OPEN FILE REPORT NO. 85 Econfina Creek at Gainer Springs is owned by Patronis, Inc (out of Panama City, Fla). The east side of the creek is owned and managed by the NWFWMD. GAINER SPRING NO. 1C Lat. 300 25' 39.6" N, Long. 850 32' 46.0" W (SW14 NW14 SE14 sec. 4, T. 1 S, R. 13 W). Gainer Spring Nos. 1A, 1B, and 1C form a 820 ft (250 m) long spring run that enters Econfina Creek on the east side directly across from Spring No. 2. Spring No. 1C is the first spring encountered approximately 495 ft (150 m) upstream from the creek, and its pool is adjacent to the run on the southeast side. Spring pool dimensions are approximately 72 ft (22 m) east to west and 33 ft (10 m) north to south. Water issues upward from a vertical tunnel in the limestone. Shell and sand particles are suspended in the spring flow. Pool depth is 20 ft (6.1 m) measured over the vent opening. There is very little aquat- ic vegetation, however, algae patches in spring pool are common. The adjoining, swampy lowlands are heavily forested with cypress and mixed hardwoods. The nearest uplands to the southeast support a mixed hardwood and pine forest. There is no high ground adjacent to the spring pool. GAINER SPRING NO. 2 Lat. 300 25' 38.6" N, Long. 850 32' 54.0" W (SW/4 NE14 SW/4 sec. 4, T. 1 S, R. 13 W). This spring is located directly across from the mouth of Gainer Spring No. 1 run along the west side of Econfina Creek. Spring water issues forcefully from the base of the riverbank and forms a pool along the edge of the creek. Pool diameter is approx- imately 60 ft (18 m) east to west and 62 ft (17 m) north to south. Pool depth is 5 ft (1.5 m). Vent diameter is approximately 5 ft (1.5 m). There is little or no aquatic vegetation, but patches of dark green algae are present. The water is light greenish blue. A concrete wall forms the south side of the spring pool. Two parallel pipes that extract drinking water run from inside the spring vent toward the top of the bluff and beyond. There are at least three other smaller vents issuing from the bank just above this spring. A 23 ft (7 m) high bluff meets Econfina Creek at Spring No. 2. A mixed hardwood and pine forest inhabits the bluff face and high ground. GAINER SPRING NO. 3 Lat. 300 25' 44.3" N, Long. 850 32' 53.9" W (NE/4 NE14 SW/4 sec. 4, T. 1 S, R. 13 W). This spring is located along the west side of Econfina Creek, and is about 655 ft (200 m) upstream of Spring No. 2. It is at the head of a 325 ft (100 m) long spring run. There are at least three vent complexes in the combined spring pool. The depression is large and mostly shallow with a sandy bottom and limestone boulders. The combined spring pool diameter is about 305 ft (93 m) east to west and 125 ft (39 m) north to south. There is a forested island in the center of the combined spring pool. Some emergent vege- tation exists along the pool's shores, but there is very little aquatic vegetation. Dark green algal mats are ubiquitous throughout the bottom of the spring pool. The western vent issues out of a limestone sidewall and has a small boardwalk nearby. The north vent where water quality was sampled is the largest and deepest. This spring is about 15 ft (5 m) south of a wooden wall presumably constructed for shore erosion management. Light greenish blue water issues vertically from the bottom of a 16 ft (5 m) diameter conical depression and pro- duces a boil at the surface. The depression is 7.4 ft (2.3 m) deep over the vent. Vent diam- eter is about 1.5 ft (.5 m). On the eastern side of the combined spring pool, there are at least 3 other vents. Uphill to the north, there are picnic tables under a pavilion in a grassy open- ing. The rest of the uplands adjoining the spring pool to the west are forested with mixed hardwoods and pines.
