Mile 0 of the Western section of the Gulf Intracoastal Waterway begins at the Harvey Canal in New Orleans at about Mississippi River mile 98. It extends for 682 miles west, all the way to Port Brownsville, Texas. I do not own charts for the Gulf Intracoastal Waterway. This waterway viewer presently covers miles 0 to 682. Do not use for Navigation purposes. If you find errors, let me know, maybe I will break down and buy some charts to correct this with. If you have old charts, data donations are accepted.
