Notes:

Population estimate (direct count video weir and mark/recapture) for coho and Chinook. Adult steelhead count only. Monitoring period: Chinook and coho season. Monitoring ended prior to end of steelhead migration. This represents a minimum count. Data provided by California Department of Fish and Wildlife. Data are preliminary and subject to change.

Coho salmon in the Scott River basin are state and 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 salmon and steelhead populations in the Scott River basin not considered at risk of extinction by NMFS. No target defined.

The 2016/17 snapshot is defined as fall 2016 to spring 2017, as per when salmon and steelhead return from the ocean to spawn. Fall Chinook spawning season is fall 2016. Coho season is fall through early January 2017. Steelhead season can start in fall 2016 but is primarily winter and spring 2017.
