1982 Map of Indio Tank

About this map

San Ambrosia Creek carves a winding path through the arid landscape of Maverick County, serving as the primary drainage for this stretch of South Texas. This 1982 provisional survey captures the region’s reliance on water management for ranching and land use, evidenced by a series of named earthen reservoirs such as Indio Tank, McFarland Tank, and Rock Tank. These features represent the essential infrastructure required to sustain life and livestock in the brush country. The map also records a small Landing Strip situated in the central-east, providing a point of aerial access for remote ranch operations. The intricate contour lines reveal a terrain of subtle ridges and draws typical of the Rio Grande basin hinterlands during the late twentieth century.
