Chandalar River chum salmon (Oncorhynchus keta) riverscape-scale salmon habitat assessment and monitoring

Duration

January 2015 - December 2016

Narrative

An increase in mining exploration and the effects of climate change have raised concerns about the future of Chandalar River chum salmon among local community members and state and Federal fisheries managers. Yukon fall chum rely on systems that are spring fed or have geologically significant hyporheic groundwater upwellings, since these locations provide stable water temperatures for eggs and juveniles throughout the winter months. However, limited information is available on the spatial distribution and frequency of these upwellings on the Chandalar River. The goals of this project are to identify the longitudinal patterns of groundwater upwellings, as measured by thermal variability, and the relationship between the spatial distribution of spawning salmon and groundwater discharge patterns. This project is funded by U.S. Fish and Wildlife Service Subsistence Management Program.
