Lake Paradise Report-2000
Lake Paradise was sampled at three sites on 23 May, 21 June, 24 July, 20 August, 19
September and 31 October, 1979 and on 10 May, 28 June, 26 July, 6 September and 19 October,
2000. Comparisons in this report will involve all of the dates sampled except the 20 August,
1979 date since no sample was taken in August, 2000 (Tables: Phytoplankton Totals-Site 1; Site

2000 using the sweep method. At some sites in 1979, it was not possible to filter a sufficient
amount of lake water to obtain optimum counts. In spite of this problem, numbers from 1979 are
included in the tables and graphs for each site as are the taxa present.
Phytoplankton reached their maximum density in both years for all three sites at Site 3 on 26
July, 2000 at 45,119/mL (Table: Phytoplankton Totals-Site 1; Site 2; Site 3; Phytoplankton
Totals-2000; Figures: Total Phytoplankton-Each Site; Total Phytoplankton-2000). Peak
production occurred at the other two sites on 26 July, 2000 (Site 1-30,387/mL; Site 2-
32,483/mL) as well. Blue-greens (Phylum Cyanophyta) dominated the phytoplankton on every
date in 2000 at Site 3 and every date but 10 May at sites 1 and 2 (Tables: Phytoplankton Totals-
2000; Figures: Total Phytoplankton-2000, Cyanophyta-2000). At sites 1 and 2 on 10 May, the
