Notes:
Population estimate (derived from redd counts, complete census except for Bear Valley Creek) provided by California Department of Fish and Wildlife. Zeros represent no spawners detected. Data are preliminary and subject to change.
 
This value assumes two spawners per redd. The relationship between estimates of redd abundance and escapement has not been statistically established for this watershed. The entire Lagunitas Creek watershed (including the tributaries of Olema Creek, San Geronimo Creek and its tribs, Devils Gulch, and Cheda Creek, but excluding Bear Valley Creek) was surveyed for adult spawners and redds. 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 NMFS recovery target for Chinook salmon for Lagunitas Creek, as it is south of the currently accepted range of the California Coast Chinook Evolutionary Significant Unit (ESU) (NMFS 2005).
 

Coho salmon are federally listed as endangered. Chinook and 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.
