2012 Texas State Water Plan

About

What is this site and what does it do?

As part of our ongoing efforts to promote awareness about water shortages and create transparency, TWDB launched this new interactive website that makes 2012 State Water Plan data easily viewable. This first-of-its-kind online application makes it easy to get details about potential water shortages and water management strategies that regional water planning groups recommended to address them:

  • In multiple planning decades over the next 50 years, with changes over time
  • At the community, state, region, county and entity level
  • With several map layer options

This new website lets water users statewide take an up-close look at data in the 2012 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), and
  • the water management strategies recommended to address potential shortages

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?

  1. Choose a type of water planning data from the four colored menu tabs near the top:
    • Projected Water Demands
    • Existing Supplies
    • Water Needs (potential shortages)
    • Recommended Strategy Supplies
  2. Use the dropdown menus or click on the map or table elements (depending on the view you are in), to select either:
    • the geographic area of interest (region, county, or water user group); or
    • the water usage type (e.g., irrigation), type of strategy (e.g., conservation), or water source of interest
  3. Choose a planning decade (2010 - 2060)
  4. You may also add and/or change map layers by clicking the small icon in the upper right hand corner of the map
  5. Hit the Home link in the upper right corner of the page to reset the page

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: 2010 through 2060.

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 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 2012 State Water Plan is the ninth state water plan and the third 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.

Glossary

For these and other terms, see also the 2012 State Water Plan glossary.
ACRE-FOOT

Volume of water needed to cover 1 acre to a depth of 1 foot. It equals 325,851 gallons.

COUNTY-OTHER

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.

DROUGHT

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.

NEEDS

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).

Needs
RECOMMENDED WATER MANAGEMENT STRATEGY

Specific project or action to increase water supply or maximize existing supply to meet a specific need.

UNMET NEEDS

Portion of the demand for water that exceeds water supply after inclusion of all recommended water management strategies in a regional water plan.

WATER DEMAND

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.

About Us

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 2012 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 2011 Regional Water Plans and the 2012 State Water Plan, including the more than 400 regional water planning group members, consultants, and administrative agencies; staff of the TWDB; Texas Parks and Wildlife Department, Texas Department of Agriculture, Texas Commission on Environmental Quality, and other state and federal agencies; and the individuals and organizations that provided public input during 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 20 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.

Interactive 2012 Texas State Water Plan

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, 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 sent 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.

Data Sources

All data presented are based on the sixteen 2011 Regional Water Plans and the 2012 State Water Plan. The water planning data are based on the Regional Water Planning Data Application used to collect data from the regional water planning groups.

Summaries of the data presented were published in the 2012 State Water Plan.

For a list of rolled-up recommended water management strategies please see Appendix A.2 of the 2012 State Water Plan.

In the future, we will be adding information regarding projected population, water demands, existing water sources, identified water needs, and other associated data.
