shown in tables 16-23. Distribution pat- 

 terns were different for each species; some 

 species showed definite patterns of distri- 

 bution based on stream sizes, whereas 



others occurred seemingly with no rela- 

 tion to stream sizes. 



As might be expected in a group of 

 streams that differed from each other in 



Table 16. — Suckers. Average numbers of each of several species taken in the 1959 survey 

 (quantitative samples only) in streams of various size ranges. Each species average is for only 

 those stream systems in which the species occurred in the quantitative collections.
