Apalachicola River (Sites 11 and 12) 



Location - Site 11 is located on the west bank of the Apalachicola 

 River, immediately south of the Florida Highway 20 bridge, 1 . 6 km east 

 of Blountstown in Calhoun County, Florida. Site 12 is located on the 

 east bank of the river, 4.8 km north of Bristol in Liberty County, 

 Florida. Reference USGS maps Blountstown, Florida, N3022 . 5-W8500/7 . 5 , 

 1945, and Bristol, Florida, N3022 . 5-W8452 . 5/7 . 5 , 1945, respectively. 



Hydrology data - Twenty years of hydrology data for Site 11 were ana- 

 lyzed for a gauge located . 8 km south of Highway 20 bridge at the Neal 

 Lumber Company Landing. Hydrology data for Site 12 were analyzed from 

 data from a previous study (Leitman et al . 1984). 



General vegetation - Vegetation for both sites ranges from Nyssa 

 aquatica- -dominated swamps at lower elevations to Nyssa sylvatica- 

 Juglans nigra-Sassafras albidum dominated associations at higher eleva- 

 tions. Intermediate plant communities consist of Fraxinus caroliniana, 

 Gleditsia aquatica , Quercus lyrata , Carya aquatica , Ulmus americana , 

 Helia azederach, Celtis laevigata , and Quercus nigra. 



Soils and climate - Soil series range from Bibb at lower elevation to 

 Ochlochonee at higher elevations. Soils series occurring at intermedi- 

 ate elevations were Chastain, Enoree, Jena, and Chewacla. Average 

 annual rainfall is 137 cm, and the average growing season is 267 days. 



Delineated zones - Zones delineated for site 11 were 2, 3, 4, and 5. 

 Essentially all of Zone 6 has been developed for agriculture. Zones 

 delineated for site 12 were 4, 5, and 6. The hydrology of Zones 2 and 3 

 had been altered by an extensive network of beaver dams and was not 

 reliable.
