San Antonio has a plethora of fun facts, but did you know that the only Spanish aqueduct in the US is located in the Alamo City? We’re taking you on a field trip to the San Antonio Missions National Historical Park and learning about this elder waterway.
Go with the flow
The TL;DR on aqueducts is that these are man-made waterways — usually in the shape of bridges — designed to carry water from a source to a different destination. Fun fact: The word “aqueduct” stems from Latin aqua + ducere, meaning “to lead water.”
Constructed in the 18th century (between 1740 and 1745) by the Spanish, the Espada Aqueduct carries water across a ~300-ft stone bridge south from Piedras Creek to Mission Espada. At the time, the six-mile acequia irrigation route was used for the mission’s farm land and allowed the commune to have a source of running water.
A dam miracle
The Espada Dam was essential to the mission’s survival, as it worked in tandem with the acequia to supply drinking + irrigation water. The dam still diverts water into the Espada Acequia System, and can be seen today via a short walk from the parking lot. It’s also the last surviving Spanish-built dam in San Antonio.
Fun fact: The San Juan Acequia system supplies water to the San Juan Farm which is activley managed by the National Park Service.
