Canal Spring

Location – Lat. 28° 02’ 05.23” N, Long. 82° 20’ 34.88” W (NW1⁄4 SW1⁄4 NE1⁄4 sec. 19, T. 28 S, R. 20 E). Canal Spring is located on the bottom of the Tampa Bypass Canal. It is 0.4 miles (0.64 km) upstream, or north, of the I-75 bridge. The spring is closer to the west side of the canal, near a constricted area where there is a weir. It is approximately 150 ft (45.7 m) northwest or inside of a barrier cable that prevents boat access through the bypass canal shallow area constriction.

Description – Canal Spring creates a circular boil approximately 10 ft (3.1 m) in diameter on the surface of the Tampa Bypass Canal. Depth measured over the vent is 15 ft (4.6 m). The spring appears as a circular slick spot on the surface of the canal waters. Clear spring water mixes with tannic canal water. The spring bottom cannot be seen. A boat can approach the spring from the south; however, there is no boat access past a cable barrier that is 150 ft (45.7 m) south of Double Spring. The spring was easily observed from a boat near the barrier or from the grassy banks of the canal during March 2003. The Tampa Bypass Canal was constructed to divert flood waters of the Hillsborough River around Tampa. Canal construction appears to have broken into underground conduits and tapped into the Floridan Aquifer System. At least three new springs were created during canal building - Canal Spring, Double Spring, and Last Spring. Each of these springs is visible as slick circular boils on the surface of the dark waters of the canal. Figure 97. Canal Spring (photo by R. Means).BULLETIN 66

Double Spring is located on the bottom of the Tampa Bypass Canal approximately 100 ft (30.5 m) south of the Harney Road bridge over the canal or approximately 600 ft (182.9 m) northwest of Canal Spring.

Description – Double Spring creates a circular boil approximately 10 ft (3.1 m) in diameter on the surface of the Tampa Bypass Canal. In the vicinity of the spring, the canal averages15 ft (4.6 m) deep. Clear spring water mixes with the darker waters of the canal. The bottom cannot be seen. The spring boil appears as a round slick spot on the surface of the canal waters and was easily observed during March 2003 from the grassy banks of the canal at a distance of nearly 300 ft (91.4 m) to the southwest. A boat can approach the spring from the south; however, there is no boat access past a cable barrier that is a few hundred feet south of Double Spring. The Tampa Bypass Canal was constructed to divert flood waters of theHillsborough River around Tampa. Canal construction appears to have broken into underground conduits and tapped into the Floridan Aquifer System. At least three new springs were created during canal building - Canal Spring, Double Spring, and Last Spring. Each of these springs is visible as slick circular boils on the surface of the dark waters of the canal. Figure 98. Double Spring (photo by R. Means).FLORIDA GEOLOGICAL SURVEY

496 Eureka Springs

Location – Lat. 28° 00’ 21.44” N, Long. 82° 20’ 45.15” W (NE1⁄4 SE1⁄4 NW1⁄4 sec. 31, T. 28 S, R. 20 E). Eureka Springs are situated within Eureka Springs Park in northeast Tampa. In Tampa heading west on I-4, take the Hillsborough Avenue exit and head east on Hillsborough Avenue. Immediately after exiting I-4 onto Hillsborough Road turn north (left) onto Eureka Springs Road and travel approximately 0.8 miles (1.3 km) to Eureka Springs County Park on the west (left) side of the road.

Description – Eureka Springs were inadvertently created in the mid 1900’s by the process of blasting for stump removal. At least 5 springs are within Eureka Springs Park. In August 2002, none of the springs were flowing. At that time, two stagnant spring pools werelocated within park grounds. The first spring is located approximately 150 ft (45.7 m) northnorthwest of the parking area. This spring occupies a man-made pool encircled by a shellcovered foot path. The spring pool is 100 ft in (30.5 m) diameter and was entirely covered in duck weed. During the time of visit, water in the spring pool was tea-colored. The spring run flows north into a canal and then through a culvert, eventually into the Tampa Bypass Canal. Another spring is situated along a boardwalk on the southwest side of the park, approximately 750 ft (228.6 m) southwest of the parking area. The park had its origins as a botanical garden of rare and exotic plants. Now it is operated as a county park with trails, including a 0.32 miles (0.52 km) boardwalk, a green house display, screened pavilion, and picnic area. In August 2002, park personnel reported that the springs had not been flowing regularly since the building of the Tampa Bypass Canal. Park personnel also report that Eureka Springs flow only during the summer rainy season.

Last Spring

497 Location – Lat. 28° 02’ 02.78” N, Long. 82° 20’ 33.30” W (SW1⁄4 SW1⁄4 NE1⁄4 sec. 19, T. 28 S, R. 20 E). Last Spring is located on the bottom of the Tampa Bypass Canal near the center of the canal. It is approximately 0.35 miles (.56 km) north of the I-75 bridge and just 150 ft (45.7 m) southeast of the boat access barrier cable across the canal. Last Spring can be reached by boat from the south.

Description – Last Spring discharges from the bottom of the Tampa Bypass Canal. Clearspring water mixes with tannic canal water over the vent. Turbulence from spring discharge creates a circular slick spot on the surface of the canal waters. Canal depths near the spring average 15 ft (4.6 m), but depth measured over the vent is 20 ft (6.1 m). The Tampa Bypass Canal was constructed to divert flood waters of the Hillsborough River around Tampa. Canal construction appears to have broken into underground conduits and tapped into the Floridan Aquifer System. At least three new springs were created duringcanal building - Canal Spring, Double Spring, and Last Spring. Each of these springs is visible as slick circular boils on the surface of the dark waters of the canal.

Lettuce Lake Spring

Turn east (left) onto this road and Lettuce Lake is approximately 500 ft (152.4 m) north of the SWFWMD office complex along US 301 in Tampa. The spring is located on the bottom of the lake. Figure 100. Lettuce Lake Spring (photo by R. Meegan).FLORIDA GEOLOGICAL SURVEY

498 Description – Lettuce Lake Spring is within Lettuce Lake. Lettuce Lake is a shallow, clear water lake that has a dark detritus covered bottom. The lake has a diameter of 150 ft (45.7 m). The spring vent is located in the center of the lake, where depth measures 8.8 ft (2.7 m). At the time of visit in March 2003, the spring apparently was not flowing and no boil was observed on the spring surface. A 6 ft (1.8 m) high berm runs along the south side of the lake. The natural spring run evidently used to run southward out of the lake prior to canal construction, but the berm now prevents the natural outflow. Instead, water exits the pool southwestward through a 200 ft (61 m) canal that is 1 ft (0.3 m) deep and 6 ft (1.8 m) wide. This canal enters another slightly larger canal that runs an additional 650 ft (198.1 m) south until entering the Tampa Bypass Canal.

Description – Thundering Springs consists of a cluster of small white sand boils that issue clear water into a circular pool 5 ft (1.5 m) in diameter and 0.6 ft (0.2 m) deep. A small spring run 15 ft (4.5 m) long, 2 ft (0.6 m) wide, and 0.4 ft (0.1 m) deep, flows southeast into Dead Creek. Dead Creek is impounded by a beaver dam, causing water to back up slightly into Thundering Springs. The spring and its run have sand and detritus bottoms. A steep gully that encompasses both pool and run has been created by erosion. The owner reports that spring flow has diminished over the years. Figure 103. Thundering Springs (photo by A.
