2022 Water Data Challenge Themes: 

Racial Equity | Policies and Regulations | Data Accessibility | Data Quality

California is implementing the Open and Transparent Water Data Act to publish water and ecosystem information in an open data format. In addition to fostering the development of innovative tools and insights related to safe drinking water, the California Water Data Challenge will provide participants an opportunity to engage with the open data portal and submit feedback, advice, and suggestions for consideration as this effort is being implemented.


Data has the power to help us see challenges through different lenses, discover solutions that may not otherwise be evident, and put tools into the hands of those who need them most — empowering the community to work together in new ways. The 2022 Water Data Challenge focuses on open data to collectively assess what we know and prepare for a more resilient future. 


Submit your open data project through Dec. 16, 2022 to be eligible for non-cash prizes toward education and professional development awards! Read more about the Challenge Questions at https://waterchallenge.data.ca.gov/the-challenge/

Questions Answered

What data should I use for the Challenge?

In support of the Open and Transparent Water Data Act (AB 1755), teams are encouraged to explore the many Open Data resources available on the Challenge Data and Resources Page.

At least one open data resource must be used to be considered for awards, and if any restricted-access data are leveraged for a project, teams should provide details to enable submission review and community engagement.

How large are the project teams?

While we don't restrict team sizes, and encourage collaboration broadly, typically projects are co-designed, developed, and submitted by a core team of 2-6 people. Individuals are welcome to submit projects as well.

During the submission process, you will be asked to list the core project contributors to facilitate distribution of any awards. Beyond the core team members submitting the project, acknowledgements of mentors, collaborators, advisors, and resources used for a project are welcome.

We use Submittable to accept and review our submissions.
