Notes:

Population estimates based in mark/recapture and redd counts for fall Chinook and summer dive surveys for spring Chinook and summer steelhead provided by California Department of Fish and Wildlife and the Salmon River Restoration Council. Incomplete estimates for coho salmon and winter steelhead because monitoring ended prior to the end of coho salmon and winter steelhead migration. Turbidity on NF Salmon may underestimate fish numbers for spring-run Chinook. Data are preliminary and subject to change.

Coho salmon are federally listed as threatened. The “What We Need” spawner population abundance targets shown above represent just one of several criteria that the National Marine Fisheries Service considers when determining whether a species should be removed from the Federal List of Endangered and Threatened Wildlife and Plants (50 CFR 223.102). Recovering any of the species entails meeting criteria for abundance, productivity, diversity, and spatial structure across multiple watersheds, as well as criteria for alleviating threats (NMFS 2014).

* Chinook and steelhead in Salmon River are not considered at risk of extinction. No target defined.

The 2015/16 snapshot is defined as fall 2015 to spring 2016, as per when salmon and steelhead return from the ocean to spawn. Fall Chinook spawning season is fall 2015. Coho season is fall through early January 2016. Steelhead season can start in fall 2015 but is primarily winter and spring 2016. Spring Chinook return in spring 2015 and spawn in the fall 2015.
