Acknowledgmentsiv2017 State Water Plan Texas Water Development Board
The 2017 State Water Plan would not have been possible without the time and expertise of numerouspeople and organizations throughout Texas. The Texas Water Development Board (TWDB) would like toexpress its sincere appreciation to all who participated in the development of the 16 regional waterplans and this state water plan: the more than 450 regional water planning group voting members(listed below), their consultants, and their administrative agents (listed below); staff of the TWDB; TexasParks and Wildlife Department, Texas Department of Agriculture, Texas Commission on EnvironmentalQuality, and other state and federal agencies; and the individuals and organizations that provided publicinput throughout the planning process.Finally, we would like to thank the leadership of the State of Texas for their consistent support andrecognition of the importance of water planning.Regional Water Planning Group Voting Members(Region – member) *planning group chairs at the time the 2016 regional water plans were adoptedA - Autrey, EmmettA - Bailiff, TomA - Baumgardner, JoeA - Clark, NolanA - Cook, VernonA - Cooke, CharlesA - Cooke, DeanA - Crowell, AmyA - Derington, JimA - Gibson, RickA - Gilmore, RustyA - Green, GlenA - Guthrie, JanetA - Hallerberg, BillA - Keys, SandyA - Kidd, BobbyA - Kleuskens, TonyaA - Krienke, DannyA - Landis, DavidA - Meyer, RobertA - Satterwhite, KentA - Skaggs, GradyA - Smith, LynnA - Stephens, BeverlyA - Sweeten, John M.A - Tregellas, JanetA - Walthour, SteveA - Weber, JayA - Weinheimer, BenA - Williams, C.E.*A - Williams, John C.B - Armstrong, TamelaB - Banks, JimmyB - Bell, CharlieB - Brite, J.K.
