Monitoring O. mykiss Life Stages on the Stanislaus River 2021-2025

This study is designed to partly address steelhead conservation measures outlined in the U.S. Bureau of Reclamation's Proposed Action for the Long-Term Operation of the CVP. This effort is funded under the Central Valley Project Improvement Act (CVPIA) authority Provision 3046 (g)(4), which states the primary purpose of this effort shall be to support the Secretary's efforts in fulfilling the requirements of this title through improved scientific understanding concerning, but not limited to, measures needed to restore anadromous fisheries to optimum and sustainable levels in accordance with the restored carrying capacities of Central Valley rivers, streams, and riparian habitats.
Conceptual and quantitative work described in this report encompass multiple O. mykiss
life-stages and transitions among life stages. The geographic scope of the report includes the Lower Stanislaus River, extending from Goodwin Dam down to the confluence of the San Joaquin River.
The goal of this study is to develop a framework for monitoring life stages, and transitions among life stages, to quantify how water project operations and environmental variation influence life history expression, abundance, and population productivity.
Data is recorded in a combination of paper to computer files and electronic-only files. Annual reports summarize the survey findings. While this project is ongoing, this is a completed dataset for the collection sessions performed in the years 2021- 2025.
