The Trinity River watershed provides water to greater than 40% of the Texas human population - a population expected to double by the year 2050. The watershed drains approximately 18,000 square miles across 37 state counties, stretching from the headwaters of the Four Forks Region (Clear Fork, West Fork, Elm Fork and East Fork) in North Texas to its terminus into the Trinity Bay at Galveston Bay, a valuable ecosystem and estuary, that adjoins the Gulf of Mexico. Along the way, the river passes through and serves the domestic water needs of the two largest populaces in the state, Dallas-Fort Worth metroplex in North Central Texas, and Houston in Southeast Texas. Between these two urban areas, the majority of the watershed is comprised of rural communities, where an estimated 95% of the land is privately owned.
