Description

The purpose of this project is to continue the 20 year monitoring data set of Chinook Salmon, Coho Salmon and steelhead adult and smolt population abundances and life stage survival rates at the Freshwater Creek Lifecycle Monitoring Station, Humboldt County. Abundance estimates are made for multiple life history stages, at multiple spatial scales for Coho Salmon, Chinook Salmon, and steelhead trout. Several methods were used to characterize abundance including: 2021-22 Adult escapement: weir-carcass mark-recapture experiment, 2021-22 Spawning ground surveys, and 2022 Juvenile emigration trapping mark-recapture experiment. Survival estimates were made using mark-recapture experiments: 2020 Smolt to Adult Return (SAR) survival and 2022 Coho Salmon pre-spring and spring migrant probability estimates.

Project Benefit

Freshwater Creek will be represented in coastal Coho Salmon stock assessments of the region. This project will collect data for the adult abundance and juvenile components of the LCM to continue these time series and allow for assessment of coastal Coho Salmon trends in escapement and productivity over nearly 180 km of California coast north from the Eel River to the Oregon border.
