at 61/mL. Of the 13 taxa in the 3 May, 2005 sample taken at Site 5, the same three that were
numerous at Site 1 and in the highest densities at Site 4 were numerous (Table: 5/3/2005-Site 5).
A. falcatus var. acicularis was in a density of 143/mL, the Cosmarium sp. seen at the other two
sites was at 122/mL and K. lunaris var. lunaris was at 245/mL. Seven species were in the 23
June, 1997 sample with none of the seven in the numerous category. Carteria multifilis and
Schroederia setigera were the two species in highest density with each at 74/mL. At Site 1 on 6
June, 2005, 15 taxa were in the sample including C. multifilis at 71/mL and S. setigera at 20/mL
(Table: 6/6/2005-Site 1). Other taxa found in both years were Closterium acutum (15/mL-1997;
20/mL-2005), Coelastrum microporum (15/mL-1997; 10/mL-2005), Dictyosphaerium
pulchellum (15/mL-1997; 10/mL-2005) and Scenedesmus abundans (30/mL-1997; 10/mL-2005).
None of the taxa seen in 2005 was numerous. The Site 4 sample taken on 6 June, 2005
contained 15 taxa (Table: 6/6/2005-Site 4). K. lunaris var. lunaris in a density of 122/mL was
the only one that was numerous. None of the 10 taxa observed in the Site 5 sample from that
date was numerous (Table: 6/6/2005-Site 5). Only three taxa were common to the three sites
sampled in 2005. They were A. falcatus var. acicularis (10/mL-Site 1; 82/mL-Site 4; 31/mL-Site
5), Oocystis borgei (10/mL-Site 1; 20/mL-sites 4 and 5) and S. abundans (10/mL-sites 1; 4;
31/mL-Site 5). None of the five species seen in the sample taken on 30 July, 1997 was
numerous. The same was true for the 12 taxa observed at Site 1 and Site 5 or the 17 found at
Site 4 on 25 July, 2005 (Tables: 7/25/2005-Site 1; 4; 5). Two taxa were common to all four
samples. They were O. borgei (89/mL-1997; 20/mL-Site 1; 61/mL-Site 4; 41/mL-Site 5) and
Tetraedron minimum (15/mL-1997; 31/mL-Site 1; 82/mL-Site 4; 51/mL-Site 5). A. falcatus var.
acicularis (10/mL-sites 1 and 5; 71/mL-Site 4) was the only taxon common to the three sites
sampled in 2005. A. falcatus var. acicularis was the only taxon of five in a density >100/mL in
