2019 Map of Hawk Island

About this map

The coastal wetlands and marshy expanses of the South Texas coast define this 2019 survey, where the Intracoastal Waterway cuts through the shallow waters of the Laguna Madre. The landscape is a complex network of low-lying terrain and island features, including Hawk Island, Chubby Island, and Mullet Island. This region, near the Willacy Co Cameron Co line, illustrates the environmental infrastructure of the Rio Grande Valley, specifically through the North Floodway designed for regional drainage. While much of the area is dominated by water and tidal flats, legacy infrastructure like Old Alice Rd hints at historic overland routes through these coastal reaches. These named rises, such as Green Hill and Goose Hill, provide sparse elevation within an otherwise saturated environment.
