The goal of this research is to better understand how climate change will affect fishes with different life histories and habitat associations across the San Francisco Estuary. Existing datasets will be incorporated in synthetic analyses and cutting-edge statistical models to identify fish community responses to climate, flows, and habitats along the estuarine salinity gradient. This synthesis-science project will use rich long-term datasets that have been collected by Bay-Delta researchers for decades that will then be analyzed in a reproducible and open science framework. It will also support efforts by the Interagency Ecological Program’s Climate Change Project Work Team.
Managing California’s water supply is complex, requiring careful coordination to ensure sustainability, water quality, and the protection of public and environmental health. In the Sacramento–San Joaquin Bay-Delta, hundreds of datasets from studies and monitoring programs are used to assess conditions and inform key operational decisions. However, these datasets are often fragmented across agencies and stored in inconsistent formats, making it time-consuming for analysts and researchers to locate and use the data effectively.
This project aims to enhance the Bay-Delta Live (BDL) data management platform (www.baydeltalive.com) by integrating datasets from the California Department of Water Resources’ Water Data Library (WDL). The primary focus is on water quality and environmental monitoring data. By streamlining access to these resources, the project will improve the discovery, retrieval, and analysis of water-related datasets across multiple sources.
Key outcomes include:
This work will support more informed decision-making and help ensure the long-term safety, reliability, and ecological integrity of California’s water resources.
The foundation of conserving a species is monitoring its abundance and habitat. This proposed work has three objectives which will help monitor green sturgeon abundance and understand green sturgeon habitat selection. These objectives build on 12 years of work to support the recovery of green sturgeon. The first objective is to continue the annual green sturgeon spawner census, while also improving our methods. This census is the main piece of information used in monitoring and assessing the Delta resident green sturgeon population. The second objective is to assess spawner site selection and habitat use which will help better understand sturgeon environmental needs so that restoration can better target those needs. The third objective is to assess the relationship between spring flow rates, temperature, and number of spawners observed, which will help managers better understand sturgeon flow cues and improve the accuracy of our spawner census.
