The park is located on Lake Texana, a reservoir on the Navidad River, which covers 11,000 surface acres, with approximately 125 miles of shoreline. Lake Texana was named for the historic town of Texana, founded in 1832, near the junction of the Navidad and Lavaca rivers downstream from the present dam site.
Interpretive programs are available for groups by special arrangements.
Summer interpretive programs are held on Saturday mornings and afternoons. The Texas State Park Store sells Lake Texana gift items, ice, firewood, and rents canoes and paddle boats. The park is located in the flat Gulf Coast Vegetational Region, but the majority of the park land consists of mixed oak and pecan woodlands associated with the Navidad River. White-tailed deer, squirrels, rabbits, armadillos, and raccoons are numerous. Alligators are found in the park coves and should not be approached or fed.
