The winding Arroyo Colorado carves through this Cameron County landscape, anchoring the community of Rio Hondo. The area’s reliance on water management is evident in the numerous impoundments, including the Abbott Reservoir, Montgomery Reservoir, and the distantly placed Reservoir Number Seven. These water bodies and the surrounding canal networks, such as the Lateral R Canal, define the agricultural productivity of the Rio Grande Valley.
