About this map

The International Jurisdictional Line bisects Falcon Reservoir, marking the aqueous border where the Rio Grande Rio Bravo flows between Texas and Tamaulipas. In this late 1970s landscape, the map captures a significant cross-border geography, detailing both American and Mexican shorelines. On the Texas side, developments like Falcon Mesa and Siesta Shores sit near the reservoir's northern reaches, while the Mexican side features a scattering of settlements such as Miragua, San Angelo, and Solomoneño.

A notable highlight is the location of Guerrero Viejo, positioned on the edge of the reservoir's inundation zone where the Rio Salado enters the main basin. The map illustrates the complex shoreline created by the damming of the river, showing numerous inlets and peninsulas like La Isla and Listas Coloradas. This survey serves as a vital record for understanding the modern binational water management and the specific location of small ranching or residential communities like El Charrito and Nuevo Jardin before further regional changes.
