Water plays a central role in shaping the ecosystems of Southeast Texas. Rivers, wetlands, lakes, and coastal systems provide habitat for wildlife, support plant communities, and supply water for communities throughout the Trinity River basin.
The Lower Trinity River Basin
The Trinity River is one of the major river systems in Texas and flows through the heart of the Lower Trinity Basin region. Floodplains, wetlands, and bottomland hardwood forests along the river support a wide range of wildlife and plant species.
Wetlands and Aquatic Habitats
A watershed is an area of land where rainfall and surface water drain into a common river, lake, or coastal system. Protecting watersheds helps maintain water quality, reduce erosion, and support healthy ecosystems throughout the region.
