“…Coho salmon, Dolly Varden, and steelhead were captured in reaches with gradients above 15% and were generally captured in small step pools. The densities of Dolly Varden and coho salmon fry and parr that we observed were lower than those reported for lower-gradient streams in southeast Alaska (Dolloff 1983;Bryant et al 1991). We did not observe coho salmon spawning in the high-gradient streams of our study, which may contribute to the lower densities of coho fry and parr that we observed.…”

We evaluated the species distribution, abundance, and habitat relationships of salmonids in small first‐ to second‐order headwater streams in southeast Alaska. Streams were separated into three zones based on gradient and sampled during the spring, summer, and fall. Dolly Varden Salvelinus malma were found in all streams where fish were present. They were the dominant species in moderate‐ (mean gradient = 5.5%) and high‐gradient (mean gradient = 12.9%) zones. Coho salmon Oncorhynchus kisutch fry and parr were the dominant species in the low‐gradient zone (mean gradient = 3.1%) but were present in higher‐gradient zones. Small numbers of steelhead O. mykiss parr were present in all three zones in the spring and fall. Few were captured during the summer. Coastal cutthroat trout O. clarkii were found primarily in one stream and in all three zones. The density of all species decreased as gradient increased. Anadromous Dolly Varden in spawning condition were observed in the fall up to the highest accessible locations in four streams. Salmonids use high‐gradient reaches when pools are present and accessible. Headwater tributaries comprise a large proportion of most southeast Alaska watersheds, and the combined contribution from all of these tributaries to the fish community may be large. The results from this study underscore the importance of maintaining access for fish throughout watersheds and into small high‐gradient streams.

“…Coho salmon were the dominant species in the low-gradient reaches, and this tends to be common in the small streams of southeast Alaska (Dolloff 1987;Bryant et al 1991). More Dolly Varden than coho salmon were captured in the moderate and high-gradient zones.…”

“…Process-based classification approaches provide additional insights into potential response to disturbance (Schumm, 1977;Paustian et al, 1992;Whiting and Bradley, 1993;Montgomery and Buffington, 1997). Channel type classification may also provide a method to predict abundance of salmonid populations (Bryant et al, 1991). Our study is limited to channels with depositional, rather than erosional or transportational, characteristics (Schumm, 1977).…”

“…Their typical location low in the drainage network makes them likely to integrate cumulative effects of disturbances occurring throughout the watershed. These channel types also support anadromous salmonids that may respond to habitat perturbations (Bryant et al, 1991).…”
