Captain Paul’s response to ~ Cajuncraw ~
You are not the only one that has a problem running a route from the Empire, LA launches to the Empire Jetties. Experienced boaters are stunned by the loss of land in that area, turning the various bayous, canals, lagoons and bays into an open water lake. Those who do not visit the area recently may not recognize the way that was once a boater’s highway. It no way is even similar to how the area looked twenty years ago.
I believe that your chart plotter is sometimes showing where the channels and canals were once located, but remember that the Louisiana marsh is a living estuary. It is an ever changing area consisting of water marsh and islands surrounded by tidal ocean waters. Because of this, many boaters and marine captains do not like to give specific points which would make up a route as the route may change because of the water movement and obstructions that are in the area. I have actually observed a strong tide destroy the bank of a bayou near that area and on a later trip observed parts of a large oil barrel that was now nearly blocking the waterway.
In addition, not knowing the draft, beam, range and fuel capacity can make it very hard for one boat to navigate the route but another vessel can easily get through it without any difficulties.
My point being that you should run any route that you did not mark yourself with extreme caution. Navigate the legs at a reduced speed and full attention to the topography of the area.
I believe that most of the canals and bayous there are marked with poles, but they do not even come close as how an officially recognized commercial waterway would be marked. Keep that in mind when you are running an unfamiliar route or one that you haven’t navigated for a while.
Some suggestions are that you should get some of the older maps of the area as they will show the area as canals and bayous as where they were. For instance NOAA Marine Chart 11358, Barataria Bay and Approaches shows the canal by the jetties as having a 9 foot depth, continuing with a 5-1/2 foot depth to the Empire gate, as of 1997.
This passage is via the Empire Flood Control canal to Bayou Long to Bayou Fontanelle to the Jetty canal to the Gulf of Mexico. This route is generally a north/south water but one cannot simply run a 180° course as that would put over many of the small reefs, shoals and islands that now
through out the area.
In addition to the Standard Map that are aerial photo maps, check into the USGS Topographical maps of the area. These will give you an idea of how or where these bayous were located. Of course, following a larger boat out to or in from the jetties, when using the tracking feature of the will allow you to convert it to a route.
I have put together a route that you may want to view. My plots on the map were made before Hurricane Katrina, so there may be some areas that are now shallow or have obstructions. If you use the route, do so at an idle speed for the first run and keep a sharp eye out for obstructions.
