The 24-page Layperson’s Guide to the Delta explores the competing uses and demands on California’s Sacramento-San Joaquin Delta. The 11th edition examines this critical water hub and its myriad challenges. The 2025 version includes the latest information on the tunnel project, habitat restoration efforts, climate change impacts and an updated section on the legal and political facets of the Delta.

Included in the guide are the history of the Delta, its role in the state’s water system, and its many complex issues with sections on water quality, levees, salinity, invasive species, fish and wildlife and water distribution. New sections focus on the ongoing efforts to protect water quality and restoring a faltering ecosystem while maintaining the Delta’s role as the nucleus of the state’s water supply. A glossary of common terms and a roster of the many state and federal agencies involved in Delta issues are also included.

Complementing the guide is the Sacramento-San Joaquin Delta Map.
