Gulf Intracoastal Waterway Along Gulf of Mexico – July 30th, 200925.9N 97.4W
The Gulf Intracoastal Waterway is the portion of the Intracoastal Waterway located along the Gulf Coast of the United States. It is a navigable inland waterway running approximately 1700 kilometers (1050 mi) from Carrabelle, Florida, to Brownsville, Texas. The waterway provides a channel with a controlling depth of 3.7 meters (12 ft), designed primarily for barge transportation.
The lower section of this waterway, along the coast of Texas, visible here, includes the US portion of the Laguna Madre. The Laguna Madre comprises two long, shallow bays along the western coast of the Gulf of Mexico separated by the outlet of the Rio Grande; one bay is in the USA and the other in Mexico. Here, the upper bay appears white due to sun glint, while the lower bay is light green in color.
