Trinity River National Wildlife Refuge was established on January 4, 1994 with an initial purchase of 4400acres. Since that time, the refuge has acquired additional acreage which now totals 30000acres. The primary purpose of establishing this refuge is to protect a portion of the bottomland hardwood forest ecosystem along the Trinity River located in southeastern Texas. The refuge, which is a remnant of what was once a much larger natural area is a broad flat floodplain made up of numerous sloughs, oxbow lakes, artesian wells, and tributaries.
