AB 2728 (2025-2026) – Open and Transparent Water Data Act
Overview
AB 2728 is a California bill focused on improving access to and transparency of water data. Its core aim is to ensure that water information—covering sources, uses, resources, and related metrics—is collected, managed, and publicly accessible in a clear and timely manner. The bill seeks to enhance accountability, planning, and decision-making by making critical water data more open and usable for policymakers, agencies, researchers, and the public.
Main Purpose and Intent
- To create an open and transparent framework for California water data.
- To standardize the collection, management, and dissemination of water-related information.
- To improve public access to data that informs water resource planning, management, and policy decisions.
Key Provisions and Changes (illustrative, based on typical scope of open data water bills)
Note: The specific statutory language is not provided here, but AB 2728 generally would include provisions such as:
- Establishing or designating a government entity or framework responsible for mandatory collection, storage, and dissemination of water data (e.g., supply sources, allocations, withdrawals, usage, hydrologic trends, infrastructure status, and pricing).
- Requiring data to be collected at defined intervals (e.g., monthly, quarterly) and updated within a specified timeframe.
- Implementing data standards and interoperability requirements to ensure data from multiple agencies (e.g., Department of Water Resources, State Water Resources Control Board, local water agencies) can be accessed and analyzed cohesively.
- Creating an open data portal or expanding an existing one to host datasets, with user-friendly search tools, downloadable formats, and metadata.
- Mandating regular reporting, dashboards, or summaries for executives, policymakers, and the public.
- Provisions to protect sensitive or confidential information while maximizing public access to non-sensitive data.
- Potential funding or appropriations to support data infrastructure, stewardship, and public access initiatives.
- Accountability and enforcement mechanisms for compliance by state and local agencies.
Who Would be Affected
- State agencies that collect, manage, or regulate water data (e.g., Department of Water Resources, State Water Resources Control Board, Department of Fish and Wildlife, regional water quality/control agencies).
- Local and regional water utilities and groundwater sustainability agencies required to report data.
- Policymakers and state planners who rely on water data for decisions.
- Researchers, non-profit organizations, journalists, and the public seeking access to water data.
- Data professionals who would consume, analyze, or integrate water datasets.
Procedural and Timeline Aspects
- History indicates committee consideration and amendments, with multiple referrals between committees.
- Vote history shows positive committee action (unanimous or near-unanimous in earlier stages) and progression toward a suspense file in the Assembly for APPR (Appropriations) consideration.
- As of the latest actions (April 29, 2026), the bill is in the Assembly Appropriations committee on suspense, with the envisaged pathway toward floor passage contingent on budgetary and fiscal considerations typical for APPR review.
- Key dates to track for updates:
- Initial introductions and first readings (February 2026) and subsequent amendments.
- Committee hearings and votes (notably March–April 2026) and re-referals.
- APPR suspense file review and potential amendments or fiscal impact analysis.
Potential Impacts and Implications
- Enhanced transparency: Public access to robust, standardized water datasets can drive better public scrutiny, research, and accountability.
- Improved planning and policy: Timely and interoperable data supports informed decisions on drought response, infrastructure investments, water rights, and sustainability planning.
- Data governance: Establishes or formalizes a governance framework for who collects, maintains, and releases data, including metadata standards and data quality expectations.
- Fiscal considerations: APPR suspense action suggests potential budgetary impacts for data infrastructure, personnel, and ongoing maintenance; final approval may depend on funding alignment.
