About this map

The agricultural landscape of the Rio Grande Valley is defined here by a sophisticated network of irrigation and drainage infrastructure crossing the Hidalgo and Willacy county line. Central to this system is Delta Lake, divided into Unit No 1 and Unit No 2, which serves as a vital water resource managed by the Hidalgo and Willacy Counties Water District No 1. The map reveals how the desert-like terrain was transformed for cultivation through features like the Main Supply Canal, the Salt Lake Drain, and an Aqueduct.

Settlement patterns are concentrated around Lasara and Monte Alto, supported by the Missouri Pacific railroad line. For genealogists, the map is particularly detailed regarding burial sites, noting the Lasara Memorial Cemetery, Garcia Cemetery, and the Stockholm Cemetery near the southern boundary. These named cemeteries and the numerous pumphouses scattered along the ditches underscore the dual importance of family heritage and water management in this South Texas region.
