About this map

Laguna Madre dominates the eastern landscape of this coastal quadrangle, where the shallow waters of the gulf meet a network of islands and points. The terrain is defined by its transition from the tidal flats and marshes of the Laguna Atascosa and Laguna de los Patos to the managed ranchlands inland. Historic property lines and rural life are centered around established outposts like Buena Vista Ranch, Granjeno Ranch, and La Coma Ranch, which are served by a grid of coastal roads including Buena Vista Blvd and Bayside Dr.

Navigation and aviation infrastructure are critical components of this 2010 survey. The Port Isabel-Cameron County Airport is a prominent landmark in the southwestern quadrant, while a string of navigational aids, including Light Fiftynine and Light Sixtynine, mark the navigable channels within the lagoon. Water management for the local cattle and agricultural operations is evident through features like Cain Reservoir 1 and Cameron Company Fwsd Reservoir 1, illustrating the sophisticated irrigation and drainage systems of the Rio Grande Valley.
