About the Delta Conveyance Project
The Delta Conveyance Project is a proposal to modernize water infrastructure in the Sacramento-San Joaquin Delta by making physical improvements to how we capture and move water during wet years for use in dry years with a tunnel system. The proposed Delta Conveyance Project is intended to restore the reliability of the State Water Project and ensure California’s largest supply of clean and affordable water for 27 million people and 750,000 acres of farmland is protected from earthquakes and climate-driven weather extremes. This page contains information and resources related to various aspects of the proposed project.
