diatom report contains an alphabetical list of diatom species and their percent abundances, and 

 values for 65 different diatom metrics and ecological attributes. 



Field Notes (R. Ridenour) 



Dog Creek. In decreasing order of importance, rock, sediment, and higher plants were 

 the most common substrates at this site. Macroalgae covered about 10% of the substrate area 

 and the remaining 90% appeared to be bare of algal growth. 



Eagle Creek. In decreasing order of importance, rock, wood, sediment, and filamentous 

 algae and macrophytes were substrates for algal growth at the upper site. Macrophytes covered 

 20% of the substrate area, macroalgae 10%, and mosses 1%. All plants appeared to be healthy 

 and growing to mature. At the middle site, rock, sediment, and macrophytes/filamentous algae 

 were the most important algal substrates, followed by wood. Forty percent of the substrate area 

 was covered by microalgae and 40% was covered by macrophytes. Plants were growing to 

 mature. Rock, sediment, and filamentous macroalgae were the most important substrates at the 

 lower site. Here macroalgae and macrophytes each covered about 20% of available substrates 

 and appeared to be mature or senescent. Moss was also present, covering about 1% of the area. 



Sample Notes 



Dog Creek. The sample from Dog Creek was silty and contained plant stems and leaves. 



Eagle Creek. The sample from the upper site on Eagle Creek was packed full of 

 filamentous algae. The sample collected from below Highway 236 was silty and contained 

 macrophytes. The sample from the lower site on Eagle Creek had about three-quarters of an inch 

 of sediment on the bottom of the container. Chara was the only visible alga in this sample.
