TAXONOMIC COVERAGE:
Organisms studied

Methods:	Water samples for sestonic chlorophyll were collected weekly. Epilithic chlorophyll was sampled on rocks in riffles early, mid, and late summer. A plastic 35mm slide mount was used to partition a known area from which the algae was scraped from the rock surface with a brass brush. The brushed area of the rock, the brush and slide holder were then rinsed and the slurry collected and brought up to a volume of 56 ml. Five rocks were sampled from each riffle station The samples were returned to the lab, homogenized for 10s in a blender, and filtered through a GF/C glass fiber filter. The filters were then placed in 10 ml of 90% acetone and extracted in the dark for 24 hours. The samples were then read on a Turner 450 Fluorometer. Reference Citations: R.G. Wetzel & G.E.
