and SR 51 in Mayo head east on US 27 for approximately 6.8 miles (10.9 km) to the intersection with CR 251. Turn east (left) onto CR 251 and drive approximately 2 miles (3.2 km) until the road makes a 90 degree bend to the north. Continue on CR 251 north approximately 0.7 miles (1.2 km) until the road comes to an end at a boat landing. The spring pool is approximately 0.25 miles (0.4 km) east of the CR 251B boat ramp on the Suwannee River.
Description – Owens Spring pool measures 114 ft (34.7 m) north to south and 87 ft (26.5 m) east to west. The pool is shallow, less than 8 ft (2.4 m) deep except in the deepest areaat the vent where it measures 31.3 ft (9.5 m) deep. The vent lies beneath a submerged limestone ledge on the southwest side of the pool. The water is clear bluish to slightly tannic. There is very little aquatic vegetation and the bottom is mainly rock and sand. There are thick patches of dark green filamentous algae covering more than half of the pool substrates.Owens Spring has steep limestone and sand banks. Its west and north banks rise vertically to approximately 20 ft (6.1 m) higher than the water surface. In July 2002, the spring had a short run with steep sandy banks. It flowed approximately 125 ft (38.1 m) northeast into a siphon. Also at this time, the spring was barely flowing, crystal clear, and averagedless than 1 ft (0.3 m) deep. During a prior visit in March 2002, the water level was approximately 5 ft (1.5 m) higher, flowing swiftly, and was slightly tannic. At higher water levels, Owens Spring flows overland through a lowland corridor leading to the Suwannee River. FLORIDA GEOLOGICAL SURVEY

The Ruth Spring is located 4 miles (6.5 km) northwest of Branford within the SRWMD Troy Spring Conservation Area. From the bridge over the Suwannee River in Branford, travel west and northwest for approximately 4.8 miles (7.7 km) on US 27, then turn north (right) on CR 425. Drive 1 mile (1.6 km) and turn east (right) into the Troy Spring Conservation Area. Follow dirt road 1.1 miles (1.8 km), turn north (left) on another dirt road and continue 0.1 mile (0.2 km) to the spring.
Description – Ruth Spring pool measures 75 ft (22.9 m) in diameter north to south and 51 ft (15.5 m) east to west. The vent is located beneath a limestone ledge on the west side of the pool, where the depth measured 5.9 ft (1.8 m). There is a wooden erosion control wall built along the west side of the depression approximately 3 ft (0.9 m) higher than the spring water level at the time of the visit. The bottom of the spring pool is mainly exposed sand. Limestone crops out around the pool edge. The water is clear, with a slight greenish hue and a small boil present on the pool surface near the vent. There is very little aquatic vegetation and algae. The shallow, sand-bottomed spring run travels eastward approximately 550 ft (167.6 m) and flows into the Suwannee River. On the south and west sides of the spring, the land rises steeply to approximately 20 ft (6.1 m) above the lowlands that contain the spring and its run. All lowlands and adjacent uplands are forested. There is a dirt access road and small parking area near the west side of the spring. Ruth Spring also is locallyknown as Sulfur Spring. Local swimmers reported that the spring often has a slight hydrogen sulfide odor, but this was not the case in March 2002. FLORIDA GEOLOGICAL SURVEY

Turn north (right) on CR 425 and travel 1.2 miles (1.9 km) to the state park entrance on the right.
Description

- Troy Spring issues from a depression with vertical limestone walls. The pool diameter measures 138 ft (42.1 m) north to south and 118 ft (36 m) east to west. The pool depth is 61 ft (18.6 m). The spring run is about 325 ft (99 m) long and flows in a straight path eastward to the Suwannee River. A thick layer of dark green filamentous algae covers nearly all aquatic substrates. There is little to no other aquatic or emergent vegetation. Water color is clear and greenish. Limestone is exposed around the spring pool and has a scalloped appearance. High ground surrounds the spring and rises to approximately 18 ft (5.5 m) above water surface. The uplands are generally forested with pines and hardwoods. The Springs Fever website notes that at the lower end of the run lie the keel timbers/ribs of the 19 th 

### century steamship, Madison, which was purposely sunk in the run during the Civil War to prevent it from falling into Union hands. The ribs resemble railroad ties. There is a nearby cabin to the south. An underwater cave system has been mapped at Troy Spring.

