Preservation: no preservative

Notes: The algae appeared alive and healthy.

Result: The dominant taxon was the filamentous blue-green alga Scytonema sp., 

which belongs to Class Cyanophyceae.

Other algae present in the sample included the filamentous yellow-green 

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

Microspora sp.

Preservation: Lugol’s

Notes: 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.

Notes: The algae appeared alive and healthy, except for Cladophora 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 

filaments of Cladophora appeared alive and green in color at the tips but 

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

present.

Notes: The phytoplankton in the sample appeared alive and healthy.

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 processed and results will be 

forthcoming. Relative proportions could change with longer settling times.

Notes: The algae appeared alive and healthy.

Result: The dominant taxon was the filamentous yellow-green algaVaucheria sp., 

which belongs to Class Xanthophyceae.

Other algae present in the sample included the filamentous blue-greens 

Scytonema sp., Microchaete sp., and Planktolyngbya sp. as well as the 

filamentous green alga Hydrodictyon reticulatum, commonly known as 

water net. The diatom Epithemia sp. was attached to the filaments of 

Vaucheria sp. and Scytonema sp.

Notes: The phytoplankton in the sample appeared alive and healthy.

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

examination indicates the presence of Anabaena circinalis and Dinobryon 

seritularia 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.

Notes: The phytoplankton in the sample appeared alive and healthy.

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 

times.
