Rio Grande Rio Bravo defines the international boundary between Texas and Tamaulipas, anchoring a landscape of agricultural canals and conservation areas. The northern bank is densely settled with communities such as La Joya, Peñitas, Perezville, and Abram, supported by an extensive network of schools including Tabasco Elem Sch and Chavez Middle Sch. South of the river, the Mexican interior features smaller settlements like Reynosa Díaz, El Triunfo, and El Barranco among a grid of irrigation works like the Canal Principal.
