Mission San Juan: The Acequia That Still Flows
Near San Antonio, Texas
The ditch that delivers water to Mission San Juan's farm fields today was hand-dug in the seventeen hundreds. The San Juan Acequia, an irrigation channel routed from the San Antonio River to the mission's croplands, is one of the oldest continuously operating water-delivery systems in North America, a piece of infrastructure that has outlasted the Spanish Empire, Mexican sovereignty, the Republic of Texas, and the United States frontier era. It still flows.
Mission San Juan Capistrano was born far from here. Spanish Franciscans established it in seventeen sixteen in far east Texas among the Nazoni and Nadaco peoples, naming it San José de los Nazonis. But the eastern Texas missions struggled, underfunded and exposed, and in seventeen thirty-one the Spanish Crown ordered them relocated to the already-established community on the San Antonio River. On March fifth of that year, the mission was formally renamed and resettled at its current site, several miles south of the Alamo.
At San Juan, the Coahuiltecan-speaking peoples who entered the mission community learned Spanish farming methods, mastered the acequia system, and produced enough surplus to supply other settlements in the region. By the middle of the eighteenth century, Mission San Juan operated cattle ranches, grew corn and vegetables, and traded its surplus through the river missions network. The stone friary and the unfinished church visible today date from the later eighteenth century.
The mission fell into decline after Mexican independence and secularization in the eighteen thirties, but Catholic worship slowly resumed under Bishop John Odin in the eighteen forties. Today Mission San Juan is one of five San Antonio missions designated as a UNESCO World Heritage Site in twenty fifteen, the first in Texas. The San Antonio Food Bank now farms the mission's historic fields using the same acequia system the Franciscans engineered nearly three centuries ago.
