The Situk River is among the most productive resource in Alaska, with nine native fish species and 10 times the density of juvenile coho salmon than any other Southeast Alaskan watershed. The associated fisheries in the Situk River and its adjoining estuary drive a $2 million economy for the community of Yakutat (population 600), with 89 percent of the households harvesting salmon for subsistence purposes. The Yakutat foreland area that encompasses the Situk River watershed is a vast landscape of low gradient drainages with forested mosaics of side channels and pools that are responsible for up to 80 percent of coho salmon production. These highly productive aquatic habitats are sensitive to even small shifts in...

Assessments that incorporate areas from land-to-ocean, or “ridge-to-reef", are critical to examine how land-use practices are altering stream discharge and nearshore marine health and productivity. Stream systems in both Alaska and Hawaiʻi are expected to experience changes in water quality associated with changing environmental conditions and increased human-use. Watershed systems throughout the Hawaiian Islands are currently experiencing impacts from climate change that affect groundwater recharge and surface runoff, erosion, and total streamflow, and cause degradation of nearshore marine habitats. This study can provide useful insight for both Alaska and Hawaiʻi by providing resources on how patterns in stream...
