Alot of the sight fishing I do is in dirty water. I catch ALOT of redfish rooting up shallow with their backs out of the water. We call it "backing" or "crawling" fish. They will work right along the shoreline up shallow like that. I like to look for them like that when the water level is low enough that it has dropped down out of the shoreline grass.
Sometimes we catch tailing fish in water that is too dirty to see them otherwise. This time of year crawlers are my mainstay and tailers are a bonus in alot of the areas I fish.
Get the heck out of that Galveston Bay toilet and fish from POC South. I was up on the sand between Mansfield and the Arroyo Colorado this last weekend and it literally looked prettier than the flats I was fishing in the Yucatan two weeks ago! There is just too much sediment from all the rivers dumping into SE Texas for the sight fishing to be what it otherwise could be. Sure, the can look for waking fish and "crawlers", but you need to head south for the sight casting experience you really want. I am originally from Houston and used to fish Christmas Bay. There is pretty good sight casting conditions from time to time, but the fish are spookier than hell and the fishing is incosistent at best.
The clearest water, in fresh- and saltwater, is near or over grass beds. There is definitely more grass as you move south on the Texas coast. I understand that Galveston Bay had a lot more grass in it until the 1950's when chemical dumping wiped out most of the grass beds.
if you have a boat or a kayak launch at pirates right at dana cove/ Go out the channel and take a left and all of the water there is as clear as Rockport, POC, or Indian river in Florida/decent sight casting/lots of grass, islands etc.../ If you don't care about being a purist then use a spoon fly and that is all you need. Thats "where to look" in the Galveston bay system. Post your email address and I would be happy to take you sight casting sometime. I have a Hells bay skiff and could show you some good water.
You are right CYO, I used to fish there a lot and complained that the water was too clear. Wait until winter and our bays will be clear as drinking water, well almost. Then you will be looking for mud streaks and mud boils because that is where you will find the fish.
