1956 Map of Olmito

About this map

Meandering resacas and intricate irrigation systems define this landscape in Cameron County, where ancient distributary channels of the Rio Grande have been integrated into a complex agricultural network. The settlement of Olmito serves as a local hub near the southern edge, while smaller communities like Russelltown and Villa Cavazos are linked by a grid of roads and elevated ditches. The hydrology of the region is striking, featuring the winding Resaca de los Cuates, Resaca del Jardin, and Resaca de la Palma, which provide vital water storage in an otherwise arid environment. Evidence of large-scale water management is visible through features such as the Main Supply Canal and various spoil banks. This 1956 survey, with updates from the early 1980s, captures the transition of traditional ranch lands, like Wardner Ranch, into more intensive farming and managed drainage systems.
