Sample observations and analyses of soft (non-diatom) algae 

 were recorded in a lab notebook along with station and sample 

 information provided by MDEQ . A portion of the raw sample was 

 used to make duplicate diatom slides. After completing the 

 diatom proportional count, the slide used for the count will be 

 deposited in the University of Montana Herbarium in Missoula. 

 The other slide will be retained by Hannaea in Helena. 



On completion of the project, station information, sample 

 information, and diatom proportional count data will be entered 

 into the Montana Diatom Database. 



RESULTS AND DISCUSSION 



Results are presented in Tables 5 and 6, which are located 

 near the end of this report following the Literature Cited 

 section. Spreadsheets containing completed diatom proportional 

 counts, with species' pollution tolerance classes (PTC) and 

 percent abundances, are attached as Appendix A. 



SAMPLE NOTES 



Antelope Creek. At least two species of Spirogyra were 

 present in this sample. 



Potter Creek. Most of this sample was composed of vascular 

 plant stems and leaves. The Cladophora in this sample was 

 senescent and covered with epiphytes,- Oedogonium, Protoderma, 

 Stigeoclonium, and Phormidium were present only as epiphytes on 

 Cladophora. 



NON- DIATOM ALGAE 



Green algae and chrysophycean algae, including diatoms, were 

 present in both Antelope Creek and Potter Creek, and blue-green 

 algae were present in Potter Creek but noticeably absent from
