Notes:

Population estimate (derived from redd counts) provided by California Department of Fish and Wildlife. The California Coastal Salmonid Monitoring Program for Gazos Creek initiated in 2011/12. Zeros represent no spawners detected. Due to persistent high flows from mid-Devember through the end of March, only a few surveys per reach were done throughout the spawning period. No population surveys were conducted by CDFW due to lack of funding

Coho salmon are federally listed as endangered. Steelhead 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 2012, NMFS 2016).

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. Spring Chinook return in spring 2016 and spawn in the fall 2016.