Utilization— Troy Spring was recently acquired by the state park system. It has been developed with parking area, restrooms, a cement and wooden ramp leading down to the FLORIDA GEOLOGICAL SURVEY

### Apopka Spring

Location

– Lat. 28° 33’ 59.77” N., Long. 81° 40’ 50.41” W (NW 1⁄4 SW 1⁄4 SE 1⁄4 sec. 14, T. 22 S., R. 26 E.). Apopka Spring is located on the southwest side of Lake Apopka in Gourd Neck, 2 miles (3.2 km) south of Monteverde and is accessible only by boat. From Clermont head east on SR 50 approximately 3.5 miles (5.6 km) to the intersection with CR 455. Turn north (left) onto CR 455 and travel approximately 4.2 miles (6.8 km) to the town of Monteverde. Turn east (right) once in Monteverde and follow signs to the boat landing approximately 0.5 mile (0.8 km).
Description – Apopka Spring occupies an open cove on the northwest side of Gourd Neck of Lake Apopka. The circular spring pool measures 180 ft (54.9 m) in diameter, while the larger spring cove containing the spring measures 450 ft (137.2 m) north to south and 360ft (109.7 m) east to west. The vent is in the center of the deep, bowl-shaped spring depression where the depth measures 45 ft (13.7 m). The spring bottom is a mixture of sand and dark organic matter. Cloudy lake water quickly turns to clear spring water as the spring is approached. There is some exotic aquatic vegetation along the sandy slopes of the spring depression. The spring produces a large boil, and suspended particles can be seen within the clear water column. The spring cove is shallow around the perimeter with an organic, mucky bottom and emergent vegetation. Gourd Neck is buffered by marsh and lowland swamp forest on its west side before giving way to sand hills with extensive agriculture. Theeast side of Gourd Neck is bordered by a sand hill peninsula with planted pines. An underwater cave system has been recognized in this spring. FLORIDA GEOLOGICAL SURVEY

### Bugg Spring

Location – Lat. 28° 45’ 07.15” N., Long. 81° 54’ 05.46” W. (SE 1⁄4 NW 1⁄4 NW 1⁄4 sec. 15, T.20 S., R. 24 E.). Bugg Spring is located 0.4 miles ( 0.6 km) northwest of Okahumpka on privately owned property.
Description – Bugg Spring is a large, very deep, circular spring situated south of Lake Denham. The spring pool measures 396 ft (120.7 m) north to south and 372 ft (113.4 m) east to west. There is a vertical limestone ledge a few feet out from the south shore, and depths beyond the ledge eventually reach 170 ft (51.8 m). The water is clear and blue-greenish. Noboil was observed on the pool surface during April 2002. There is very little aquatic vegetation, but algae are abundant. A large U.S. Navy platform supporting a laboratory for field instrument calibration is floating in the middle of the spring with a walkway attached to the northeast shore. The slow-moving spring run flows north approximately 0.8 mile (1.3 km) into Helena Run, the outflow of Lake Denham. Lands immediately surrounding the spring are low-lying and densely forested. The landowner’s residence is to the south, where the land begins to rise, eventually becoming rolling sand hills used primarily for agriculture.

Utilization - Bugg Spring is leased to the U.S. Naval Research Laboratory for underwater sound reference work. The spring is on private property. FLORIDA GEOLOGICAL SURVEY

### Natural Bridge Spring

Location

– Lat. 30° 17’ 06.67” N., Long. 84° 08’ 49.64” W. (SW 1⁄4 NE 1⁄4 NE 1⁄4 sec. 29, T. 2S., R. 2 E.). Natural Bridge Spring is located on private property 13.5 miles (22 km) southeast of Tallahassee, or 0.3 miles (0.5 km) east of the Natural Bridge State Historic Site.
Description – Natural Bridge Spring pool measures 66 ft (20.1 m) north to south and 75 ft (22.9 m) east to west and it is situated in a conical depression. Spring depth measured 33.1 ft (10.1 m) out from the north bank. The water is clear and blue-greenish. There is muchalgae growing on the limestone substrate. The spring run is as wide as the spring pool, averages approximately 6 ft (1.8 m) deep and flows swiftly over limestone and sand bottom. Themajority of spring water flows southwest for approximately 0.25 miles (0.4 km), disappearing into a siphon approximately 300 ft (91.4 m) east of Natural Bridge; however, nearly 200 ft (61 m) downstream from the spring, a small channel splits off from the main spring run and travels westward approximately 1,000 ft (304.8 m) into the St. Marks River. At Natural Bridge, the St. Marks River flows into a siphon. The river continues undergroundto the south. Its underground course is dotted with sinkholes and karst windows for approximately 0.6 miles (1 km) until it re-emerges as St. Marks River Rise (or St. Marks Spring). Natural Bridge Spring flows into a siphon that is approximately 250 ft (76.2 m) east of the St. Marks River siphon. It is suspected that Natural Bridge Spring and the St. Marks Rivermerge underground in the vicinity of Natural Bridge. There may be a cave system associated with this spring.

### Rhodes Springs

Rhodes Springs are a group of karst windows that may be exposures of the same subterranean conduit system. Flow from all Rhodes Springs moves east and south toward the Natural Bridge area and may converge underground with the subterranean St. Marks River somewhere above St. Marks River Rise. The Florida Geological Survey sampled three of thekarst windows within this group. The springs are located on private property approximately 13 miles (21 km) southeast of Tallahassee. From the intersection of SR 363 (WoodvilleHighway) and Natural Bridge Road in Woodville, head east on Natural Bridge Road approximately 5.6 miles (9 km) to the intersection with Old Plank Road. Turn south (right) onto Old Plank Road and the spring run will be immediately on the west (right) side of the road. There is an unpaved pull out area near the spring run.

