Notes:

Fish counts (infrared scanner at Freeman Diversion Dam) provided by United Water Conservation District. Total resident population (i.e., non-ocean going) has not been estimated but is presumably much larger (NMFS 2011). Data are preliminary and subject to change.

Steelhead are federally listed as endangered. 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). Current target is not specific to the Santa Clara River but to Southern California Coast Steelhead Recovery Area populations. As quantitative field data becomes available, specific targets may be defined (NMFS 2012).

The 2014/15 snapshot is defined as fall 2014 to spring 2015, as per when salmon and steelhead return from the ocean to spawn. Fall Chinook spawning season is fall 2014. Coho season is fall through early January 2015. Steelhead season can start in fall 2014 but is primarily winter and spring 2015. Spring Chinook season is spring 2015.
