In a December 2012 blog post, I discussed the tensions raised by “Water for Texas 2012 State Water Plan” between the expected population growth and available water resources in Texas. As water demand is expected to rise, existing water supplies are diminishing.
These critical water supply constraints are again brought into sharp focus by the population projections contained in a March 5, 2015 report released by the Office of State Demographer. The 40-year projections (2010 to 2050) indicate that if the migration patterns observed in Texas between 2000 and 2010 continue at the same rate, the population of Texas will double, representing a significant increase in projections contained in the 2012 State Water Plan. The projected water resource shortages will be exacerbated.
The 2012 State Water Plan, based on a 50-year horizon, projected a 2060 population of 46.3 million. New population numbers, based on the recent migration patterns, project an increase from the 2010 Census population of 25.1 million to a 2050 population of 54.4 million.
For the past 10 years, Texas experienced the largest annual population growth of any state. Will the Texas economy maintain its strength to support job growth that will attract young workers from around the country and the world? Can the associated high net migration be sustained? What will be the impact of this growth? How will the environmental impacts be anticipated and managed?
The areas of fastest growth include the areas in and around Dallas/Ft. Worth, Austin/San Antonio, and Houston. Cities in those areas are making plans to secure long-term water supplies. Will they be successful? Will regulatory changes have to be made to surface and groundwater water rights to effectively and efficiently acquire, manage, and conserve these limited water resources? Will the infrastructure be there? How will it be financed?
Will Texas have “cool, clear water”?
