Anabaena was not abundant enough in Big Dry Creek to pose a 

 problem for livestock producers. 



Little Dry Creek 



The sample from Little Dry Creek also contained a mix of 

 green algae, diatoms, euglenoid algae, and cyanobacteria . Only 

 five genera of non-diatom algae were present . 



Diatoms dominated the sample from Little Dry Creek, followed 

 by green algae, cyanobacteria, and euglenoids . Euglena, a good 

 indicator of organic loading, was rare at this site. 



Big Dry Creek and Little Dry Creek had only three genera of 

 non-diatom algae in common: Oedogonium, Euglena, and Phormidium. 

 The absence of Anahaena and the abundance of the filamentous 

 green alga Rhizoclonium indicates that Little Dry Creek probably 

 had cooler water and more water movement than did Big Dry Creek. 

 It should also be noted that the sample from Little Dry Creek was 

 collected in the Spring, when higher flows and cooler waters are 

 to be expected. The sample from Big Dry Creek was collected in 

 late Summer of a particularly dry year (2000) . 



DIATOMS 



Big Dry Creek 



The major diatom species in Big Dry Creek were all somewhat 

 tolerant to very tolerant of nutrient enrichment, organic 

 loading, and elevated dissolved solids (Table 5) . 



The dominant diatom in Big Dry Creek was Navicula 

 duerrenhergiana. This diatom has been reported mainly from 

 / brackish seas and coastal waters in Europe and Israel (Kraramer
