What We Have  
What We Need  

Estimates are based on DIDSON/redd surveys. Stream had insufficient flows for majority of the year. Passage flows began March 1 and lasted only about three days, well past the peak migration period.  Data provided by California Department of Fish and Wildlife. Data provided by California Department of Fish and Wildlife. Zeros represent no spawners detected. Data are preliminary and subject to change.

Steelhead are currently federally listed as endangered. Spawning adult fish recovery targets represent the biological conditions National Marine Fisheries Service would use to delist the species and remove them from the Federal List of Endangered and Threatened Wildlife and Plants (50 CFR 223.102). Current target is not specific to Topanga Canyon Creek but to Southern California Coast Steelhead Recovery Area populations. As quantitative field data becomes available, specific targets may be defined (NMFS, 2012). 

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.
