Elk Creek. Algae were sparse in the sample from Reach 1 3 and the sample contained 

 some silt and a little moss. Algae were also sparse in the sample from Reach 3 and the sample 

 was a bit more silty. 



Jim Creek. The sample from Jim Creek Reach 5 contained mostly moss. 



Piper Creek. The sample from Reach 14 was silty. Moss was present and diatoms were 

 sparse. Diatoms were also sparse in the sample from Reach 2. 



Non-Diatom Algae 



Goat Creek. Diatoms and cyanobacteria dominated the benthic algal flora of Goat Creek 

 (Table 3). Schizothrix, a filamentous cyanophyte that forms rubbery crusts on rocks, was 

 particularly abundant here. The pollution-sensitive filamentous red alga Audouinella was also 

 common in Goat Creek. Green algae were not abundant and appeared only at the two lower 

 stations. 



Elk Creek. The tufted filamentous cyanophyte Amphithrix was the most common alga at 

 the upper site on Elk Creek (Table 3). Audouinella ranked second in biovolume at this site. The 

 semi-aquatic green alga Protoderma was the most common alga at the lower station. Diatoms 

 were sparse in Elk Creek. 



Jim Creek. The filamentous cyanophyte Oscillatoria was the most abundant alga in Jim 

 Creek Reach 5 (Table 3). This genus contains many species, some of which are tolerant of 

 organic pollufion. Diatoms ranked second in biovolume in Jim Creek, which also supported the 

 filamentous green alga Ulothrix and the filamentous xanthophyte Tribonema. 



Piper Creek. This stream supported a mix of diatoms, red algae, green algae, and 

 cyanobacteria (Table 3). Audouinella was most abundant at the upstream site and Oscillatoria 

 was most abundant at the downstream site. Diatoms were common here.
