Fishing brackish river

I have been working in Dow, Plant B for the last 3 years and am right by an outfall into the Brazos. Most redfish I have ever seen in my life. I am not sure about fishing 18 miles upriver but you may have some success if you can fish as close to Dow as possible. I have see an unbelievably big school of reds hitting the surface by a log pile right where the outfall hits the river. There is a little cut that gets logjammed every so often each year and the reds just kill it. I have also seen some 4'+ tarpons rolling with the reds in the outfall. Inside the plant I have seen so many reds together stacked up in outfall you could walk across it.

Also, my buddy has Kayaked from our neighborhood(on the Brazos) to the gulf on the Brazos 4 times and said there isn't much on it besides some sandbars. I don't think you can do much if any fishing any farther north than where you are.

Just bring a big variety of bates for either trout/reds or bass. Maybe see about picking up some live bait also if you can. Good luck.