Half of the surfaces of both the spring and siphon are covered with duckweed. Abundant native aquatic vegetation and some algae occur on the sand and limestone substrates. Exotic aquatic vegetation also is present but not dominant. Noboil is present on the surface of the spring pool, but there is swift current in the stream channel. To the west, the ground rises gently to approximately 6 ft (1.8 m) above the water level. The rest of the nearby lands are low-lying and densely forested with mixed hardwoods and cypress. Rhodes Spring No. 1 is located down gradient from Rhodes Springs No. 2 and 4, and is suspected to be a downstream window into the same conduit system.

RHODES SPRING NO. 2 Location

– Lat. 30° 17’ 11.26” N., Long. 84° 09’ 35.84” W. (SW 1⁄4 NW 1⁄4 NW 1⁄4 sec. 29, T. 2 S., R. 2 E.). Rhodes Spring No. 2 is located 330 ft (100.6 m) southwest of the intersection between Old Plank Road and Natural Bridge Road.

Description – Rhodes Spring No. 2 is a karst window system with two springheads (2a and 2b). Rhodes Spring 2a is approximately 100 ft (30.5 m) south of 2b, and it flows eastward for about 50 ft (15.2 m) until the similar-sized No. 2b feeds in on the north side. RhodesSpring No. 2a has a circular spring pool measuring approximately 35 ft (10.7 m) in diameter. It has a depth of 12.0 ft (3.7 m), and the water is clear. The bottom of the springs and their short runs is sandy with some exposed tree roots in bluish clay. There are small boils on the surface of both spring pools. Combined flow is due east approximately 200 ft (61 m)into a siphon that is adjacent to the west shoulder of Old Plank Road just south of the intersection with Natural Bridge Road. The area is under the dense canopy of a mixed hardwood and pine forest. The surrounding land is low-lying, and numerous sinkholes are located to the north and west of the springheads. Planted pine flatwoods are 300 ft (91 m) northward, on the north side of Natural Bridge Road. Rhodes Spring No. 2 is up gradient from the other karst windows in the Rhodes Spring system.

RHODES SPRING NO. 4 Location

– Lat. 30° 17’ 00.71” N., Long. 84° 09’ 26.18” W. (NE 1⁄4 SW 1⁄4 NW 1⁄4 sec. 29, T. 2 S., R. 2 E.). Rhodes Spring No. 4 is located 675 ft (205.7 m) west southwest of Rhodes Spring #1.
Description – Rhodes Spring No. 4 is a karst window that flows 190 ft (57.9 m) to the southeast. The circular spring pool, at the northwest end of the karst window, measures 45 ft (13.7 m) in diameter. The depth measures 16 ft (4.9 m). The water is clear with a light greenish hue. There are some emergent plants along the shore and a thin layer of algae throughout the pool. The banks rise steeply to approximately 6 ft (1.8 m) above the water level. The surrounding karst plain is flat and heavily forested. Planted pine flatwoods areto the north, and swampy lowland is south. Rhodes Spring No. 4 is the middle karst window of the Rhodes Spring karst window system.

### St. Marks River Rise

Location—Lat. 30° 16’ 33.77” N., Long. 84° 08’ 56.16” W. (NE 1⁄4 SW 1⁄4 SE 1⁄4 sec. 29, T. 2 S., R. 2 E.). St. Marks River Rise is located 0.6 miles (0.9 km) south of Natural Bridge Battlefield Park. The river rise is surrounded by private property but can be accessed by small boat. From the intersection of US 319/SR 263 (Capital Circle Southeast) and SR363 (Woodville Highway), drive south on SR 363 14.7 miles (23.7 km) to US 98. Turn east (left) and go 2.5 miles (4 km) to the public boat ramp sign on the east side of the St. Marks River and north side of US 98. St. Marks River Rise is 6.5 miles (10.5 km) upstream from the boat ramp.
Description -St. Marks River Rise issues from an elongated fracture in the limestone. The river rise pool diameter measures 315 ft (96 m) east to west and 195 ft (59.4 m) northwest to southeast. Just south of the vent, the St. Marks River widens to 420 ft (128 m) northwest to southeast. The vent is nearly circular and its diameter is approximately 90 ft (27.4 m). St. Marks River Rise pool depth measures 62 ft (18.9 m). The vent is limestone with almosta sheer drop on northeast side from 18 ft (5.5 m) to 48 ft (14.6 m). Water was clear and colorless to light blue. Area near the vent is choked with exotic aquatic vegetation, and there is abundant native aquatic grass farther downstream. Some water hyacinth is present. Uplands near the spring rise gently to approximately 5 ft (1.5 m) above water level and are generally forested with a mix of pines, oaks, and cabbage palms.

Utilization—Land around the river rise is privately owned and access is restricted to dirt 4 x 4 tracks. A pipe leads into the vent from the north. BULLETIN NO. 66
