California Open Water Data Atlas
In 2016 California passed the Open and Transparent Water Data Act (AB 1755), promising one integrated, open platform for the state's water and ecological data. This atlas maps the decade since: what the law required, what the 2018 Strategic Plan set out to do, and where things stand today.
The Law
AB 1755's requirements, the data it names, and four statutory deadlines.
The Plan
The April 2018 Strategic Plan: 4 goals, 11 objectives, 49 dated actions, and a bet on federation.
Timeline
2016–2026: platforms, the Water Data Consortium, progress reports, funding.
Scorecard
All 49 strategic actions graded against public evidence: 9 done, 20 partial, 17 with no public record.
Ecosystem
Agencies, portals and partners that make up California's water-data federation.
Today
Current status against the statute, and what comes next.
Dashboard
Every published water dataset on both portals by year, topic, publisher and page views, plus how consistently the two portals federate.
