1971). Productivity measured during the 3 h exposure was expanded to mean daily productivity (mgC/ m'·day) using solar radiation data obtained at the site during the exposure and total daily radiation measured in Winfield, Alabama by a cooperative observer for the National Oceanic and Atmospheric Administrations (NOAA) (Table 10-4). Phytoplankton densities in 1995 ranged from a low of357 organisms/ml at station I during the spring 1995 (Table 10-36) to 2,294 organisms/ml at station 3 during the summer 1995 (Table 10-37). Highest densities occurred during the summer and fall and lowest densities during the spring. Seasonal mean densities were usually similar among stations within a season and mean embayment densities were similar to nearby mainstem station densities (Tables 10-35, 10-36, 10-37 and 10-38, Fig. 10-8). In 1995, seasonal mean phytoplankton densities were about twice what they were at the same locations in 1986. On an annual basis, mean densities were significantly (P < 0.05) higher in 1995 at all locations except at mainstem at Duncan's Creek (station 5) and mainstem downstream from the confluence ofSipsey Fork and Brushy Creek (station 7) (Fig. 10-9). Numerical dominance was shared by green algae (Division Chlorophyta) and diatoms (Division Chrysophyta) at mainstem sampling stations (Fig. 10-10). Diatoms were generally more abundant in spring months and green algae more abundant in summer and fall months. The blue-green algae (Division Cyanobacteria) were the third most abundant algal Division. Euglenoids (Division Euglenophyta) and dinoflagellates (Division Pyrrhophyta) were combined into an "others" category. In 1986, green algae made up a larger proportion ofthe plankton community than they did in 1995. The diatoms increased in relative abundance in 1995 and seemed to dominate further into the summer and fall seasons than they did in 1986 (Fig. 10-10). This pattern ofalgal dominance is common in Alabama lakes (Bayne et al. 1993a, 1993b, and 1995). 103
