California is facing the most serious water crisis in its history, because of the combined effects of drought, increasingly‐stringent environmental protections on water project operations, inadequate infrastructure and the failure to protect the reliability of existing water supplies. The state’s water system was designed and constructed by far‐sighted leaders during the 20th century and provided valuable services to a growing economy for a half century or more. But today, circumstances are changing significantly and that magnificent system is failing with adverse effects for both California’s economy and environment. In fact, there has been a substantial reduction of available water supplies conveyed across the Delta. The Association of California Water Agencies (ACWA) has released several comprehensive water policy documents to help outline the critical needs of California Water.
