2027 State Water Plan
The 2027 State Water Plan was adopted by the Board on July 23, 2026.
The 2027 State Water Plan marks 25 years of Texas’ widely recognized regional water planning process and represents the sixth plan developed through the collaborative work of hundreds of stakeholders across the state. Built on extensive data, science, and a strong statutory framework, the planning process requires all 16 regional water planning groups to openly assess and address their future water supply needs. The 2027 plan identifies thousands of actionable strategies and projects—complete with projected costs and sponsoring entities—that show how Texas can meet its water needs and remain resilient during future droughts. This information provides a critical roadmap for ensuring that Texas communities continue to have reliable water supplies both now and in the future.
This initial document, along with the associated interactive state water plan, was developed on an accelerated timeline to support 2026 State Water Plan Implementation Fund for Texas (SWIFT) financial assistance commitments. An amendment to this document is anticipated prior to the January 5, 2027 statutory deadline to incorporate additional and more robust content in line with previously adopted state water plans.

- Recommended new major water supply reservoirs map - These recommended reservoir footprints or representative locations may be hypothetical locations of facilities for regional water planning purposes only as it relates to planning-level cost estimates. The locations on this map may be conceptual in nature and may not represent actual locations of facilities. Siting of facilities are subject to studies, designs, engineering, and/or contract negotiations to be determined by the project's sponsor at a later date.

Supporting data spreadsheets
- Projected needs of every water user group, as a share of total demand (percent) - Water supply needs expressed as a percent of the water user group's total demand provide an indicator of the severity of need. The larger the percent of an entity's total demand indicates a more severe potential shortage. Bolded text in the table indicates that the needs identified are not fully met by the strategies recommended in the plan.
