Bill Summary · SB 1335

Legislative bill overview

SB 1335 establishes requirements for water banking entities in Arizona to submit annual reports and make those reports publicly accessible online. The bill mandates transparency in how water banks operate and manage stored water resources, with specific posting and reporting timelines.

Why is this important

Water banking is a critical mechanism for managing Arizona's water supply during drought periods and ensuring long-term water security. Public reporting requirements increase transparency and allow stakeholders—including policymakers, farmers, municipalities, and citizens—to monitor how water reserves are being accumulated and deployed. This visibility is essential given Arizona's dependence on Colorado River allocations and ongoing water scarcity challenges.

Potential points of contention

  • Proprietary information concerns: Water banks may argue that detailed reporting on storage volumes, withdrawal patterns, and financial arrangements could expose competitive or sensitive business information to competitors or affect water market pricing
  • Administrative burden and costs: Smaller water banking operations might face disproportionate compliance expenses for annual reporting and web posting infrastructure
  • Report content specificity: Ambiguity about what data must be included (pricing, customer details, reserve projections, etc.) could lead to disputes between regulators and water banks over adequate disclosure levels
