John Ashworth has a wide range of experience with water-supply evaluations and water-resource management planning in his 23 years of working for the Texas Water Development Board, and now for LBG-Guyton Associates. He currently directs the firm's water management planning activities for several of the Texas regions designated by Senate Bill 1. The regional water management plans involve analyses of available water supplies to meet short- and long-term water needs for all water-use categories. The plans also provide for drought contingency water-supply strategies. His experience as a geologist with the Texas Water Development Board involved the supervision of the agency's ground-water availability studies. This duty included the identification, characterization and supply analysis of the major and minor aquifers in the state. Additional duties included the supervision of the Priority Ground Water Management Area (Critical Area) Program, Texas/Mexico Border Ground-Water Program, technical assistance to underground water conservation districts and other public entities, and involvement with the Aquifer Storage and Recovery Pilot Program. Mr. Ashworth's experience with Gas Log Inc. included the evaluation of gas shows during oil field drilling operations and correlation with geophysical log interpretations. This activity resulted in his familiarity with large-scale drilling operations.
