Bill Summary · HB 25

Legislative bill overview

HB 25 establishes a new permitting process for reservoir augmentation projects in Maryland, allowing the state to approve and regulate initiatives that increase water storage capacity. The bill creates a formal legal framework for evaluating, approving, and monitoring these water infrastructure projects. It became law in May 2025 after passing both chambers and receiving gubernatorial approval.

Why is this important

Maryland faces periodic water supply challenges, particularly during droughts, and reservoirs are critical infrastructure for managing freshwater resources for agriculture, municipalities, and industry. This legislation enables the state to systematically develop additional water storage capacity to meet growing demand and climate resilience needs. The permitting process provides a structured way to balance infrastructure development with environmental and community considerations.

Potential points of contention

  • Environmental impact concerns – Reservoir projects can affect wetlands, fish migration, stream ecosystems, and wildlife habitats; the permitting criteria may determine whether environmental protections are adequate
  • Water rights and competing interests – Agriculture, residential users, and industrial stakeholders may compete over water allocation from augmented reservoirs, raising questions about fair distribution
  • Project costs and public burden – Uncertainty about who bears construction and maintenance costs, and whether ratepayers or taxpayers will fund augmentation projects
