Two cyanobacteria genera, Woronichinia species and Coelosphaerium species, were detected in the concentrated plankton net tow-samples. However, these colonial genera were rare and not detected in the counts of the April 22nd whole water samples at either the North Bay Site or the Center Lake Site. The phytoplankton flora from the whole water samples was largely comprised of golden algae (Chrysophyta) and diatoms (Bacillariophyta) at the North Bay Site. At the Center Lake Site, golden algae, green algae (Chlorophyta) and diatoms were the major taxa observed. The golden algae Synura spp. was the dominant genus at both sites. Others included Mallomonas species and Uroglenopsis species. Planktonic diatoms included Aulocoseria species and Fragilaria species. At the Center Lake Site, the green alga Gleoecystis species was also an important component of the phytoplankton.
Secchi transparency was good and measured at 2.64m and 2.81m at the North Bay and Center Lake Sites, respectively. Similar Secchi transparencies were measured at the other two sites.
The water column was well mixed with differences in temperatures from top to bottom of <1°C at all four sites. All depths of all four sites on the lake had ample levels of oxygen which ranged from 9.61 to 10.65mg/L.
Specific conductance in surface waters (1m depth) was 193µS/cm at the North Bay Site and between 198 and 200µS/cm at the other three sites.
