From the Delta Science Program:
The Delta Stewardship Council’s Delta Science Program is developing the third iteration of the Delta Science Plan, which outlines the vision, principles, and approaches that guide science in the Sacramento-San Joaquin Delta. Updated approximately every five years, the plan incorporates new concepts and actions that reflect current science and management needs and is developed collaboratively and transparently.
The draft 2026 Delta Science Plan is available for public review! All members of the Delta science community and interested parties are invited to provide input, including federal, state, and local agency scientists, tribes, non-governmental organizations, academic researchers, and interested members of the public.
The comment period opened on November 19, 2025, and the closing date has been extended to January 30, 2026. Comments may be submitted through this online survey (estimated to take 30 minutes), emailed to collaborativescience@deltacouncil.ca.gov, or mailed to the following address to be considered.
