Trinity River Authority
The Trinity River Authority (TRA) was formed in 1955 by the Texas legislature. Its main concerns are water supply and water conservation in the Trinity River Basin. The authority extends over , including all or part of 17 counties. The general offices of the authority are located in Arlington, Texas. TRA is a self-funded entity from its operations; it receives no state appropriations or taxes. Leadership
TRA is governed by a 25-member board of directors, all of whom are appointed by the Governor of Texas for six-year terms. Roughly 1/3 of the board is reappointed or replaced every two years. The board, in turn, hires the General Manager, who oversees TRA's operations. Under the statute creating the TRA, the board members are appointed as follows:
Four members must be appointed from residents of Dallas County
Three members must be appointed from residents of Tarrant County
One member must be appointed from residents of each of the following counties (15 in total): Anderson, Chambers, Ellis, Freestone, Henderson, Houston, Kaufman, Leon, Liberty, Madison, Navarro, Polk, San Jacinto, Trinity, and Walker
Three members are appointed at-large but must be residents of a county within TRA's jurisdiction
