N otes: The a lgae appeared alive and healthy.

Result: The dominant taxon was the filamentous blue

- green alga Scytonema sp.,

which belongs to Class Cyanophyceae

. Other alga e present in the sample included the filamentous yellow

- green alga Vaucheria sp. and two filamentous green genera, Oedogonium sp., and

Microspora sp.

N otes: The phytoplankton in the sample appeared alive and healthy.

Result: Bloom conditions were not apparent from the water column sample. A

preliminary examination indicates the presence of Trachelomonas sp. and

Cryptomonas sp. in a greater proportion relative to other algae however, a

sample for full identification and enumeration is being processed and

results will be forthcoming. Relative proportions could change with longer

settling times.

N otes: The a lgae appeared alive and healthy , except for Clad o phora sp.

Result: The dominant taxon was the filamentous green alga Spirogyra sp., which

belongs to Family Zygnemataceae

. Other algae present in the sample included the filamentous blue

- green alga

Calothrix sp. growing on filaments of the green alga Cladophora sp. The

f ilaments of Cladophora appeared al ive and green in color at the tips but

dying at the base. The filamentous green alga Oedogonium sp. was also

present.

Result: Bloom conditions were not apparent from this sample. A preliminary

examination indicates the presence of Spirogyra sp. and Anabaena sp. in a

greater proportion relative to other algae however, a sample for full

identification and enumeration is being proc essed and results will be

Result: Bloom conditions were not apparent from this sample. A preliminary

examination indicates the presence of very few Anabaena sp. (not A.

circinalis ) in a greater proportion relative to other algae however, a sample

for full identification and enumeration is being processed and results will

be forthcoming. Relative proportions could change with longer settling
