What is this site and what does it do?
This website is an integral part of the 2017 State Water Plan that lets water users statewide take an up-close look at data in the 2017 State Water Plan and how water needs change over time. The user-friendly website, which is also easily viewed on most mobile devices, now shows:
- projected water demands,
- existing water supplies,
- the relative severity and projected water needs (potential shortages),
- the water management strategies recommended to address potential shortages, and
- recommended capital projects and their sponsors.
over the next 50 years in geographical and tabular forms. Note that all county-based water user group categories are mapped to the same location at the center of each county.
How do I find the information I'm looking for?
A good place to start is the ‘View data for’ drop down menu found in the upper left of the home page. From this drop down you can navigate to pages with state water plan data organized by a specific area of interest or data type.
Once you’ve navigated to a specific page you can start exploring the data related to that topic/area. Each page will contain demand, existing supply, need (potential shortage), and strategy supply data related to that page topic. The data are presented in a variety of formats such as graphs, figures, tables, and maps. Many of the page elements are interactive so you can hover over and click elements to show more detail, use embedded search and sort functions to locate information, or click hyperlinks to navigate to other pages in the application. If you are interested in digging deeper and interacting more with the data on a page, scroll down to the ‘Raw Data’ section. In addition to reflecting the decade and theme button selections in the banner above the map, the data displayed in this section can be filtered and sorted using the drop-down boxes below the ‘Raw Data’ section heading. The column toggles allow you to control the aggregation levels of the data.
- To change an existing column, update that selected drop-down to another item in the list
- To remove an existing column, update that selected drop-down to the blank entry in the list
- To add a new column, select it from the ‘Sub Dimension…’ drop down list
Additionally, you can filter by specific data within the table using the 'solo' feature. To do this, hover the mouse over the data element you wish to filter by until a 'solo' button appears. Selecting this feature will filter all the data in the table based on your selection. Multiple filters may be added using the same method, and all applied filters will be listed in the area above the column headers. To remove a solo filter, simply click the 'X' button to the left of the item listed in the area above the column headers.
How do I use the interactive map?
Interactive maps are included to view and explore the state water plan data geographically. Here are some tools that will help you navigate and use the maps:
- Pan – To move the map; click and hold the left mouse button and drag the map to a new place.
- Zoom – To see more details or a larger area on the map you can zoom in and out using the +/- sign buttons in the top right. Double left clicking your mouse on a map area will also zoom you into that location.
- Statewide View – To quickly view all of Texas click on the button in the upper right with the Texas graphic.
- Lock Extent – To freeze the map at a specific location and zoom level click the lock button on the right side of the screen. The button will darken when turned on and lock the map extent as you click through the different theme and decade buttons. This function may be turned off by clicking the lock button a second time.
- Map Information – Symbol descriptions, notes, and disclaimers may appear just below the map panel to provide more information about what is being displayed.
- Hover Labels – Some map items will display labels when you hover your mouse over them. Clicking on any of these items will navigate you away from the current page to a page related to that item in the interactive state water plan.
- Decade Buttons – These are in the banner above the map and filter the map data by decade. For example, Project symbols will begin displaying on the map in the decade that matches the project’s online decade and continue to show in all subsequent decades.
- Theme Buttons – These are in the banner above the map and filter the map data by type.
- Symbol Popups – You can click on individual symbols to open a popup displaying data associated with that item. If there are overlapping symbols clicking on the cluster will cause them to spread out and allow you to select each one individually.
Due to the nature of the state water plan data not everything is relevant to display on the map. Please keep the following in mind when exploring the interactive maps:
- The map for a selected region page will only display projects that benefit water user group splits within that planning region.
- Sources will only display in the map if at least one water user group has an existing supply or water management strategy supply amount greater than zero tied to it in the selected decade.
- Only the following sources are mapped: groundwater, indirect reuse, reservoir, system, run-of-river, and seawater.
- If an unmapped source type (EX: Direct Reuse) has related WMS WUG supplies or a project with capital costs, it will be represented on the map by the location of the project and/or benefiting WUG.
- If a water user group is related to a zero value for a specific theme and decade it will not display on the map, except for WUGs with zero associated population on the project page. For example, the needs map theme will not display a WUG point if they have zero needs in the selected decade.
- Information about recommended WMS projects that are not specifically associated with water user groups are displayed on the WMS Project application page although, because the water supply is not assigned to water user groups, neither the WMS project or associated supply will display on any of the other application pages until that strategy supply has been assigned to a water user group. These types of projects are recommended by the region to develop supply where a benefiting water user group has not yet been identified.
State Water Plan Data
Development of the state water plan is central to the mission of the TWDB. Based on 16 regional water plans, the plan addresses the needs of all water user groups in the state – municipal, irrigation, manufacturing, livestock, mining, and steam-electric power – during a repeat of the drought of record that the state suffered in the 1950s. The regional and state water plans consider a 50-year planning horizon: 2020 through 2070.
During each five-year planning cycle, planning groups evaluate:
- population projections,
- water demand projections, and
- existing water supplies that would be available during times of drought.
Planning groups identify:
- water user groups that will not have enough water during times of drought, and
- recommend strategies and projects that could be implemented to address shortages.
At the end of each five-year regional water planning cycle, agency staff compiles information from the approved regional water plans and other sources to develop the state water plan, which is presented to TWDB's governing Board for adoption. The final adopted plan is then submitted to the Governor, Lieutenant Governor, and the Texas Legislature.
