The El Negro Ranch and a series of named water-drawing landmarks define this landscape in the Rio Grande Valley hinterlands. During the early 21st century, the area remained a sparse ranching environment where life centered around critical infrastructure like the San Ignacio Windmill Number One, San Ignacio Windmill Number Two, and Borrachito Windmill. These features indicate the necessity of groundwater management in a region defined by its wide spacing and limited surface water.
