fifteen percent of the sites containing slimy sculpins had stream gradients less than 1 

 percent. Nineteen percent of the sites containing slimy sculpins had stream gradients of 

 1.5%. Another eleven percent of the sites occupied by slimy sculpins had stream gradients 

 of approximately 2%. 



Torrent sculpins were found at sites with stream gradients ranging from less than 1% to 

 1.5%. The majority of sites containing torrent sculpins, sixty-one percent, had a 1% 

 stream gradient. Roughly twenty-two percent of the sites containing torrent sculpins had a 

 1.5% stream gradient. Approximately seventeen percent of the sites containing torrent 

 sculpins were at sites with a stream gradient of less than 1%. 



Shorthead sculpins were evenly distributed at forty-four percent between sites with a 

 1% gradient and sites with a 1.5% gradient. Roughly eleven percent of the sites containing 

 shorthead sculpins had a 2% stream gradient. Shorthead sculpins were not found at sites 

 with a stream gradient less than 1 %. 



Stream Order 



The sampling frequency for each stream order was dictated by the concentration of each 

 stream order in the watershed network as well as seasonal factors. The majority of the 

 sample sites occurred on 3rd and 4th order streams. Most 1st and 2nd order streams were 

 either too small to electroshock or dry during the fall sampling season. In addition, far 

 fewer 5th and 6th order streams exist in the study area, therefore, the number of sample 

 sites for these orders was less than for smaller order streams. 



Sculpins were more likely to be found on 4th, 5th, and 6th order streams than at sites 

 on 2nd and 3rd order streams (Figure 9). There was a greater chance of finding sculpins at 

 a given site as stream order increased.
