Archaeological monitoring of the Ashby Street drainage project, San Antonio, Bexar County, Texas

In April 1987, the authors monitored excavation of trenches for a drainage project in the area of North St. Mary's and Ashby Streets north of downtown San Antonio. The main concern was to observe and record the location and configuration of the Upper Labor Acequia in this area when it was crossed by trenching machines. A cross section of the acequia was recorded at the intersection of St. Mary's and Myrtle Streets.
