High school students in Northern California are helping real scientists study a mystery that’s killing baby salmon – and they’re doing it right from their classrooms.

The Institute of the Environment's Earth and Environmental Justice Scholars cohort for the 2025-2026 academic year has been announced!

"A vitamin deficiency likely killed as many as half of newly hatched fry of endangered winter-run Chinook salmon in the Sacramento River in 2020 and 2021. These new findings were published in the Proceedings of the National Academy of Sciences [led by CWS Senior Researcher Rachel Johnson].

In this episode of the Fish Water People Podcast, Michael Rogner, Associate Director of Restoration Science at River Partners, discusses large-scale riparian habitat restoration in California's Central Valley. Rogner explains how his organization transforms former agricultural lands into native habitats, focusing on restoring the Sacramento River's ecosystem. By converting fallow fields into native landscapes, River Partners has restored 20,000 acres, creating multiple benefits including flood control, groundwater recharge, wildlife habitat, and community access to green spaces.

The UC Davis Center for Watershed Sciences (CWS) was recently featured in a CBS News Bay Area segment about the research being conducted on salmon ear bones - known as otoliths - and about the restoration efforts that brought the salmon back to Putah Creek.

We’re excited to announce the appointment of Karrigan Börk as the Director of the UC Davis Center for Watershed Sciences (CWS). Börk is a Professor of Law and Co-Director of the California Environmental Law and Policy Center, who has served as interim Director of the Center for Watershed Sciences since 2024.

The Winnemem Wintu tribe’s connection to the winter-run chinook salmon (known as Nur by the tribe) runs deep. The Nur are a part of the creation stories told for generations.

“When we first bubbled out of our sacred spring on Mt. Shasta at the time of creation, we were helpless and unable to speak. It was salmon, the Nur, who took pity on us humans and gave us their voice. In return, we promised to always speak for them.” – Winnemem Wintu Spiritual and Cultural Belief.
