Texas Instream Flow Studies: Programmatic Work Plan
The Programmatic Work Plan for Texas Instream Flow Studies is intended to outline the scope, timeframe, and methodology for planning and conducting priority studies. It also describes the responsibilities of the Texas Water Development Board (TWDB), the Texas Parks and Wildlife Department (TPWD), and the Texas Commission on Environmental Quality (TCEQ), who will jointly conduct the studies, as mandated in Section 16.059 of the Texas Water Code. Study results will be incorporated into future regional and state water plans, and will become essential data for conservation of fish and wildlife resources and consideration in the state water rights permitting process.
Texas Instream Flow Studies: Technical Overview
Senate Bill 2, enacted in 2001 by the 77th Texas Legislature, established the Texas Instream Flow Program, which is jointly administered by the Texas Commission on Environmental Quality, Texas Parks and Wildlife Department, and Texas Water Development Board (hereafter referred to as “the Agencies”). The purpose of the program is to perform scientific and engineering studies to determine flow conditions necessary for supporting a sound ecological environment in the river basins of Texas. This document identifies a process for developing and conducting those studies.
