Delta Science Plan (2016 update)

The Delta of the Sacramento and San Joaquin rivers is the hub of California’s extensive water supply system and critical to the State’s economy. However, emerging scarcities of water in the Delta watersheds, which are expected to intensify with global warming, threaten California’s ability to sustain further economic development and population growth.  At the same time, patterns of water and land use have resulted in severe declines in the abundances of many valuable native species. Protecting and restoring these species while maintaining a reliable water supply and building California’s economic future is an absolute priority.

The economic and environmental stakes in the Delta are enormous. Over 27 million people rely on Delta water and the ecosystem has been degraded to the point where over 60 native species are listed as threatened or endangered. The Delta and its water supply infrastructure are also highly vulnerable to earthquakes, floods, and droughts. Proposed actions under the Bay Delta Conservation Plan to reduce risks to the people, ecosystems and economy of California are likely to cost many billions of dollars. Achieving the co-goals of the Delta Plan will depend upon acquiring and communicating a new shared body of scientific knowledge to catalyze cultural change. The Delta Science Plan is intended to be that catalyst.

The Delta Science Plan provides direction for achieving an integrated, collaborative and transparent science of the Delta to enhance policy and management decisions. The Plan is transformative and uses principles that have proven successful in other Big Science programs – embracing emerging technologies and fostering open science communities. The science plan uses collaboration to build trust and acquire a shared body of scientific knowledge. It proposes new mechanisms for synthesis and communication that will enhance decision-making and reduce conflicts that hinder policy decisions. Vigorous and sustained investment in the Delta Science Plan will ensure that the responsible agencies have the knowledge, trust and collaboration necessary to achieve the coequal goals.
