DELTA CONVEYANCE PROJECT: Securing statewide water supplies part 7: System flexibility means reliable water supplies

From the Department of Water Resources:

Every water year is unique, with some being dry and others wet. California’s climate has always been highly variable, and as the climate changes, precipitation patterns are becoming even more unpredictable, wildly swinging from extreme drought to intense precipitation and flooding.

Adding a new point of diversion with the Delta Conveyance Project creates flexibility to adapt to our changing climate while continuing to protect fish and water quality in the Delta, allowing the state to maximize the amount of water captured from high flows and stored for later use.

Four years of data show the Delta Conveyance Project will provide critical water supply benefits regardless of the water year type by adding system flexibility to improve water management and adapt to changing weather patterns and sea level rise.
