Espada Aqueduct (San Antonio, Texas)

            Historic Espada Aqueduct (or Espada Acequia) in San Antonio, Texas.  The aqueduct was built by Franciscan friars in 1731 to supply irrigation water to the lands near Mission San Francisco de la Espada.  A network of irrigation ditches (referred to as the Acequias of San Antonio) were constructed in San Antonio between 1718 and 1744.  

The Acequias of San Antonio was recognized as a National Historic Civil Engineering Landmark in 1968 by the American Society of Civil Engineers (ASCE).  Their description of the landmark states:

“The Acequias of San Antonio are among the earliest engineered water supply and irrigation systems recorded in the United States. The Acequias served an integral role in the growth and stability of the San Antonio community for nearly 200 years. The eight canals, totaling 15 miles in length, were built by Spanish settlers who learned the technique from the Moors. Each acequia was a complicated system of storage dams, floodways, control gates, canals, sluices, and distribution ditches.”

The Espada Aqueduct was designated as a National Historic Landmark in 1964 and added to the National Register of Historic Places in 1966.
