Surface Storage Investigations


Water resources planning has changed significantly over the past several decades. New approaches to planning for CALFED surface storage has resulted in a new era of project formulations designed to address new water resources needs in California. The State and federal governments have funded the five Surface Storage Investigations, which were explicitly conceived to support at least three of CALFED's programmatic goals: water supply reliability, water quality, and ecosystem restoration.

These new projects are being designed to be adaptive and robust, and would support aquatic and riparian ecosystem restoration focused on the Delta and its tributaries, improved drinking and habitat water quality, and the water supply needs associated with California's growing population and diverse economy. Furthermore, these projects must perform well under a number of potential future conditions including changing environmental conditions and needs, climate change, alternative Delta conveyance and management, and disaster/emergency response scenarios.
