Lake Casa Blanca has provided water recreation for the south Texas area for more than 50 years. The lake has 1,680 surface acres and is an impoundment of Chacon Creek, a tributary of the Rio Grande.
Webb County and the city of Laredo originally ran this park. After signing a 50-year lease, the state opened the park as Lake Casa Blanca International State Park in 1991. The 525-acre park sits on the eastern city limit of Laredo.
Archeological sites in the park indicate the presence of humans for around 3,000 years. Artifacts found in the area indicate that humans have been passing through south Texas for 11,000 years.
Cabeza de Vaca, an early Spanish explorer, came through this area on foot in 1535. He found a relatively intact, highly mobile culture made up of small bands of hunting and gathering peoples. They depended on the seasonal availability of small game, prickly pear fruit, mesquite beans, mussels and snails.
In the 1600s, the Lipan Apache and Tonkawa, followed by the Comanche, arrived in south Texas on horseback and disrupted the hunter-gatherers’ way of life. Disease took its toll, also. After the Spanish established missions in this area in the early 1700s, the native bands were quickly absorbed, and their culture and language were largely lost.
The Rio Grande corridor has been the source of many conflicts. Disputes over the border between Texas and Mexico, and later between the United States and Mexico, simmered throughout the 19th century. Even into the 20th century, civil unrest in Mexico often spilled across the river into what is now Texas.
