We continued to investigate two population viability metrics of salmonids in the Smith River basin (California and Oregon), with ESA listed coho salmon (Oncorhynchus kisutch) as the focal species. First, we monitored adult salmonid escapement and distribution for a fourth year during the winter of 2014-2015 using a combination of live fish, carcass, and redd counts as defined in California’s Coastal Salmonid Monitoring Plan. The spawner survey sample frame includes 161.8 kilometers of potential spawning habitat divided into 68 reaches and 30 sub-reaches. We completed 414 spawning ground surveys in 30 main reaches and 11 sub-reaches throughout the Smith River basin during the 2014-2015 season.
