Get a map and go to east Galv bay / anahuac refuge area. Or see this link >>>
http://www.fws.gov/southwest/refuges/texas/anahuac/anahuac%20vicinity%202006.pdfDrive in the park and keep going down the gravel road a ways until you see the bay on your right. I have caught 'em wade fishing there. Very isolated, but you will see other wade fisherman and a few yaks too. Good area when wind is out of the north. If you decide on a guide try Dickie Colburn for Sabine Lake at sabineconnection.com
In any case try some soft plastics, top waters, 'suspending-type' baits like corkys, Mirrolure Catch V - all should produce.
Good luck.
