Understanding a Complex Water System in the San Joaquin Valley

This book explains how the western San Joaquin Valley’s groundwater divides into an upper semiconfined zone and a lower confined zone, shaped by ancient clay layers and layered deposits. It traces how irrigation, pumping, and surface water changes have transformed where and how water moves, storage, and is used today.

Readers will learn how different rock and soil layers—Coast Range alluvium, Sierran sands, and flood-basin deposits—affect water flow, storage, and quality. The text also shows how past farming growth created dramatic shifts in water levels, land subsidence, and the need for new irrigation strategies.

• How the Corcoran Clay Member divides the flow system and why that matters for water pressure and movement


• Differences between the Coast Range and Sierran deposits and their impact on permeability


• How agricultural practices and water imports shifted recharge and discharge over time


• Historical maps and observations that document changes in water table and subsidence

Ideal for readers seeking a grounded, data-driven view of groundwater dynamics in a major agricultural region.
