  • Texas has 16 regional water planning groups, one for each planning area. There are now 12 interests represented on each planning group.Legislation passed during the 82nd Legislative Session now requires that groundwater conservation districts in each groundwater management area located in the regional water planning area to appoint one representative to serve on the regional water planning group.
  • Regional water planning groups compare existing water supplies with current and projected water demands to identify when and where additional water supplies are needed for water user groups and wholesale water providers.If existing supplies do not meet future demand, they recommend specific water management strategies to meet water supply needs, such as conservation of existing water supplies, new reservoir and groundwater development, conveyance facilities to move available or newly developed water supplies to areas of need, water reuse, and others.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.
  • Water demand is projected to increase by 22 percent.Existing water supplies—categorized as surface water, groundwater, and reuse water—are projected to decrease about 10 percent.(Needs are more than the difference between supply and demand because supplies are not always available to all users throughout a region.)
  • We do not have enough existing water supplies today to meet the demand for water during times of drought.In the event of severe drought conditions, the state would face an immediate need for additional water supplies of 3.6 million acre‐feet per year with 86 percent of that need in irrigation and about 9 percent associated directly with municipal water users. Total needs are projected to be 8.3 million acre‐feet per year by 2060.(Needs are more than the difference between supply and demand because supplies are not always available to all users throughout a region.)The strategies recommended by regional water planning groups would provide, if implemented, 9.0 million acre‐feet per year in additional water supplies by 2060.These strategies included 562 unique water supply projects.Twelve planning groups were unable to meet all water supply needs for each water user group in their planning areas. Approximately 2.2 million acre-feet of water supply needs are unmet in 2010, increasing to approximately 2.5 million acre-feet in 2060. Irrigation represents the vast majority (98-99 percent) of unmet needs in all decades. The major reason for not meeting a water user group’s water supply need is that the planning group did not identify an economically feasible water management strategy to meet the water supply need.
  • By 2060, new surface water strategies produce 5 times the volume produced by new groundwater strategies.Operational changes: operation of reservoirs as a system to increase yield; reallocation of reservoir storage from flood control or hydro-electric power generation to water supply“Other” surface water strategies: existing water that is not legally or physically available
  • Volume in 2010: 19,672 acre-feetVolume in 2060: 1,499,671 acre-feet
  • Water providers surveyed during the planning process reported an anticipated need of $26.9 billion in state financial assistance to implement municipal water management strategies in their planning areas. This amount represents about 58 percent of the total capital costs for water supply management strategies recommended for municipal water user groups in the 2011 regional water plans.
  • The legislature should provide a mechanism to acquire feasible reservoir sites so they are available for development of additional water supplies to meet identified in the regional water plan and beyond.The legislature should enact statutory provisions that eliminate unreasonable restrictions on the voluntary transfer of surface water from one basin to another.The legislature should remove TWDB from the petition process concerning the reasonableness of a desired future condition except for technical review and comment.The legislature should require all retail public utilities to conduct water loss audits on an annual basis, rather than every 5 years.The legislature should develop a long-term, affordable, and sustainable method to provide financing assistance for the implementation of the state water plan.
