AB 1755: Open and Transparent Water Data Platform for California

What is the Open and Transparent Data Act?

The Open and Transparent Water Data Act (AB 1755, Dodd) requires DWR, 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;
  • develop protocols for:
    • data sharing
    • documentation
    • quality control
    • public access
    • promotion of open-source platforms
    • promotion of decision support tools related to water data

A team of partner agencies is collaborating with and learning from others – including State and federal agencies, data experts, data providers, and data consumers – to chart a successful path forward.

Why is open data 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.
  • 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 supports better-informed decisions and cost-effective investments.
  • 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.
