The waterway we refer to as the San Antonio River Watershed is actually a collections of creeks and tributaries whose main source is the Edwards Aquifer. The longest members are the Medina River and Cibolo Creek. The Medina river was named after Pedro Medina in 1689, a Spanish engineer. Once, it served as the official boundary between Texas and Coahuila, Mexico. At the time, the San Antonio River was considered its tributary and the river was called Rio Medina all the way to the Gulf of Mexico. Just south of San Antonio in 1813, the bloodiest battle in Texas history was fought, although the exact location of the “Battle of Medina” remains a mystery. Cibolo Creek begins ten miles northwest of Boerne in Kendall County and runs southeast for about 100 miles, forming the county line between Bexar, Comal, and Guadalupe Counties. It was called “Xoloton” by the early Coahuiltecan Indians of the area and was renamed Rio Cibolo during a Spanish expedition in 1721. Rio Medina and Rio Cibolo cradled the early Texas civilization like our own Tigris and Eufrates. Many shorter contributors feed into these seminal waterways including the San Antonio River, Leon Creek, Medio Creek and Salado Creek. My current work for the Lila Cockrell Theater is all about flow--the flow of water and the flow of time. The confluences of people in this area have been, at times, harmonious, violent, constructive and often surprising (like building Toyota trucks on the site of the oldest ranch in Texas along the Medina River). Just as the numerous smaller waterways around San Antonio all converge to form one life-giving system, we as individuals and individual cultures work together throughout time, to produce the continuous flow of history. My work celebrates the confluence of water and people in and around San Antonio.
