Public webinar on AB 1755 implementation

The State agencies implementing AB 1755, the Open and Transparent Water Data Act, hosted a public webinar on Thursday, March 29. A recording of the webinar is available.

What is the Open and Transparent Data Act?

The Open and Transparent Water Data Act (AB 1755, Dodd) requires the Department of Water Resources, in consultation with the California Water Quality Monitoring Council, the State Water Resources Control Board, and the California Department of Fish and Wildlife, to create, operate, and maintain a statewide integrated water data platform; and to develop protocols for data sharing, documentation, quality control, public access, and promotion of open-source platforms and decision support tools related to water data.

  • January 1, 2018 – protocols and strategic plan to guide program implementation
  • September 1, 2019 – operational integrated water data platform with available water and ecological/fisheries state agency datasets
  • August 1, 2020 – available water and ecological/fisheries data related to California water supply and management held by identified federal agencies

DWR and partner agencies are collaborating with and learning from other State and federal agencies, data experts, and AB 1755 stakeholders, including data providers and consumers to chart a successful path forward.

Why is an open data platform important?

  • Integration of existing water and ecological/fisheries data will: support analysis across datasets and disciplines; help water managers operate more efficiently; and help water users make informed decisions based on water availability and allocation;
  • State agencies should promote openness and interoperability of water data;
  • Increased transparency of public data is good government;
  • Water data and information technology tools and applications developed and gathered using state funds should be made publicly accessible and open-source, whenever possible;
  • Increased access to data will support better-informed decisions and cost-effective investments;
  • AB 1755 will support greater use of data collected and increase awareness of the importance of data in water management;
  • Making information accessible, discoverable, and usable by the public can foster entrepreneurship, innovation, and scientific discovery;
  • More comprehensive and interoperable datasets will provide unique opportunities to develop data-search and data-packaging products and services
