The water, the locks and the wind — on one screen.

TowTide gives towboat crews on the Texas and Louisiana Gulf Intracoastal Waterway the current in MPH, the floodgates, lock status, and which side of the tow the wind is on. Plan a run and see your ETA at every lock, bridge and crossing.

Available in the United States on iPhone and Android.

Built for the wheelhouse

Current in MPH

Real water speed, not just tide height. Flood, ebb or slack at a glance, the next slack, and the next high or low, from NOAA predictions.

Floodgates & locks

Brazos and Colorado floodgates gate by gate, and the lock chambers from Texas into Louisiana, with closures reported by the Corps of Engineers.

Which side is the wind on?

Set your direction and loaded or light. TowTide tells you if the wind is on the bow, the beam or the stern, and warns on a beam wind in cuts and at bridges.

Run planner

Pick FROM and TO by mile or place, set your speed, and get an ETA at every lock, floodgate, bridge and crossing, with the forecast for when you get there.

Side channels

Houston and Texas City ship channels, the Mississippi and Port Allen route, the Colorado River up to Bay City, and Chocolate Bayou.

Your own spots

Save crew-change docks, fuel, moorings and wait spots on the chart, with a short note. Plan a run from or to any of them.

NOT FOR NAVIGATION. TowTide shows public NOAA, NWS, USGS and Army Corps data that can be late, wrong or missing. Predictions do not account for wind, river stage or pressure. It does not replace charts, Notices to Mariners or the lockmaster. Always confirm with the lockmaster on the VHF before committing to a passage.
