California Department of Water Resources

DWR manages California's water resources, systems, and infrastructure, including the State Water Project (SWP), in a responsible, sustainable way.

Dutch Slough Habitat Restoration Study

This project studies how fish have colonized newly created tidal wetlands at Dutch Slough while also examining carbon flux and bird usage in the restored habitat.

Suisun Marsh Fish Study

This project monitors fish and invertebrate populations in Suisun Marsh to track trends in sensitive and native species, guide water management decisions, and provide a long-term baseline for research on wetland health and restoration.

Origin and Abundance of Chinook Salmon in Putah Creek

This project monitors Chinook salmon abundance, reproduction, and migration in Putah Creek through carcass surveys, juvenile trapping, acoustic tagging, and ecological studies, supporting science-based conservation and serving as a training ground for future fisheries and watershed professionals.

Tracking Critical Habitats with Isotope Diaries in Fish

This project uses chemical markers in salmon otoliths and eye lenses to reconstruct detailed, time-resolved habitat histories and quantify the role of key environments, particularly floodplains, in the survival of endangered and natural-origin Chinook salmon in the Sacramento River.

California Salmon Thiamine Deficiency Research and Mitigation

This project investigates thiamine deficiency in California Chinook and coho salmon, linking dietary shifts toward northern anchovies to reproductive failure and neurological dysfunction, while developing monitoring and mitigation strategies to protect endangered populations.

Agricultural Production, Water Use and Employment

This program quantifies agricultural production, land use, water use, economic value and employment using optimization approaches such as the SWAP model (http://SWAP.ucdavis.edu) and statistical information.

Satellite Remote Sensing and Consumptive Water Use in the Delta

This study for the state Delta Protection Commission compared the effectiveness of using new remotely sensed measurement technology to estimate farmers' "consumptive water use," or the amount of irrigation water crops transpire and evaporate from the nearby soil.
