The purpose of this project is to expand the existing San Francisco Bay Regional Data Center (RDC) to include the Sacramento-San Joaquin Delta and Suisun Marsh (Delta). The anticipated outcome of this project is an estuary-wide data repository where one currently does not exist. The goals are to work with data providers collecting data in the Delta, harmonize data for improved interoperability, and increase access to, and exchange of, high-quality environmental data from public and private sector sources for scientists, environmental program staff, managers, the public and other stakeholders. The project phases include convening engaged workgroups and stakeholders to help set priorities for data collection, and prioritizing datasets that address water quality pollution in the Delta ecosystem and focus on nutrient enrichment and toxic contaminants in priority habitat restoration areas.

By contributing the collected data to the California Environmental Data Exchange Network (CEDEN) and in turn EPA’s Water Quality Exchange (WQX), the Bay-Delta Regional Data Center (RDC) will ensure broad dissemination of data to support the state’s mandated reforms to the Delta’s water resources and ecological management. An effort of the Delta Watershed Initiative Network (DWIN), this estuary-wide data repository presents an opportunity to provide accessible and synthesized data for scientists and decision-makers for comprehensive policy solutions and effective management. This project will leverage previous investments made to standardize and manage water quality data, and align resource-management and regulatory needs.
