MonitoringLocationDescriptionText East Bay is separated from Apalachicola Bay by 2 bridges & a causeway (located to the north of the bay proper). East Bay is 8.2 km long, avg depth of 1.0 m MHW, avg width of 1.8 km. Tides in East Bay are mixed and range from 0.3 m to 1.0 m. The datalogger/nutrient sampling site is in the upper reaches of East Bay. The tower location for the two East Bay dataloggers (ES and EB) is 29.7858 N, 84.8752 W. At the sampling site, the depth is 2.2 m MHW & the width of the bay is 1.0 km. The "mixed tides" can range from 1-5 tides during a 24-hour period-not evenly distributed throughout the day. At the East Bay surface site the meter probes are 0.5 meters below the surface (or 1.7 m off bottom sediment) and salinity ranges from 0 psu to 30 psu with long term (1995 - 2017) avg salinity of 9.9 psu. The freshwater input is tannic and dark colored. Flows vary with local rainfall and are not quantified due to diverse sources of runoff. Bottom habitat at this bay site is soft sediment, primarily silt and clay, with no vegetation present. Dominant marsh vegetation near the sampling site (~300 meters away) is needle rush grass, swamp sawgrass, smooth cordgrass. Dominant upland vegetation is primarily pineland forests including slash pine, saw palmetto, and sand pine. Upland land use includes conservation and silviculture use with single family residential in the lower East Bay area. The sampling site is influenced by local runoff from Tate's Hell Swamp, the East Bay marshes, and distributary flow, some of which comes from the Apalachicola River via the East River. Tate's Hell Swamp was ditched, diked, and altered in the late 1960's and early 1970's by timber companies. These changes shortened the drainage period and allowed increased runoff with a concomitant decrease in pH and increase in color, which had a drastic effect on the biological communities in East Bay. Restoration of Tate's Hell Swamp began in 1995 to reduce non-point source runoff and restore historic sheet flow.
