TowTide

Tide, current and lock status for the Gulf Intracoastal Waterway — Texas into Louisiana. Built for towboat crews, not beachgoers. CURRENT TAB • Favorites showing what the water is doing right now, each opening to a forecast at 0600 / 1200 / 1800 / 2359 • A map of 58 stations drawn from lat/lon — no map tiles, so it works with no signal • A searchable station list covering the GIWW from Sabine to Port Isabel • The 350: GIWW mile 350 at Bolivar Roads, where the Intracoastal crosses the Houston Ship Channel — ten channels under one card, each with its own forecast LOCKS TAB • Every lock from the Brazos floodgates to the Industrial Lock in New Orleans, collapsed to one line each • Open one for river conditions, per-gate current and head in feet and inches, VHF channel and chamber size • USACE-reported closures and stoppages — the only source that says a lock is actually shut • Mississippi River stages from Red River Landing down to Head of Passes DATA THAT TELLS YOU THE TRUTH • Never presents a substitute gauge as the real one — if the nearest gauge is 5 miles away, the card says so • Never shows a dead gauge's number — older than 24 hours reads GAUGE DOWN • MPH is real water movement; FT/HR is how fast the tide is rising or falling. The app never confuses the two • Live data from NOAA CO-OPS, USGS Water Services and the U.S. Army Corps of Engineers — no account, no tracking, no ads TOWTIDE PRO The four-times-a-day forecast on every station, unlimited favorites, and full lock detail. Monthly (first month free), yearly, or a one-time lifetime purchase. Without Pro, TowTide stays usable with up to three favorites. NOT FOR NAVIGATION TowTide is an information tool. Predictions are astronomical and do not account for wind, river stage or barometric pressure. Always confirm with the lockmaster on VHF 13.