The 2017 State Water Plan is the tenth state water plan and the fourth plan based on the regional water planning process. In addition to incorporating the regional water plans, the state water plan serves as a guide to state water policy.
How are the locations of the projects determined?
Water “projects” are the future capital investments in infrastructure that support water management strategies. Capital project symbols (red triangles) are mapped to a single point as a necessary simplification to represent a geographic location of each water project (e.g., well fields, reservoirs, pipelines) solely for the purposes of representing the water plan visually. The basis for selecting each representative location varied depending on the regional water plan and particular type of infrastructure but, in general, the default project locations relate to:
- approximate locations of at least one component of major infrastructure such as dams, water treatment plants, water intakes for pipelines, or well fields proposed in the plan; or
- the primary location of the water user group in which certain types of infrastructure would be located, such as some water treatment plants within a city or water conservation investments; or
- the centroid of the county in which a project with dispersed infrastructure would be located, such as county-wide irrigation, mining, or manufacturing conservation projects; or
- the centroid of a county-aquifer polygon for certain, generalized groundwater supply projects.
The actual locations and physical extent of recommended projects will vary and, in many instances such as pipelines, will encompass multiple geographic locations and facilities.
For these and other terms, see also the 2017 State Water Plan glossary.
Volume of water needed to cover 1 acre to a depth of 1 foot. It equals 325,851 gallons.
An aggregation of residential, commercial, and institutional water users in cities with less than 500 people or utilities that provide less than an average of 250,000 gallons per day, as well as unincorporated rural areas in a given county.
Term is generally applied to periods of less than average precipitation over a certain period of time. Associated definitions include meteorological drought (abnormally dry weather), agricultural drought (adverse impact on crop or range production), and hydrologic drought (below average water content in aquifers and/or reservoirs).
DROUGHT OF RECORD
Period of time during recorded history when natural hydrological conditions provided the least amount of water supply. For Texas as a whole, the drought of record is generally considered to be from about 1950 to 1957.
EXISTING WATER SUPPLY
Maximum amount of water available from existing sources for use during drought of record conditions that is physically and legally available for use.
Projected water demands in excess of existing water supplies for a water user group or a wholesale water provider. (i.e., potential shortage if no water management strategy is recommended).
RECOMMENDED WATER MANAGEMENT STRATEGY
Specific project or action to increase water supply or maximize existing supply to meet a specific need.
Portion of the demand for water that exceeds water supply after inclusion of all recommended water management strategies in a regional water plan.
Quantity of water projected to meet the overall necessities of a water user group in a specific future year.
WATER USER GROUP
Identified user or group of users for which water demands and water supplies have been identified and analyzed and plans developed to meet water needs. Water user groups are defined at the county level for the manufacturing, irrigation, livestock, steam-electric power generation, and mining water use categories. Municipal water user groups include (a) incorporated cities and selected Census Designated Places with a population of 500 or more; (b) individual or groups of selected water utilities serving smaller municipalities or unincorporated areas; and (c) rural areas not included in a listed city or utility, aggregated for each county.
Data is available for you to download as Comma-Separated Value (.csv) files through links at the bottom of each application page. Downloads of statewide datasets are available at the bottom of the application homepage, and all water volumes are in units of acre-feet/year.

This website is a product of the Texas Water Development Board (TWDB). This project is part of our ongoing efforts to communicate information from the 2017 State Water Plan to planners, scientists, policy makers, and the public.
TWDB is charged by the Texas Legislature with administering the regional water planning process and developing a state water plan every five years. The data presented are the result of that process and are based on the expertise of numerous people and organizations throughout the state of Texas who participated in development of the 2016 Regional Water Plans, including the more than 450 regional water planning group members, consultants, and administrative agencies; staff of the TWDB; Texas Parks and Wildlife Department, Texas Department of Agriculture, and Texas Commission on Environmental Quality; and the individuals and organizations that provided public input throughout the planning process.
How Do We Plan?
Water planning in Texas starts at the regional level with 16 regional water planning groups, one for each of the 16 designated planning areas in the state. Each planning group consists of about 25 members who represent at least 12 interests, as required by Texas statute, including agriculture, industry, public, environment, municipalities, business, water districts, river authorities, water utilities, counties, power generation, and groundwater management areas.
During each five-year planning cycle, planning groups evaluate population projections, water demand projections, and existing water supplies that would already be available during times of drought for 2,600 water user groups. Planning groups identify water user groups that will not have enough water during times of drought, recommend strategies that could be implemented to address shortages, and estimate the costs of these strategies. While carrying out these tasks, planning groups assess risks and uncertainties in the planning process and evaluate potential impacts of water management strategies on the state's water, agricultural, and natural resources.
Once the planning groups adopt their regional water plans, they are submitted to the TWDB — the state's water supply planning and financing agency — for approval. TWDB then compiles the state water plan, which serves as a guide to state water policy, with information from the regional water plans and policy recommendations to the Texas Legislature. Each step of the process is open to the public and provides numerous opportunities for public input.
All data presented are based on the sixteen 2016 Regional Water Plans and the 2017 State Water Plan. The water planning data are based on the Regional Water Planning Data Application used to collect data directly from the regional water planning groups.
Statewide summaries of the data presented were published in the 2017 State Water Plan.
