State water plans serve as a cornerstone for integrated water resources management across the United States. Developed through collaboration among state agencies, regional authorities, local governments, and stakeholders, these plans assess current and future water conditions, promote best management practices, and outline strategic actions to ensure reliable, sustainable water supplies.

Collectively, state water plans help:

• Evaluate the status and trends of surface water and groundwater resources
  Identify water-related challenges and risks
• Coordinate planning across regions and sectors
• Recommend policy, infrastructure, and management solutions
• Support long-term resilience for communities, ecosystems, and economies

Below is a representative selection of state and regional water plans prepared by water agencies across the country. Users can search or filter plans by keyword to locate documents relevant to specific geographies, topics, or planning approaches.

Selected State and Regional Water Plans

2010 Regional Water Supply Plan (Florida)

Agency: Southwest Florida Water Management District (SWFWMD)

Overview:
This plan evaluates projected water demands and identifies potential water supply sources for Southwest Florida from 2010 through 2030. Organized into four regional volumes, Northern, Tampa Bay, Heartland, and Southern, the plan emphasizes data-driven analysis and regional coordination to support long-term water supply reliability.

2012 Annual Report: Sustainable Attainable (Maryland)

Agency: Maryland Department of Planning

Overview:
Maryland’s comprehensive planning approach integrates water resources into statewide growth and land-use planning. Mandated by legislation, local plans must address drinking water, wastewater, and future growth. Guided by smart growth principles, the plan supports sustainable development, protection of agricultural and forested lands, and restoration of the Chesapeake Bay.

Focus Areas: Comprehensive Planning, Water Resources Planning

2012 Integrated Resource Plan (Connecticut)

Agency: Connecticut Department of Energy and Environmental Protection

Overview:
Although primarily energy-focused, this plan includes assessments relevant to water resources planning and management, recognizing the interdependencies between water availability, energy generation, and infrastructure capacity.

Focus Areas: Water Resources Planning and Management

2012 Water Quality Integrated Report (Louisiana)

Agency: Louisiana (Clean Water Act Reporting)

Overview:
Prepared to meet federal Clean Water Act requirements, this report evaluates the condition of surface waters across the state. It assesses compliance with water quality standards and identifies suspected sources of impairment for designated uses such as recreation, aquatic life, and public water supply.

Focus Areas: Water Quality

2012 State Water Plan (Idaho)

Agency: Idaho Water Resource Board
